The Asmari Formation (Oligocene-Miocene) is one of the most importance reservoir rocks in the Zagros Basin. This formation in the Mansouri Oilfield is composed of the mixture of silisiclastic - carbonate deposits which silisiclastic deposits are known as the Ahwaz Sandstone Member. Rock typing is a process in which geological facies determined with their dynamic behavior. Each flow unit is related to flow zone indicator, thus zoning of a reservoir using of flow zone indicators and identification of Flow units can be used to evaluate the reservoir quality based on relationship between porosity and permeability. To evaluate the reservoir quality and determining spatial distribution of petro-physical indexes in the Asmari Formation Sandstone, porosity-permeability relationship as well as their relationship with the rock types is used and finally Flow Units and Rock Types have been identified. In this study, the Asmari Formation Sandstone is divided into four flow units A, B, C and D. Within recognized flow units, flow unit C is the best one in the terms of reservoir quality and flow unit D also has a good reservoir quality. Comparison of determined flow units with porosity logs (neutron, density and sonic), it is observed that sandstone successions of Asmari reservoir affected by diagenetic processes like fracturing, dissolution, dolomitic cementation and hydrocarbon migration before cementation and flow units C and D are more extended, so porosity logs show good reservoir quality in this interval of Asmari succession. Thus it can be deduced that using hydraulic flow units, we can determine rock types groups in wells with core and then extrapolate the results into uncored wells. Manuscript profile

The best tools and methods in geochemical evaluation of source rocks are Rock-Eval Pyrolysis and Gas Chromatography. In this study, in order to evaluate geochemical characteristics of Ilam, Laffan and Sarvak formations in well NH01 in Nosrat Oil Field, geochemical data including preliminary and detailed Rock Eval Pyrolysis, bitumen extraction and Gas Chromatography on 15 cuttings samples (7 samples from Ilam, 6 samples from Laffan and 2 samples from Sarvak formations) were used. Results of pyrolysis indicated that most samples have a mixture of kerogen type II and III that often tend to be kerogen type II. In general, Ilam, Laffan and Sarvak formations are poor in organic matter and have lower hydrocarbon potential and maturities. Results of liquid chromatography for Ilam and Sarvak samples indicated that these samples are paraffinic in origin. Gas chromatography suggested that Ilam and Sarvak formations deposited in anoxic conditions containing organic matter mostly derived from marine environment with subordinate amounts of terrestrial input.

In this research, bioremediation potential of the aquifer located beneath Shazand Oil Refinery Company was evaluated according to the hydrochemical characteristics of groundwater samples. Groundwater quality determined by sampling from different locations and specifying some hydrochemical parameters such as EC, DO, T, pH as well as concentration of the major ions (Ca2+, Mg2+, (K++Na+), SO4-2, Cl-, (CO3-2+HCO3-)), some heavy metals (Fe+2, Mn+2) and nutrients (N-3, SO4-2). The results revealed that the amount of pH and EC provided a suitable condition for biodegradation of hydrocarbon contaminants. Dissolved oxygen concentration of the samples shows a suitable condition for aerobic biodegradation, however, there is not an optimum condition based on the average temperature and nutrient concentration. Carbon to nitrogen and to phosphorus ratios and also nitrogen to phosphorus ratio are not suitable in the optimum range. It means that in the case of site remediation the aquifer of the area has not adequate ability to conduct natural bioremediation and so an enhanced remediation operation will be inevitable.

Estimation of in-situ stress tensor in sedimentary basins using information obtained from exploration and development oil and gas wells during the drilling and logging process may be used for estimation of in-situ stress tensor in sedimentary basins. The in-situ stress magnitude and orientation and the resulting stress regime around the studied wells have been several application in secondary recovery programs from hydrocarbon reservoirs as well as wellbore stability analysis. In this paper, the magnitude of in-situ stress is estimated by using abovementioned data in some oil wells located in the south west of Iran. Increasing the oil production by hydraulic fracturing design and sand control in the multi-layer reservoirs such as the Marun giant oil field with loose sand horizons and also improving drilling performance in the Gachsaran formation¬ requires knowledge about the prevailing stress conditions. This research, tries to analyze the stress regime of the Asmari and Gachsaran Formations around the selected wells in the Marun and Lali fields using constructed Mechanical Earth Models (MEM) and their differences are discussed. The calculated stress magnitudes in studied wells indicate a significant drop in magnitude of horizontal stresses from the Gachsaran to Asmari reservoirs in the Marun oil field. The magnitudes of the three principal stresses resulted that SHmax is the maximum principal stress and the Shmin is the minimum principal stress, thus a strike-slip stress regime (SHmax>Sv>Shmin) dominates in the Gachsaran sequence and the Asmari formation of the Lali oil field. however, in the Gachsaran formation of Marun giant oil field, stress regime is reverse-strike slip but normal stress regime is dominated in it's Asmari reservoir. The In-situ stress condition indicates that the structural condition and the depth difference of these structures plays an important role in the tectonic stress regime changes. Manuscript profile

Wellbore instability is one of the main problems during drilling of oil and gas wells. Analyzing and wellbore instability prediction is important. In-situ stress measurement and stress regime are important for stability studies. This study was carried out in one of the oilfields in the south Caspian basin in Iran. The compressional stress regime in the studied field was determined based on regional stress indicators and larg scale tectonic observations. . This study presented the effect of borehole inclination and azimuth on borehole stability under reverse fault regimes. The magnitude of stresses was determined from measured sonic velocities, density log and predicted pore pressure utilizing the Eaton method. In this study, the modified Lade model have been utilized to perform stability calculation for different inclinations and azimuths. In this study, to perform stability calculation with the use of STABview software is presented. It is shown that drilling wells parallel to maximum in-situ horizontal stress (NE-SW) causes less stability problems. The results of this study could help in the mitigation and/ or prevention of wellbore stability issues in this oilfield. Manuscript profile

This paper aims to show that, during the past four decades, the literature on Rentier State, contrary to popular opinion, has not been consistent, whether in content or in methodology. Based on their methodological framework, the studies have been classified into two distinct types. The first generation of studies emerged in 1970s, but their failure at explaining the situation of oil-rich countries and clarifying the consequences of fall in oil incomes sever criticisms. The criticisms in connection with the first wave of the studies provided a ground to revise the methodology, and the way of conceptualizing foreign rents and their assessments. This resulted, particularly since 1990s, in the second wave of studies a wave that could be considered as revisionism. This approach brought new variables into the studies. It paid more attention to the historical background of oil-rich countries and the historical periods when oil incomes raised (with respect to the various stages of formation of the government and the regime in power). It focused on the interrelationship between oil rent and social and political condition of these countries, avoiding structural look to the oil rents. Some of the supporters of the new approach proposed new criteria for evaluation of oil incomes. This approach offered the possibility of more complex analyses, especially in the areas of political stability and democratic transition in the oil-rich countries, analyses that better explain different experiences of the oil-dependant states.

This article seeks to shed light on the question of what is moral politics and what is its place in the political and moral thought of our time? The article argues that the separation between the two realms of politics and ethics, which Machiavelli has largely proposed, may and should be considered a positive achievement for both, but the simple, classical, and absolute form of this separation isn’t defensible in our contemporary political and moral thought. For this reason, this article, based on the teachings of one of the most important philosophers of ethics, "Emmanuel Levinas", has tried to help strengthen the theory called "Ethical politics" and by defining ethics as the first philosophy and politics as an instrument to actualize the foundational ethical “Hospitality”, find a way to link ethics as teleology of peace and politics as its practical agent. The second part of the paper extracts and clarifies Mohammad Mossadegh’s notion of “the relationship between ethics and politics”—which serves as the foundation and source of his political activities—from his letters, memoirs, lectures and treatises. A presumption of this paper is that Mossadegh had developed a project within the political sphere which can be deemed as ethical in certain respects. I argue that this project can in turn be interpreted as an indication of the unity between the ethical and political spheres in Mossadegh’s thought. Manuscript profile

Because of the long-term nature of the upstream contracts of the oil industry, it is always possible for these contracts to be subject to fundamental changes in the situation. In such a way that economic, political, technical or economic, economic or economic changes will overcome, in such a way that it is difficult for one party to fulfill the obligation, while the other party may benefit from these conditions. In such a case, re-negotiation is one of the solutions that can help resolve this problem. What many of these contracts today are of interest to the parties. Using this method, the parties can review the contract and allow it to continue to be implemented, the parties are required to observe ethics and goodwill to pave the way for an agreement to resolve the problem and exit the stalemate. . Re-negotiation may be entered in the conditional condition at the time of the conclusion of the contract or after agreement of the terms of the parties. This condition will stabilize the contract, and this will encourage foreign companies to invest in oil projects, which will result in economic development of the host country. In fact, this is a condition of a dispute resolution mechanism that prevents the liquidation of the contract in the event of a change of circumstances. However, observance of ethics and good faith requires the contracting party to seriously negotiate and make rational and enforceable proposals. Manuscript profile

The deterioration and detrimental consequences of unnecessary exploitation of nature and the environment and the emergence of various pollutants, endanger human life and other creatures on Earth, and the development of comprehensive planning that damages and pollutes the environment Life has led environmentalists to the theoretical foundations of human interaction with nature, including ethics. The consideration and observance of the principles of environmental ethics that are in line with the ideals of divine ethics and at the same time include economic development and prosperity are more serious than ever in explaining the theory of appropriate environmental ethics, It is one of the necessities of protection and exploitation of the environment. The environment is anything around us that affects us and we can influence them. From Islam's point of view, the most important are: justice in the environment, environmental development, environmental protection and prevention of environmental degradation and pollution, destructive effects of development plans, optimal consumption , Environmental health, the creation of a recycling system, and so on. Given the status of the oil industry in today's world, it should not be left out of control and ignored by human and environmental damage, but should seek solutions. To reduce these damages. Today, refineries emit millions of pollutants into the air, posing a serious threat to human health and the environment. In this article, while considering the ethical and legal principles of the environment, the environmental considerations in oil contracts and the position of Iranian laws and regulations are examined.

Many large organizations today use entrepreneurship as a way to gain a long-term competitive advantage. The importance of entrepreneurship in different industries and areas is not the same for governments and some parent industries such as the oil industry have a special place, so the purpose of this study was to analyze the factors affecting the development of entrepreneurship in the oil industry. This research was applied in terms of purpose and descriptive-survey in terms of implementation method, which was performed by mixed exploratory method. In the qualitative stage, the research team consisted of 28 university experts who were selected by judgment and snowball method. In the quantitative stage of the statistical population, all oil industry experts were 3710 people. The sample size according to Krejcie and Morgan table was 348 people and simple random sampling method was used. The Delphi method has been used to identify the factors and the structural equations method with the Smart Payals software has been used to analyze the relationships of the variables. The results showed that the effective factors on entrepreneurship development include 27 components in the form of six dimensions (environmental-institutional, blue ocean strategy, opportunity, human factors, organizational factors, managerial factors). Also, the analysis of structural equations showed that environmental-institutional (0.386), blue ocean strategy (0.423), opportunity (0.342), human factors (0.318), organizational factors (0.370), managerial factors ( 0.455) have a positive and significant effect on the development of entrepreneurship in the oil industry. Finally, it can be said that the entry of entrepreneurship into this industry can save the oil industry from the current inefficiency and lead to solving problems such as oil equipment and oil sales.

Aiming to survey how the increase in oil revenue influenced on the collapse of the second Pahlavi regime, the present article is formed based on the theory of “rentier state”. In this regard, the paper maintains that considering Mohammad-Reza`s government as a rentier state would allow to conceive its structure and the ultimate decay. According to the theory, such description might be applicable to those states which a large majority of their overall revenue comes from regular foreign revenue rather than national production cycle. Such performance, negatively affecting the economic, social and political realm of the society, is much likely to end up in the legitimacy crisis and the collapse of the state itself. Accordingly, having become a rentier state from late1950s on, due to the rise in oil revenue, the second Pahlavi reign encountered some negative impact of such situation on its economy, politics, and society, which, all in all, had de-stabilizing effects on regime. Ever-increasing governmental domination over the economy, rise in the proportion of oil-driven revenues in governmental budget and development policies, a more autocrat king, extension of security/ intelligence services and, consequently, a more political oppression, taking control the society by bureaucracy, prevalence of financial corruption and promotion of rent-seeking ethos, and propagating the formal/ government-run culture by the regime are some of the most significant such effects. Hence, this situation caused to a gap between government and the people, their distrust in regime as an illegitimate one, and, consequently, contributed to its collapse in 1979. To explain the data, the present paper takes advantage of a descriptive-analytic method Manuscript profile

The subject of pricing in the oil market has undergone changes as the market evolves over time. Today, PRA reporting to private institutions that disseminate information, and especially prices in the world oil market, play an important role in determining the price of oil in the physical and paper markets. Concerns over the activities of these institutions have led to the formation of oversight bodies. However, the question remains as to what is the appropriate model for the interaction of price reporting institutions and supervisory bodies in a way that results in a more efficient oil pricing mechanism. The purpose of the present study is to review the theoretical foundations of the activities of price reporting institutions and supervisory institutions, using a data-base theory and using the opinions of experts in global oil markets, to provide a model for the relationship of these actors. Following the implementation of the foundation's data strategy, 60 concepts were constructed, categorized into 7 sub-categories and 4 main ones. At the theoretical coding stage, a conceptual model was developed for the relationship between supervisory bodies and price reporting institutions. Manuscript profile

Mineral oil in transformer is used for its insulation property and thermal transfer to external environment. Transformer oil is always under air pressure variation effects due to contact to external by silica gel chamber and the pressure which depends on the height of sea level. Therefore air pressure can affect on insulation parameters and its age. Air pressure changing can cause oil viscosity variation. In this paper, the air pressure effects on oil properties are studied by the use of tests carried out and measuring of the insulation characteristics. In a laboratory environment, air pressure was changed from 40 to 1250 mmHg using a pump. Then conductivity/leakage current and breakdown voltage are measured and analyzed. These results are used to presenting estimation models and also for suggestion of a new simple model by mathematical methods and then the models were compared to each other. Manuscript profile

This research aims to evaluate the effectiveness of MBA programs that were held in National Iranian Oil Company from 1392 to 1393. In order to achieve the aim, first three levels of the Kirk Patrick’s Model (Reaction, Learning, and Behavior) have been selected as the evaluation basis of this study. The mixed method approach with triangulation research design has been used; this design consisted of two simultaneous processes, described here as collecting qualitative and quantitative data at the same time by use of different research tools. Research Participants were 30 high-ranked managers of NIOC who attended in oil mini MBA Programs. Research data gathered by different tools: quantitative data was derived from three questionnaires of Attitude Scale, Learning Self-evaluation, and Behavior Rating Scale; qualitative data was gained through a protocol which designed for doing semi-structured interviews. The collected data have been analyzed through quantitative/qualitative methods: Quantitative data has been examined by Effectiveness Rate and Pearson’s Correlation Coefficient; and qualitative information has been explored and interpreted through the procedure of Thematic Analysis. It is worth noting that the results validation has been done by Peer Review Audit (member checking). The overall findings show that the MBA programs of NIOC were not been effective and successful: effectiveness rate of level 1 (Reaction) is below desired point; for level 2 (Learning) it is a little above the desired point; and in level 3 (Behavior), like level 2, is below desired point. We definitely conclude that the MBA programs have not been successfully adapted to company context and needs, so not been accepted among top-level managers for whom the courses been developed. Therefore, transformation of learning (level 2) to behavior (level 3) was not occurred. It is also true that the participants’ dissatisfaction (level 1) with curricular aspects of programs led to insignificant learning. Manuscript profile

Current need for oil products and their applications in various fields, plus Iran’s potential has attracted significant investment in this field as the strategy of the Islamic Republic of Iran is to become self-sufficient and localize oil and gas industry.This study aimed to investigate the role of knowledge management in technological learning through the mediating variable of research and development activities in an oil and gas organization.To this end, a research model was presented based on theoretical studies, which yielded three hypotheses. A valid and reliable questionnaire was used to collect data to test the research hypotheses. The statistical population of the study included managers and experts of the company under study (n > 100). Due to the abnormality of data distribution, Smart PLS software was used to test the hypotheses. According to the software outputs, knowledge management affects research and development activities, research and development activities affect technological learning, and knowledge management affects technological learning. Therefore, better implementation of technological learning requires special attention to the creation, sharing and application of knowledge and experience that exists in the organization.

Process management in the organization requires the creation of process insights throughout the organization. In this regard, organizations need a comprehensive method to evaluate the implementation of organizational processes that determine the factors affecting the implementation of organizational programs. For this purpose, it is a responsive way for organizations that, in addition to creating awareness of the effective factors, provide a roadmap to improve the realization of the organization's plans and visions. In the present article, to facilitate the management of processes in the East Azerbaijan Province Gas Co., a Hybrid Process Maturity Model has been developed. This model has been presented and implemented with a combined approach of selected maturity models, considering the limitations of maturity models, which makes the models not comprehensive enough. The capability of the proposed model framework, unlike other models, is that the above model can be evaluated in detail. In this regard, first, the key processes of the company have been identified. Then by collecting the required information on how to implement the processes, the maturity levels of the key processes of the organization have been evaluated according to the proposed model and current level, the desired level of maturity is set. Implementing solutions also have been proposed to improve the processes. According to the collected information, 16 of the 26 Key Processes of the East Azerbaijan Gas Co. are at level zero or incomplete process implementation, eight processes are at level one or planned and two processes are at level two or controlled.

Abstract Determination of In-situ stress domain in oilfields is so important for drilling, well completion and petroleum geomechanics. Simply, determination of magnitude and direction of In-situ stress around wellbore is the first step of geomechanical studies and wellbore stability particularly. Preliminarily, because of importance of casing collapse problem in the Marun oilfield, the magnitude of in-situ stress is determined. The magnitude of vertical stress (Sv) was in range of 85 to 90 MPa. The minimum horizontal stress (Shmin) determined by some analytical methods. For estimating of maximum horizontal stress (SHmax) domain we used Anderson’s faulting theory and stress polygon. So the magnitude of SHmax was so close to Sv and the faulting regime shows normal/strike slip. Within Gachsaran Formation in depth of collapses because of salty lithology and high pore pressure, magnitude of In-situ stress is so close and it can be assume hydrostatic stress state.

Abstract This study aims at geochemical investigation of the hydrocarbons contained within the Azadegan sandstone reservoir by using the GC and GC-MS techniques. The Azadegan reservoir contains paraffinic and paraffinic – naphthenic oils with an API of 30. The gas chromatograms reveal that the source rocks responsible for these oils contains mainly type II kerogen deposited in a reducing environment. According to these data the studied oils have a relatively high level of thermal maturity. Ratios of C35S/C34S, C29/C30, C31R/C30 Hopane and Pr/Ph, Ph/nC18 show that the studied oil derived from carbonate source rock; which is also evident form Pr/Ph Vs. DBT/Phen diagrams. Diagrams of (20R) C29/C27 vs. Pr/Ph as well as the ratios of C21+/C21-, Pr/P, TAR are consistent with abundance of algal organic matter. Presence of Tricyclic terpanes, higher ETR ratios and diagrams of δ13C vs. Pr/P introduce a Jurassic aged source rock for the studied oils. Based on biomarker and isotopic data it could be concluded that oils within the Azadegan reservoir are mainly derived from carbonate source rocks of Mid-Upper Jurassic which are deposited in paralic/open marine environment with a predominance of algal organic matter.

The Oligo-miocence Asmari Formation in the Cheshmeh Kush Oil Field consists of a mixed carbonate-siliciclastic succession. The carbonate intervals of the Formation display a high degree of vertical heterogeneity created by a complex diagenetic history. This study is aimed to investigate the effect of diagenetic events on reservoir quality of carbonate intervals of the Asmari Formation. Core samples and thin sections were studied from sedimentological and diagenetic point of view. Results from cathodoluminesence and scanning electron microscopy were used to investigate diagenetic features in details. Core analysis data (porosity and permeability) and wire-line logs (porosity and oil saturation values) from studied interval were used in order to examine reservoir properties. Diagenetic studies and their comparison with petrophysical data demonstrated that dolomitization, cementation (calcite, anhydrite and celestite cements), compaction and dissolution are the most important diagenetic events affecting porosity and permeability of the reservoir. Based on vertical distribution of diagenetic features and reservoir characteristics, diagenetic zones (DZ) of the carbonate succession were introduced. Medium crystalline dolostones with sparse compaction features and limited anhydrite cement (DZ-23, 27 and 30) comprise the highest value of porosity and permeability. Whereas intense mechanical and chemical compaction and evaporate (anhydrite and celestite) cementation in some dolomitic intervals have thoroughly reduced reservoir quality (DZ-12, 11 and 24). Compaction and calcite cementation (coarse spary, equant and poikilotopic types) in some limestone intervals damaged reservoir properties and created non-reservoir intervals (DZ-3, 20 and 17). In contrast, high value of interparticle and dissolution porosities along with minor compaction and cementation effects has improved reservoir properties of the Asmari limestones (DZ-31 and 32). This study shows that the reservoir characteristics of the Asmari Formation in the studied field are dominantly affected by diagenetic events and therefore diagenetic studies and determination of diagenetic zones in field-scale are the most important part in static reservoir modeling and Manuscript profile

This study is aimed at petrophysical evaluation of the Ghar reservoir using Multimin method by Geolog software in five wells from the Abouzar oilfield. For this purpose, well log data comprising of neutron, density, sonic, gamma, resistivity and photoelectric absorption were utilized and their analysis lead to determination of quantitative petrophysical properties such as porosity, volume of shale, water, oil saturation and qualitative parameters including lithology and clay mineral types. The analyses revealed that three zones could be identified in the Ghar reservoir. Meanwhile, there are three shaly interlayers within the Ghar foemation. By application of the cutoff values on oil in place (OIP), petrophysical properties were determined zone by zone and based on Net to Gross ratio (N/G) high reservoir quality zone was identified. Finally by using clustering algorithm, reservoir rock types were identified based upon six properties including density, neutron, gamma ray, volume of shale, water saturation and effective porosity. The facies were introduced on the basis of their priority in reservoir quality so that there is an agreement between petrophysical evaluation results and electrofacies. General lithology of the reservoir in composed of upper loose sands and consolidated sand in the lower part. The lower sands are consolidated by the calcite cement. Overall, the volume of clay minerals in the lower part is less than that of upper part. However, productive zones were separated by a thin shaly layer. The clay minerals type in the shaly layer differs from those present in the reservoir rocks. Total and effective porosity are almost identical which is due to low volume of shale. Manuscript profile

Porosity parameter is an important reservoir property that can be obtained by studying the well core. However, all wells in a field do not have a core. Additionally, in some wells such as horizontal wells, measuring the well core is practically impossible. However, for almost all wells, log data is available. Usually these logs are used to estimate porosity. The porosity value obtained from this method is influenced by factors such as temperature, pressure, fluid type, and amount of hydrocarbons in shale formations. Thus it is slightly different from the exact value of porosity. Thus, estimates are prone to error and uncertainty. One of the best and yet most practical ways to reduce the amount of uncertainty in measurement is using various sources and data fusion techniques. The main benefit of these techniques is that they increase confidence and reduce risk and error in decision making. In this paper, in order to determine porosity values, data from four wells located in Azadegan oil field are used. First, multilayer neural network and multiple linear regressions are used to estimate the values and then the results of these techniques are compared with a data fusion method (Bayesian theory). To check if it would be possible to generalize these three methods on other data, the porosity parameter of another independent well in this field is also estimated by using these techniques. Number of input variables to estimate porosity in both the neural network and the multiple linear regressions methods is 7, and in the data fusion technique, a maximum of 7 input variables is used. Finally, by comparing the results of the three methods, it is concluded that the data fusion technique (Bayesian theory) is a considerably more accurate technique than multilayer neural network, and multiple linear regression, when it comes to porosity value estimation; Such that the results are correlated with the ground truth greater than 90%.

Darquain anticline is located at 5 km northeast of city of Abadan. The axis trend of this oilfield is north through south. In this study, Kazhdumi, Gadvan, Garu and Sargelu Formations in Darquain Oilfield, in Abadan Plain, were analyzed by Rock-Eval 6 instrument. S2 vs. TOC plot revealed that kerogen type in this oilfield predominantly is of mixed of types II & III. Significant S2 Adsorption by matrix of Kazhdumi Formation in well numbers 1 and 2 (5.33-14.06 mg HC/gr rock) and Gadvan Formation in well numbers 2 and 3 (3.1-3.2 mg HC/gr rock) is due to low thermal maturity as well as low Gas-Oil Ratio factor. In Garu and Sargelu Formations amounts of adsorbed S2 by matrix are respectedly 0.82 and 0.84 mg HC/gr rock, that represent a medium thermal maturation and medium to high Gas-Oil Ratio factor. Quantity of TOClive in the Kazhdumi, Gadvan, Garu and Sargelu formations estimated to be in the range of 0.6-1.6, 0.2-1.9, 1.53 and 8.38 by weight percent respectively. This represents potential for the studied formations fair to excellent petroleum generation. Also the studied wells were modeled, by which the Ro of the source rocks were calculated according to their depth. Also transformation ratio of organic matter and the initial TOC is estimated. Transformation Ratio of Kerogen in studied formations ranges from 0.12 to 0.66. This is in accordance with estimated Easy Ro by PBM software (0.5-0.8). It can then be concluded that Kazhdumi Formation is in early oil window and already started to generate hydrocarbon. This is also verified by Tmax data. The Gas-Oil Ratio of Kazhdumi and Gadvan Formations is 0-1 indicating variable hydrocarbon generation. Also this factor for Garu and Sargelu is 0.58-1 indicates that they have more gas generation potential rather than oil generation potential. The inferences drawn from It can be inferenced from iso TOCoil and TOCgas maps led to the conclution that, in west and southwestern parts of the basin, the depth during deposition of mentioned formations was more in compare to other parts of Darquain.

Due to subsurface heterogeneity and existing vagueness in geophysical interpretation, identifying and interpretation of facies in wellbores is always prone to uncertainty and risk. Nowadays several methods have developed for quantitative facies interpretation. These methods are generally divided into deterministic and stochastic categories. Deterministic methods, in spite of their simple modeling procedure, cannot expose the amount of error or accuracy of the model. On the other hand, stochastic methods, in addition to quantifying the error of the model, can provide the probability of the model’s accuracy in each point of the reservoir. The Bayesian approach is one of the stochastic methods that use conditional probabilities for modeling. This approach, as well as probabilistic modeling of hydrocarbon facies, quantitatively computes the effect of additional data in decreasing the error of the classification. Information entropy theory, by quantifying the intrinsic uncertainty in each model input parameter, can easily provide the selection of valuable parameters. The present study was carried out on one of the wells of Mansuri oil field, south of Iran. After generation of training data by using rock physics techniques and Gassmann’s relation, the value of each input parameter was identified by entropy analysis. Then, by use of Bayesian analysis and valuable parameters, oil facies classification and discrimination was implemented. The five optimum parameters were elastic impedance, compressional wave velocity, shear wave velocity, density and porosity .The amount of error in this method is approximated to be 11 percent. This investigation also showed that gamma ray parameter does not have a drastic positive effect on identification and discrimination procedure of oil facies, which has a good agreement with the results of entropy analysis .

Kilorkarim oilfield is located in 40 Km North of the Persian Gulf and in the vicinity of Siah Makan, Golkhari, Bibi Hakeemeh oilfields. The present study focuses on geochemical evaluation of probable source rocks in this oilfield. For this purpose, source rock samples that selected from three wells were evaluated using Rock-Eval pyrolysis and reconstruction of burial history modeling. The results show that organic matter of these source rocks are mostly a mixture of Kerogen types II and III. Also organic petrography study showed that Vitrinite, Detrovitrinite, Hominite and Fuzinite macerals in Pabdeh, Gurpi and Kazhdomi Formations, and reworked Bitumen in some sections of the Pabdeh Formation. Based on Vitrinite Reflectance measurments in well#1, Pabdeh and Gurpi Formations aren’t interred in oil window and Kazhdumi Formation interred in oil window. In well#2 Pabdeh and Gurpi Formations are in the beginning and in oil window, respectively. In well#4 Vitrinite Reflectance is emphasized the entrance of Kazhdumi Formation into oil window. Reconstruction of Burial history and thermal modeling was performed by PBM 1D software. Modeling showed that Pabdeh Formation in well #1 and 4a interred in oil window but the opposite is true for middle section of well #2. Because of more deposition of Aghajari Formation in the south part, oil window occurs in shallower depth and therefore the maturity is higher in the south toward north of the oilfield.

Porosity is one of the main variables in evaluating the characteristics of an oil field. Petrophysical data are normally used to determine these variables. Measurements obtained from well logs, containes some errors and uncertainty. This porosity is influenced by different factors, such as temperature, pressure, fluid type, clay content and the and amount of hydrocarbons. One of the best, and yet most practical ways to reduce the amount of uncertainty in porosity measurement is using various sources of data and data fusion techniques. Data fusion increase certainty and confidence and reduce risk and error in decision making. In this research, the porosity is estimated in 4 wells of Azadegan oil field, with data fusion method (Bayesian theory). To check the ability of generalization of the method, the porosity was also estimated in one other well of this field. A maximum of 7 input variables were used to estimate porosity in this new approach. The results showed that data fusion technique is more powerfull than traditional tecniques for porosity estimation. According to the results, this method has higher credibility than traditional techniques that show 0.7 to 0.8 regressions with log data but data fusion technique showed solidarity over 0.9 with log data.

The Oligo-Miocene Asmari Formation is one of the main reservoir rocks of SW Iran with several decades of production history from different oil fields in the Zagros fold- thrust belt. One of the main reasons for the high quality of the Asmari reservoir is well developed fracture system in this formation. Characteristics of fractures such as type, opening and orientation can be determined by the core analysis and also interpreting the image logs. This paper attempts to compare the advantages of the image log and core analysis in detecting fractures and other geological feathers in different zones of the Asmari Formation. To achieve this goal, we have compared the image log and core of well no. 89 of the Aghajari oil field. Comparison of the core well no. 89 of the Aghajari oil field with its image log revealed distinguish of the bedding planes in the core easier and more reliable than the image log. This study demonstrates the image log is more capable than core to detect the open fractures, while it is not suitable for detecting filled fractures. Indeed, image log rarely can detect shear fractures, but if it is calibrated with core, it can detect shear fractures with reasonable accuracy. Manuscript profile

Kupal anticline is elongated and almost symmetric. This structure is located in Northwest of Ahwaz city and consists of two reservoir including Bangestan and Asmari. Kazhdumi, Pabdeh and Gurpi formations are probable source rocks and Gachsaran Formation constitutes the cap rock. Because project topic is defined on Bangestan Group, so reservoir studies of Bangestan is focused on Sarvak Formation. Rock-Eval and geochemical analyses conducted on source rocks indicated that Pabdeh Formation is at early stage of oil generation window in the Kupal oil field. Kazhdumi Formation has not been drilled at this field, so geochemical and maturity assessment of this formation has been evaluated using samples from adjacent oil fields including Marun and Haftgel. Geochemical analyses indicated that Kazhdumi Formation is mature enough and is considered to be the main source rock. The aim of this project is investigating Tar-mat in Bangestan reservoir in Kupal field. It is thought that Tar-mat layer was formed in vicinity of oil-water contact and can be related to processes including natural deasphaltening, gravity segregation and oil-mixing. Based on Rock-Eval pyrolysis, pyrolysis-GC performed on Sarvak oil, it is suggested primary asphaltene formed from source rock does not exist in the studied oil but it is derived from secondary asphaltene by chemical reactions occurring due to oil-mixing in production well. In addition, analysis performed on asphaltene in oil zone, oil-water contact and water zone suggest that Tar-mat was formed in oil water contact region due to oxidation process. This layer acts as impermeable seal and prevents water flow to oil Manuscript profile

Alkhalij field located offshore Qatar , was discovered in 1991 and put into production in 1997. The field is original in many aspects. it is one of the few carbonate reservoir with stratigraphic closure, the oil is being trapped in upper part of a monocline due to a lateral variation in reservoir facies. In addition, the reservoir lies within the capillary transition zone and consists of a succession of highly conductive oil bearing layers ( drains) in between matrix layers of poor permeability. High- resolution 3D seismic has revealed additional area developed, which were previously considered to be uneconomic. Resent 4D seimic pilot has given encouraging result to utilize Seismic Technologies to analyse the evolution of the Al Khalij oilfield over time.

Structural geological study is one of the most important stages of an oilfield exploration and production (E&P) program, since a knowledge of existing structures can play a fundamental role in the oilfield development plan. The main purpose of this study is to create three-dimensional (3D) structural models to determine direction of tectonic stresses at Lali oilfield using subsurface geophysical data. The study area is located within the so-called Dezful Embayment (northern Khuzestan Province, Iran). Accordingly, in order to provide a 3D model of the reservoir, geostatistical tools in Petrel Software were utilized. Incorporating density log data into several coded formulations in MS Excel Software, the reservoir had its modulus of elasticity calculated. Subsequently, maximum and minimum horizontal stresses were calculated using poroelastic equations. Fault modeling results showed that, fault dip increases with increasing the depth towards the center of the field. Obtained values of stress using the poroelastic equations show that σ_H>σ_h>σ_v, confirming a regional reverse stress regime, which is consistent with previous studies in this area. Also, the formal stress ratios (Φ = (σ2-σ3) / (σ1-σ3)) obtained from poroelastic equations and inverse analysis method were found to be well-correlated across the area. Finally, average azimuth of the reverse faults on the southern limb (as calculated by Petrel) and the fractures on the limb (as obtained from FMI images and core samples) were found to be N305 and N315, respectively (average = N310). Thus, N040E was inferred to be the average direction of principal stress, i.e. principal stress is mostly directed along a NE-SW axis (perpendicular to the general trend of Zagros Orogeny); this is probably a result of the activities of youngest Zagros orogeny phase. The agreement between the obtained principal stress directions by fractures, faults, and focal mechanism of earthquakes across the World Stress Map (WSM) confirms the validity of this study.

The rapid development of shale gas resources in the US has transformed the world gas-market outlook. Despite this, the consensus was for a long time that shale gas would not be a ‘game changer’ in the world as it has been in the US. Shale gas is extracted from solid rock using a process called hydraulic fracturing, or ‘fracking’. Static shows, in USA, production rates decline, for the most of well on average, 80 0r 85 percent over the three years. In order to maintain current level of shale gas production, Hughes estimates that the high rates of deterioration of such wells across the US will require the drilling of 7,000 new wells a year at cost of $42 billion annually. For the maintenance of overall production of shale oil, some 6,000 new wells would need to be drilled every year, an endeavor that would cost $ 35 billion. A number of environmental concerns have been raised about fracking, including the potential for seismic events, air pollution, surface and groundwater contamination, and greenhouse gas emissions. There is no doubt that shale revolution has been a game-changer in short term, but the implication shows that it is not sustainable in long-term. Manuscript profile

Investigating potential source rocks in oilfields is important. In this study, in addition to evaluating the hydrocarbon potential, the Arrhenius kinetic model was used to more accurately assess the source rock maturity status as well as the percentage of oil generation in the Parsi oilfield. In the Arrhenius model, the rate of kerogen decomposition is very important. In this research, some source rocks that have been tested by thermal pyrolysis were kinetically analyzed and the source rock conversion ratio (TR) was determined. Based on the results of burial history and thermal modeling, it was found that Kazhdumi and Pabdeh formations were in the oil window well while Gurpi formation did not enter the oil window due to poor organic matter content (TR = 0). Therefore, among the Kazhdomi, Gurpi and Pabdeh formations in the Parsi oilfield, Kazhdumi formation is considered as the main and most effective source rock of this oilfield with high TTI and TR = 100.

Determining the position of the production zone is one of the best ways to reduce drilling costs as well as quick access to the reservoir and optimal production of hydrocarbon resources. The purpose of this study, is to estimate the porosity, water saturation and thickness of an oil field in Iran’s southwestern Basin , and ultimately to reach the production zone. Therefore, according to the data obtained from 76 wells of this field, variation of reservoir petrophysical parameters were modeled with variogram operation and using Geostatistical methods. By using ordinary Kriging method, the values of the parameters were estimated in the whole field. Subsequently, by using the indicator kriging method, the field boundaries were separated in order to obtain the exact area of the oil zone and the volume of oil in place and finally by considering the 80% probability level, The definite boundary of the presence of the production zone was determined in the block model and In this zone the volume of reservoir’s hydrocarbon was estimated about 147/5 million cubic foot.

Some of the most prolific petroleum reservoirs with high gravities of oil in the world occured in the Upper Jurassic and Cretaceous carbonate formations in the Persian Gulf area .Most of the reservoirs are composed of pelletal,oolitic ,or bioclastic grainstones and reefal limestone that have high primary porosity and permeability .These reservoirs are sealed either by tight limestone ,massive anhydrite, or by impermeable rocks. The seals are effective throughout most of the Persian Gulf and surrounding areas, Accumulations of heavy oil and natural asphalts on the Iranian side of the Persian Gulf extend NE to SW along the Qatar arch. some of the geological structures which are located along this trend contain heavy oil and natural asphalts within post- Jurassic formations. The major geologic factor which caused accumulations of heavy oil within some geological structures is the Qatar arch. As a result ,some differences appear in lithologic units in two sub-basins northwest and southeast of the Qatar Arch. In general , the occurrence of heavy oil in this trend can be explained as follows; • Fracturing and joints within formation ; • Reduction of thickness of post- Jurassic sediments; • Facies change of Arab reservoirs, cap rock (Hith anhydrite), in some structures from anhydrite to dolomite and also pinchout; The absence of proper environment for the generation of high gravity oil may also be of importance .It should be mentioned that "F" structure (Ferdows), with huge amount of oil in Ratawi and Sulaiy carbonate reservoirs(Lower Cretaceous), is one of the largest heavy oil fields along this trend .The Farsi "B" structure, ( Farzad), with a thick Jahrum formation (Eocene) which has excellent reservoir properties, is filled with natural asphalts.

Drilling mud loss is considered as one of common problems encountered during excavation. The aim of this study is to evaluate of mud loss of the Sarvak Formation (Cenomanian age) in Azadegan oil field which is known as the most important rich hydrocarbon reservoir in the Zagros region by providing the model in the environment of GS+ software. This formation consists of a thick sequence of limestone and clay limestone layers, which is divided into 7 zones based on petrophysical characteristics. For this purpose, available data such as drilling mud weight, pump pressure, mud loss, and related depths of 9 drilled wells were investigated. The results showed that despite of the operating factors including the weight of drilling mud and the pressure of the pumps were kept constant, the presence of fractures in the reservoir rocks causes to occur mud loss significantly in zone 3 while it is observed the lowest level of mud loss in zone7. Based on the results of mud lost data patterns, faults, sedimentary environments morphology (such as sedimentary channels) seem to play major roles in creating fractures or areas susceptible to mud loss. The difference in observed patterns of mud loss is more likely to confirm the relocation of channel status over the time in different parts of the reservoir. In general, the highest rate of mud loss was detected in the northern and southern edges while the lowest rate was happened in the middle part of the field. It is suggested to prevent mud loss hazards in this field, underbalanced drilling method should be used. Manuscript profile

The first step in performing geochemical adaptations is to identify the molecular and hybrid structure of the oil. One way to match the use of infrared spectroscopy is to identify and compare the structure of oil samples. Infrared spectroscopy is a practical method with easy, low-cost interpretation and reliable results for determining the structure of organic compounds. Also, considering the significant growth of the tendency to develop fast, accurate and reliable analytical methods for industrial applications and also the discovery of new hydrocarbon resources in the sedimentary basin of Abadan plain such as Darkhoein and Yadavaran oil fields in recent years, indicates the need for more comprehensive studies. There is a sedimentary basin in this basin. Based on this, 15 samples of crude oil from Fahlian reservoir were selected and examined in the most important oil fields of this basin, namely Darkhoein (9 samples) and Yadavaran (6 samples) located in southwestern Iran. By dividing the samples by evaluating the crude oil, different analytical goals were achieved. Using infrared spectroscopy, the functional groups in the samples were determined and then the amount of these compounds in different samples was compared with each other. Based on the results of the mass spectrometer, the oils studied in this basin are divided into three families with different genetic characteristics. In this study, it was shown that infrared spectrometer is a fast, reliable and non-destructive analytical option and a complementary or even alternative method of chromatography and biomarkers analysis to perform various scientific and industrial purposes in the oil industry, including quality measurement, Quantity and geochemical evaluation of oil.

Analysis of a dynamic light scattering instrument "Wyatt DynoproNanoStar" was used to detect the accumulation of surfactant in the oil phase. Triple measurements were performed for each sample and at least two samples were tested for each level of surfactant concentration to ensure reproducibility. The detection temperature was controlled at the same temperature by segmentation experiments. The accumulation properties of BAC surfactant in toluene were investigated using DLS and samples were presented in Figure 3, including the total radius and intensity of the collected light signal, C12, C14, and toluene C16, from the oil phase in the water-oil partitioning equilibrium from the surface. Net BAC was sampled. As can be seen, both the particle radius and the intensity of the C12 and C14 signals varied sharply within the evaluated concentration range, indicating that C12 and C14 do not form micelles in toluene. In this research, a multi-physical model, integrated corrosion inhibition model (ICI), is presented theoretically and empirically to evaluate integrated water-oil separation, aggregation, adsorption / desorption, and corrosion inhibition of mixed surfactant inhibitors in water-containing oils.

Background: Deep-fried oils (DFO) produce toxins that endanger people's health. Using herbal supplements along with exercise training can help improve health. The purpose of this study was to investigate the effect of aerobic training (T) and octopamine (O) supplementation on VEGF and PDGFR gene expression levels in the heart tissue of rats poisoned with DFO. Materials and Methods: In this experimental study, 25 male Wistar rats were purchased and placed in 5 groups of 5 animals, including: 1) control, 2) DFO, 3) DFO+T, 4) DFO+O and 5) DFO+T+O. Over a course of 4 weeks, rats in groups 2 to 5 received DFO by gavage, and rats in groups 3 and 5 ran on the treadmill 5 times a week with moderate intensity; also, rats in groups 4 and 5 received 81 μmol/kg octopamine supplement intraperitoneally 5 days a week. The Kolmogorov-Smirnov statistical test, independent samples t-test and two-way analysis of variance were used to analyze the research findings (p<0.05). Results: DFO had a significant effect on increasing the gene expression levels of VEGF (p=0.001) and PDGFR (p=0.002); training had a significant effect on the reduction of VEGF (p=0.001) and PDGFR (p=0.012); also, octopamine consumption had a significant effect on the reduction of VEGF (p=0.001) and PDGFR (p=0.045). Conclusion: It seems that aerobic training and octopamine consumption alone have anti-inflammatory effects in the heart tissue of DFO-poisoned rats, however they do not have significant anti-inflammatory interactive effects.

Background and purpose: the use of heated oils has become an integral part of today's nutrition. Studies show that with the development of obesity, capillarization in adipose tissue does not occur in line with changes in cell size. Therefore, adipose tissue in obese people is always associated with lack of oxygen and it causes systemic inflammation by releasing inflammatory mediators. The purpose of this study is to investigate the effect of aerobic exercise and octopamine on HIF-1 protein concentration in visceral fat and white cells in rats fed with deeply-heated oil. Methodology: In an experimental trial, 30 male Wistar rats were divided into five groups: healthy control, control-heated oil, aerobic exercise-heated oil, octopamine-heated oil and exercise, and octopamine-heated oil. Octopamine was given to rats by IP intraperitoneal injection daily for four weeks and five days a week. Aerobic exercise was also performed for four weeks and five days a week with moderate intensity on the treadmill. Forty-eight hours after the last intervention, the rats were anesthetized and visceral adipose tissue was removed from the body to measure HIF-1a gene expression. As a result of receiving deeply-heated oil, the expression of HIF-1 gene and protein in visceral fat increased significantly (P=0.001), but the number of white cells in visceral adipose tissue increased significantly (P=0.001). Aerobic exercise significantly decreased HIF-1 gene and protein expression (P=0.01). In addition, octopamine supplementation had no significant effect on HIF-1 gene expression of visceral fat of white cells in rats poisoned with deeply-heated oil. Receiving octopamine also decreased HIF-1 gene and protein expression (P=0.002). In addition, exercise significantly reduced the number of white cells (P=0.001). Octopamine could significantly reduce the expression of HIF-1 protein and the number of white cells. The interaction of exercise and octopamine was significant for the expression of HIF-1 protein and the number of white cells. Findings: The results of this study showed that aerobic exercise and octopamine improve the angiogenesis process of the visceral adipose tissue that had been disrupted by heated oils, and reduce the damage caused by feeding with deeply-heated oils.

Background: Although the beneficial role of exercise and CBD oil in Myocardial infarction (MI) has been reported, the interactive effect of swimming training (ST) and CBD Oil (CO) consumption is still not well known. Therefore, the purpose of this study was to investigate the effect of eight weeks of CBD oil consumption on Ceramide gene expression in the heart tissue of rats suffering from heart infarction along with swimming exercise. Materials and Methods: In this experimental trial, 25 ovariectomized rats with myocardial infarction were divided into five groups, including (1) Healthy control (HC), (2) Myocardial infarction (MI) (3) Myocardial infarction+ Swimming training (MI+ST), (4) Myocardial infarction + 50 mg/kg of CBD oil consumption (MI+CO 50), and (5) Myocardial infarction + 50 mg/kg of CBD oil consumption+ Swimming training (MI+. +CO 50 + ST). Myocardial ischemia was induced by subcutaneous injection of isoproterenol (50 mg/kg intravenously) in myocardial infarction rats. Groups 3 and 4 received 50 mg/kg CBD as gavage on a daily basis for eight weeks, and groups 2 and 4 performed swimming training five days a week. One-way analysis of variance (ANOVA) with Tukey’s post hoc test was performed to analyze the findings (P < 0.05)).In this study, 25 rats were divided in 5 groups including: (1) healthy control, (2) patient control, (3) endurance training (3 days a week for one month), (4) recipients of mesenchymal stem cells (1 × 106 cells / Kg), and (5) simultaneous recipients of endurance training and mesenchymal stem cells. Alkaline phosphatase gene expression was assessed by RT PCR and the amount of osteopontin synthesis was measured by immunohistochemistry procedure. Results: Ceramide in the MI group had a significant decrease compared to the healthy control group (p=0.01). Compared to the MI group, only the MI group + swimming + CBD supplement showed a significant increase in Ceramide (p=0.01). Conclusion: Eight weeks of CBD oil consumption and swimming training can reduce heart tissue damage by increasing Ceramide expression. Manuscript profile

In this research, the process of lithological changes and diagenetic processes of Asmari formation with Oligo-Miocene age has been investigated. For this purpose, 400 samples were selected and collected from a section of the Masjid Suleiman oil field and the surface section of the Asmari anticline in the Dezful depression and the Gurpi anticline in the Izeh zone. Petrographic studies revealed 18 sedimentary microfacies that were deposited on a ramp-type carbonate platform. Among the significant diagenetic processes in the region are the process of micritization, bioturbation and the influence of burrowing organisms, cementation (types of cement related to marine, meteoric and burial diagenesis environments), dissolution (meteoric and burial dissolution), dolomitization (in different phases), silicification, pyritization, phosphatization, mechanical compaction, chemical compaction, fracture and porosity. Based on the identification of the sequence boundaries and following the facies depth changes, the carbonate sequence of the Asmari formation in the subsurface section and the Asmari anticline section are introduced in the form of 3 sedimentary sequences of the third order shallowing upwards, which are the former Aquitanian, the late Aquitanian and Bordigalin belong. Among the dominant porosities in the Asmari Formation, we can mention the hole, mold and fracture porosities. Manuscript profile

For this purpose, these formations were investigated using NGS well log (one well ring), X-ray diffraction method (XRD) and XRF analytical method (11 samples from two wells). In the NGS log, the detected minerals are illite, montmorillonite, mixed layer, glauconite and feldspar. In the XRD method, clay minerals illite, montmorillonite, mixed layer, chlorite and kaolinite were identified in order of abundance.These minerals due to their sensitivity to react with water causes the instability of the borehole. The high ratio of Si/Al and changes of Ti and high level of Fe3+ and Mg are also a sign of the widespread presence of illite, chlorite and montmorillonite in the mentioned formations.   <span style="font-size: 10.0pt; mso-bidi-font-size: 11.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: Calibri; mso-bidi-theme-font: major-bidi; mso-bidi-language: FA; mso-bidi-font-weight: bold;">The changes of major and trace elements compared to Al2O3 except for MnO, CaO, and P2O5 showed a positive linear relationship. The changes in the amount of Fe2O3 show the oxidizing conditions in the upper part of the base, but the reducing conditions towards the upper side. Based on the amount of iron, manganese and vanadium, the sediments were formed under conditions of reduction, non-sulphide reduction Eh and medium to low pH. Variations in Th/U ratio (1-4.5) indicate marine to transitional environments. The existence of horizons rich in organic matter (more than 2%) confirms the reduction conditions.   <span style="font-size: 10.0pt; mso-bidi-font-size: 11.0pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: Calibri; mso-bidi-theme-font: major-bidi; mso-bidi-language: FA; mso-bidi-font-weight: bold;">Based on the low values of the Zr/Rb ratio, the sediments in the upper and lower parts are finer than the middle part of the grain. The relative accumulation of biogenic carbonate along with the shale is periodic and is reflected in the changes in the (Zr+Rb)/Sr ratio. Based on the Sr/Ba ratio, marine conditions prevail in the lower part and continental and metamorphic and sometimes marine conditions prevail in the upper part of the formation. Oxidation-reduction conditions were also investigated. The values of the V/(V + Ni) ratio of the semi-reduction region, the Ni/Co ratio of the reduction region and the V/Cr diagram show the almost reduction region and in some cases the oxidant conditions. Paleoclimatic conditions at the time of sedimentation based on low values of Rb/Sr ratio (less than 0.14) were completely hot and dry.   Manuscript profile

One of the most important goals of any government and country is to achieve stability in various economic, social, financial and political fields. The present study examines the effect of oil shocks on political, financial and economic risk in Iran's economy using the framework of structural vector autoregression (SVAR) model in the period of 1379:4-1398. The results of the impulse response functions show that the positive oil price shock has led to an increase in the political risk index in the short term, which was in accordance with theoretical expectations. Also, the positive shock of the total demand has followed the positive reaction of the risk index and has led to the decrease of risk. Sanctions have recorded the greatest effect on political risk. The positive shock of oil supply and total demand has led to a significant reduction in financial risk. The economic risk also shows a significant reaction to the total demand shock and the sanctions shock, as a result of which the risk increases.The results of variance decomposition show that among the three risks (oil price, oil supply, and oil demand), oil shocks have the greatest impact on financial, political, and economic risks, respectively. Financial and economic risk had the greatest effect from the total demand shock and political risk from the oil price shock. Manuscript profile

Kupal Oil Field is one of the important oil fields in the Zagros Basin, located in the eastern part of the Dezful embayment, adjacent to Aghajari Oil Field and Marun Oil Field. Some characteristics of the fold elements, such as the fold interval angle and axial surface, were determined in the Asmari folded horizon using the interpreted seismic profiles. Based on the deviation of the axial surface from the vertical surface and determination of shear angle and shear strain, minimum and maximum quadratic stretch and strain ratio (R) values were calculated in different parts of the anticline. With application of graphical functions the amounts of fold aspect ratio were determined along the anticline. Base on the results, the amounts of shear strain varies from 0.01 to 0.09 in deferent parts of anticline. Also results show the amounts of strain ratio in range of 1.25 to 1.38 and shortening about 5% to 17% in different parts of the kupal anticline oil field. Manuscript profile
