Organizational ambidexterity refers to the ability of organizations to perform conflicting and contradictory activities. This concept is important in innovative technology-based organizations, because these organizations need to combine creativity and innovation with efficiency and productivity. As a technology-based organization, ACECR needs a duality to commercialize its innovative products and services. The aim of the current research is to design an ambidexterity development model of technology-oriented organizations to commercialize innovative products.

The research strategy is based on foundational data theorizing, and the data analysis method of the current research is the Strauss and Corbin’s systematic method (systematic model), and the data collection was done with the interview tool. In the qualitative phase, 16 interviews were conducted with the experts of technological organizations of ACECR and four additional interviews were also conducted to achieve theoretical saturation. In the quantitative phase, the descriptive-survey research method was used, and in this phase, the data collection tool was a questionnaire.

Organizational ambidexterity management has been identified as a central category in this research, and its subcategory concepts include ambidexterity structure management, innovative culture management, and ambidexterity process management, which constitute the central category. The causal conditions in this research include ambidexterity management and leadership, ambidextrous human resources are multifaceted structures. On the other hand, the bases include organizational ambidextrous culture, upstream documents, and Jihadi culture. Also, the strategies resulting from the foundation's data theorizing model include designing two-way human resources processes, designing a technology commercialization model, designing an organizational two-way evaluation system, and designing a resource allocation system. On the other hand, institutional communication in the field of science and technology and the environment of organizational ambivalence as intervening and ultimately value-creating factors, completing the technology chain, organizational development, and management of organizational contradictions, the consequences of identifying and explaining the factors affecting organizational ambidexterity in the direction of commercialization which have been in technology-based organizations.

The management of organizational ambidexterity plays a significant role in the success of commercialization of technology-based organizations. Management of structure, culture, and dual processes are key factors affecting organizational duality. Also, conditions such as ambidextrous management and leadership, ambidextrous human resources and multifaceted structures affect this process. Consequently, it is suggested that organizations focus on strategies such as the design of dual commercialization processes and models to provide the necessary ground to achieve duality and successful commercialization. It is necessary to conduct more studies in this area.

Iran is one of the largest resource-oriented countries and the owner of oil and gas reserves in the world; However, the technological gap in Iran's oil industry with global companies and little attention to the development of domestic capabilities for exploration and production and manufacturing of upstream equipment and products of the oil industry has led to a low share of supply of equipment and machinery for upstream oil industries from within and excessive dependence on outside.In this research, first, by reviewing the literature with a macro view of natural resources including oil and gas in the process of economic development, the factors affecting the technological capabilities of the supplier companies were calculated.By using this conceptual framework, the interview questions were set and after conducting research interviews and analyzing it with thematic analysis method, the final model of the factors influencing the promotion of technological capabilities, which includes learning and innovation, financing, technology development strategy, and human resources, is included. The primary influencing factors at the enterprise level and government policies, the plans of exploration and production companies, hard and soft infrastructures, and the evaluation and rating system of suppliers are the influential factors at the macro level, identified and presented in domestic suppliers of equipment for Iran's upstream oil industries(pump manufacturers).

During the last century, Iran has made many efforts to transfer technology through oil companies, but it has been less successful in this field. One of the reasons for this lack of success can be found in the absorption capacity of oil companies in accepting transferred technologies. The aim of the current research is to analyze the impact of technology transfer methods on improving the absorption capacity of oil companies using a descriptive-survey method. For this purpose, while fully examining the effective criteria on absorption capacity in technology transfer methods, the status of technology transfer methods in Iran's exploration and production companies was surveyed from this point of view. The statistical population of this research was made up of all the experts and specialists in the field of technology management and oil and gas field, 31 of them were selected by the purposeful sampling method, and a researcher-made questionnaire was used to collect information, and the t-test was used to analyze the data. . The results indicate that relying on 20 selected criteria of absorption capacity and examining more than 23 cooperation methods among Iranian companies, 15 cooperation methods have had the greatest impact on absorption capacity in Iranian companies. In this regard, policy approaches were also presented.

Deficiencies of Environmental Regulations on Mine Exploration Law in IranAbstract A legal response to the environmental threats caused by mine exploration cannot be achieved without identification of such special threats. For the same reason, the geological studies of the environmental threats caused by mine exploration are an essential step for such a legal response by codifying appropriate rules and regulations and developing a proper legal system. This article is to, initially, identify and classify the environmental threats caused by mine exploration and then to identify and evaluate legal gaps and challenges in Iranian legal system to deal with such threats, by using the analytical method.What are the deficiencies of environmental regulations on mine exploration in Iranian legal system and what is the strategy to tackle such deficiencies? The environmental threats caused by mine exploration is identified in a very general, partial and imperfect manner in Iranian legal system. Missing details and lack of classification of threats in terms of the mine and the practical problems in this area, are some definite challenges in this domain, which in turn have seriously impeded the effective legal response.

In order to assess the risk of exploration and development of oil and gas fields, which is mentioned as one of the ‎most important determining parameters in the economic development of oil- countries, an expert system using ‎the inference fuzzy system approach was designed. First, the system inputs, which are in fact the characteristics ‎of risk assessment for the exploration and development of oil and gas fields, were extracted. In continuation, ‎the knowledge base of the system, the most important part of which is considered to be in the form of if-then ‎rules and based on the opinions of experts in the upstream part of the oil industry. To do this, the degree of ‎system accuracy is measured in two stages based on expert comments. Based on the Likert scale and presenting ‎a questionnaire to the experts, Student's t-test was performed and out of 48 defined indicators, 42 indicators ‎were selected as the final index. In the next step, the data validation of an oil field in the south of the country ‎was provided to the oil industry experts and they were asked to evaluate the output of the system‏.‏‎ Finally, the ‎opinions of experts were compared with the output of the expert system and based on the criterion of mean ‎square error (MSE) and a small difference between the average opinion of experts and the output of the system, ‎it was determined that the designed expert system has sufficient accuracy and validity for future studies.‎

A review of empirical studies in the field of insurance of upstream oil and gas projects suggests that domestic insurance companies and insurance consortiums in Iran rely on the experience of reinsurance companies to determine premiums and risk conditions. Given the economic sanctions and restrictions on determining precise premiums and conditions for direct insurance and reinsurance of oil assets, it is necessary to establish a method to determine premiums even under normal circumstances that can be referred to international reinsurers. To address this need, the present study adopted an empirical method that uses risk-based valuation and the monetary value at risk (VaR), which covers a wide range of relevant oil and energy insurance aspects. The results showed that the research method can determine the premium of oil assets following international standards, taking into account expert opinions and other domestic considerations.IntroductionOil and gas continue to be among the primary sources of energy globally, hence a crucial and fundamental part of the world economy. The various sectors within this vast field offer significant capacities and resources at a large scale, including research, equipment, and resources for exploration, development, and utilization, as well as the derivatives in the real sector processes. In addition, transportation, exchanges, transactions, physical markets, and stock exchanges also play a significant role in this industry. The world economy is thus highly dependent, both directly and indirectly, on the oil and gas industry. It is evident that the global oil and gas industry involves a vast amount of capital and risk, which is more complex and extensive than one may imagine. The industry interacts with numerous sectors of the economy, with extensive links that exceed beyond a single field. Considering the relatively small share of oil and energy insurance in the portfolio of the insurance industry, there are various factors that prevent the entry of insurance services into this area on a significant scale. One significant obstacle is the lack of scientific studies on determining the value at risk for oil assets, which is a crucial factor in determining the volume and size of insurance premiums for insurable oil and gas assets. Using the valuation and estimation of monetary VaR of oil assets, the present study aimed to develop a method for insurance companies to determine the insurance premium of oil and gas assets. An example was provided to demonstrate the applicability of the proposed method in practice. Materials and MethodsTo conduct a risk-based valuation, the study employed Smith’s method as well as the method proposed by Knapp and Heij in order to estimate the value at risk for oil assets.The NPV for the valuation model of exploration and development risk will be as follows (Smith, 2004): (1)Where CF0 is the drilling cost,  is the probability of a failed well and {CF1, CF2... CFr} are the expected cash flows in case of success of the well and (i) is the discount rate.According to Knapp and Heij (2017), identifying risk factors, which are variables that pose a risk for an oil asset, is crucial in estimating the value at risk. The risk factors are evaluated based on their probability of occurrence.The monetary VaR is estimated based on the insurable value of a physical asset, which is typically the replacement cost or the actual cash value of the asset covered by standard insurance policies.To estimate the value at risk, two probabilities are combined, which are determined based on the total insurable value (TIV). For instance, if there are five risk groups denoted as j (j=1,...,5), vj represents the sum of the insurable value for each type. TIV is defined as the total of all five groups, as follows:            Furthermore, Pinc represents the probability of an event occurring within a year. Pj is the conditional probability of damage in group j occurring in relation to a particular event. Then monetary VaR is then defined as follows: (2)It is important to note that TIV is derived from the method proposed by Smith (2004), which can be used to assess the value of the entire property or its individual parts and components.The insurance rate and premium can be estimated on the basis of the model of exploration and development risk, along with the future discount rate. This estimation includes the initial cost (drilling or installation cost) CF0 and is given by the following equation:NPV, in Relation (1), is replaced by the future value (FV) or the total insurable value (TIV) of the oil asset.CFt = CF0: NPV is equivalent to book value or price determined by official experts or official pricing authorities.PDH: Probability of occurrence of major risks, which is considered equivalent to catastrophic risks leading to total damage.i: It represents risk insurance premium, which is equivalent to the probability of the occurrence of conventional risks that each oil asset faces according to its specific conditions.Now Relation (1) will be changed to Relation (3):  (3)Now monetary VaR is calculated as follows: (4)In equation (4), V is TIV, which is equivalent to FV calculated based on Relation (2).Results and DiscussionThe study used the information on the insurance policy of HP-2000 drilling rig of North Drilling Company.               Table 1 Information on the HP-2000 drilling rigThe value of the drilling rigReinsurance premium rateMarket premium rateInsurance premium12000.0040.00283.4(billion rials)  (million rials)* Source: issued insurance policyThe future value of the drilling rig for one year is described in the following table:Table 2 The future value of the drilling rigNPV iFV12000.00220.0032400(billion rials)  (billion rials)* Source: research resultsThe monetary VaR based on the future value at risk (FV), which is equivalent TIV, for the insured drilling rig is as follows according to Relation (2):Table 3 The monetary VaR of the drilling rigFV=TIV  MVR24000.00220.84.3(billion rials)  (million rials)* Source: research resultCatastrophe risk (Pinc) and the 5-fold decomposed risks of the oil rig are determined based on expert opinion, which will be the basis of monetary VaR estimation.The premium values ​​and the rate calculated based on the monetary VaR were compared to the premium values ​​in both cases of reinsurance and market (Table 4). Premium rate is obtained by dividing premium, which in the proposed methods is equal to Monetary VaR (MVR), by oil rig price.Table 4 Comparison of the insurance premium rate based on the MVR method with the reinsurance and market rateMVR rateReinsurance rateMarket rate0.00350.0040.0028* Source: research resultsConclusionThe present study highlighted the characteristics and significance of the oil, gas, and petrochemical industry within the global economy, emphasizing the extensive interactions of this industry with various sectors of the economy, particularly in the field of insurance.The study used a distinctively innovative methodology which combines Smith’s (2004) risk valuation of oil assets with Knapp and Heij’s (2012; 2017) monetary VaR approach to determine the insurance premium rate. The proposed research method allows for the determination of an insurance premium rate that is equivalent to international reinsurance rates, based on the factual, environmental, and market conditions. The study offers insurance and oil engineering experts the possibility of calculating an appropriate insurance premium rate for an oil project based on the identified risks using empirical and technical knowledge, as considered in the proposed method.

The aim of the present study was to compare the effectiveness of group exploratory and conceptual learning in science lessons on the academic self-efficacy of male students.

The current research was applied in terms of its purpose and in terms of its implementation, it was a semi-experimental research with a pre-test-post-test-follow-up design with a control group. The statistical population of this research was the fifth grade male students of Kiyar city in the academic year of 2020-21. The research sample consisted of 75 male students in three experimental groups of exploration, concept learning and control (25 people in each group) who were selected by multi-stage cluster random sampling from 3 schools and 3 classes. The research tool was the self-efficacy questionnaire of Jenkins and Morgan (1999) and the intervention was the method of exploratory group training and concept learning group training for 10 sessions (each session 45 minutes) which was implemented for both experimental groups. For data analysis, inferential statistical methods (repeated measurement analysis and Benferroni post hoc test) were used with Spss24 software.

The results showed that both exploratory group training and conceptual learning increased academic self-efficacy scores compared to the control group. But there was no significant difference between the average scores of exploratory group training and conceptual learning. In other words, both methods of exploratory group training and concept learning group training equally increased academic self-efficacy scores (P<0.05).

Based on the findings, it can be concluded that the group teaching of exploration and conceptual learning increases the academic self-efficacy of students in the science course. Therefore, lesson planners can pay more attention to these methods and also elementary school teachers can use these educational methods in teaching science lessons to better understand students and their academic self-efficacy.

We are facing an increasing number of studies related to the concept of the brand, especially the brand image and the concepts derived from it. As a gap, there are some conflicting contents extracted around this concept that motivated and prompted the researcher to do a systematic review based on the ADO framework in this field to classify, consolidate and integrate the results of the findings of other authors and to explain the integrated concept of brand image, its antecedents, and outcomes.  Therefore, based on the four-step pattern of systematic review qualitative research method, a search plan for articles in valid databases was developed.In the next step, the best articles that were considered qualified according to the main research question were downloaded, selected, screened, and evaluated for deeper investigations and findings for the appropriate answer to the research question. In this process, 33 eligible articles were selected for the final evaluation. The research findings from previous studies show that the focal construct of brand image includes at least 53 codes as antecedents and 20 codes as outcomes. These codes are classified as a conceptual model in the form of six cognitive, perceptual-attitudinal, sensory, emotional, communicative, and behavioral dimensions at different levels such as customer level, organization level, national level, and transnational level. As a result, an empirical test of the proposed model is suggested to future researchers.

The present study was conducted by combining previous research with the aim of providing a comprehensive picture of the paradoxes arising from pursuing ambidexterity as an organizational strategy.

The research methodology is qualitative with a meta- synthesis approach. Exploring studies related to ambidexterity paradoxes, 223 studies were evaluated and finally, after multiple screenings of the studies, 45 articles were selected.

With the help of coding method, 67 codes, 12 concepts and 4 components were identified and validated through Kappa Cohen coefficient. Using seven-step model of Sandelowski and Barroso, the findings of 44 previous studies related to the objectives of the study were reviewed, aggregated, combined and interpreted.

According to the results, paradoxes emerging from pursuing ambidexterity are bundled in four different categories of paradoxes including paradoxes resulted from stakeholders’ interest, paradoxes resulted from control maintenance, paradoxes resulted from resources limitation, paradoxes resulted from innovation system inefficiency.

So an organization needs strategic ambidexterity and consequently Increasing the efficiency and productivity of companies in order to survive, grow, Performance improvements, Product-service innovation, and the Possibility of competitiveness in today's dynamic environment. To maximize firm’s performance, Product-service innovation must be developed through a sequential Exploitation-Exploration pathway. To do so, initially, reviewing the literature, the conceptual model of this study was extracted, and then in order to analyze the research model and hypotheses, we examined 333 industrial firms in Isfahan city. For the validity of this questionnaire, the comments of professors and experts were used. For reliability, Cronbach's alpha was used and its value was determined to be 0.941. Path analysis method was used to analyze the data. According to the research model, data analysis indicates the existence of a positive and significant effect of exploitation and exploration on performance through product and service innovation and the mediating role of exploration in the impact of exploitation on performance Also, there is a positive and significant effect of exploitation activities in manufacturing companies developing product and service innovation on exploration activities and a positive and significant effect of product and service innovation on performance. The results showed that there is an optimal sequential Exploitation Exploration pathway in product and service innovation and exploitation-exploration pathway and the path to achieving profitable product and service innovation begins with the use of existing resources and capabilities of the firm and is followed by exploration to determine and develop appropriate technological applications.

The information asymmetry between the National Iranian Oil Company and the companies applying to enter into oil and gas development contracts is the cause of the phenomenon of adverse selection in those contracts. This study seeks to answer this question: what are the legal and contractual solutions for managing risks due to adverse selection, and whether the selection process of exploration and production companies guarantees the prevention of adverse selection or not. For this purpose, the findings of economics have been used in the framework of the adverse selection model with the aim of identifying legal and contractual tools to manage these risks. Examination of the evaluation processes of exploration and production companies indicates that the methods adopted for the evaluation and screening of applicants are not sufficient and this process can be considered as an example of adverse selection e. In this regard, designing and establishing a comprehensive contractor evaluation system, assigning the evaluation of financial capacity of contractors to credit rating agencies and using the capacity of contractual conditions to implement signaling and screening patterns are some of the strategies that can minimize client risks relevant to adverse selection.

There are many teaching patterns, groupings and variations. that a teacher can use one of the models or a combination of different models to choose his teaching method based on the conditions, situation, age levels, capabilities of the learners and teaching subject. The purpose of this article is to provide a unified method using pre-organizing and exploratory patterns for elementary school students.

The research method is documentary, and by using the tool of taking a nots and checklist, the necessary information has been collected, conclused and synthesized.

The findings of the research show that by combining the exploratory model and the pre-organizing model, a model can be obtained that can lead to an increase in students' research skills by using beta and gamma waves, in addition to increasing knowledge.

From the combination of two pre-organizing and exploratory models, a model has been obtained that can be effective in the academic progress and scientific and personal development of students.

Despite the increase of empirical studies on the organizational ambiguity phenomenon, which is the discovery of new opportunities while exploiting existing competencies, in entrepreneurship and management literatures, there is little knowledge about the factors affecting the formation of ambidextrous behaviors of employees in organisaions. The present study examines the relationship between individual entrepreneurial orientation and ethical behavior and contextual ambidexterity. This research is applied in terms of purpose and descriptive in terms of data collection method. Based on the questionnaire, the data were collected from 203 employees of food industry businesses in Tehran and analyzed with SmartPLS software. The research results show that entrepreneurial and ethical orientations increase individual ambidexterity, yet the moderating effect of ethics on the relationship between entrepreneurial orientation and individual ambidexterity has not been confirmed. These results suggest that exploratory behaviors, while performing daily tasks, can be expected from the employees who are more entrepreneurial and ethical.

Abstract
The present study was conducted to design an employee behavioral ambidexterity model in knowledge-based companies. It used a qualitative research method based on the systematic Grounded Theory. The sampling was done theoretically and using purposive and snowball techniques, based on which semi-structured interviews were conducted with the experienced managers and senior experts of knowledge-based companies and academic elites in the field of health. To ensure the reliability and validity of the interviews, the researchers reviewed the previous studies, took advantage of the opinions of experts in all stages and processes of this study, and used three strategies developed by Creswell and Miller. The results of the analysis of the data obtained from the interviews during the open, axial and selective coding process led to the development of the Grounded Theory in the field of employee behavioral ambidexterity for knowledge-based companies.

Employees have the most important role in knowledge-based development. According to researchers, it is the employees of the organization who make it possible to apply ambidexterity at the organization level through their ambidextrous behavior. Employee ambidexterity is thus defined as a behavioral approach in employees that is performed by combining activities related to exploitation and exploration in a certain period of time.
Recent studies have shown that simultaneous exploration and exploitation in a business unit is also a prerequisite for its success, especially in high-tech companies such as knowledge-based companies, which strongly rely on innovation as a competitive source. In the field of health, these companies encounter the dual demands of exploring new products/processes while simultaneously exploiting the existing products/processes. Therefore, through their employees, companies should simultaneously exploit the existing competitive advantage and explore new projects with equal skills.
Case study
The statistical population of the present study consisted of experts (including managers and experienced senior experts) and academic elites (including experienced professors of management) in the knowledge-based companies of the field of health in Tehran province.
Theoretical framework
Employee ambidexterity is defined as the behavioral orientation of employees to combine exploration and exploitation activities in a certain period of time. Exploration is defined as experiment-related behaviors, looking for alternative ways of doing something, and learning from mistakes, while exploitation is defined as "relying on previous experiences, carrying out everything, and gradually improving the learned actions".
To pursue both strategies (exploration and exploitation), ambidextrous organizations need employees who are capable of implementing both in the organization. Ambidextrous individuals can effectively use the opportunities available to them and simultaneously use all their available power and capacity to perform current affairs and overcome the existing challenges. Therefore, organizational ambidexterity requires having human resources capable of ambidextrous behaviors. In theory, researchers have argued that in order to have an appropriate level of ambidexterity, employees must be able to perform exploration and exploitation simultaneously. Schnellbächer & Heidenreich (2020) investigated the role of individual ambidexterity for organizational performance and found that ambidextrous knowledge offering leads to higher performance effects in environments characterized by the pursuit of radical innovations, while ambidextrous knowledge seeking is rather suited for environments with a focus on innovating incrementally.

The dominant paradigm of the present study is the interpretive paradigm and the strategy used in it is the Grounded Theory based on the systematic design of Strauss and Corbin (1990). Semi-structured interviews were conducted with 21 experienced managers and senior experts and academic elites in knowledge-based companies in the field of health. Each interview lasted from 45 minutes to one hour. From the 18th interview onwards, the data analysis did not lead to discovering new concepts and categories. However, three more interviews were conducted to ensure theoretical saturation.
Discussion and

After conducting and implementing the interviews, the interviewed texts were analyzed using the Grounded Theory strategy in three stages of open, axial and selective coding. Based on the analysis of the interviews, 19 categories and 60 concepts were identified and extracted from the coding process. Finally, based on the systematic approach in the Grounded Theory, the identified codes were divided in six categories, including causal conditions, ground conditions, intervening conditions, strategies and consequences around the axial category of "competence of exploration and exploitation". The four categories of spirit strengthening, internal motivation, attitude/behavior/perception, and skills were identified as the causal conditions of behavioral ambidexterity of employees in the studied organization. Development of the organization’s nature of work, legal-ethical requirements, learning and development, leadership requirements and external motivation were identified as the underlying factors, while psychological security and environmental security were identified as the intervening factors. Enhancing the culture of empowerment, accepting the culture of knowledge sharing, integration and coherence, and managing the flow of knowledge and information were identified as effective strategies which can lead to innovative behavior and performance and high job satisfaction (positive outcomes) and stressors (negative consequences).

Various studies on ambidexterity show that organizations that become ambidextrous, i.e. successful in exploitation and exploration capabilities, will perform better in dynamic environments and achieve the highest level of performance, competitiveness and long-term survival. This study was conducted using the Grounded Theory research method with the help of open, selective and axial coding. The data analysis process led to the creation of a theoretical model that includes causal conditions, contextual conditions, intervening conditions, strategies and consequences that explain the main phenomenon, namely, "competency of exploration and exploitation".

The aim of the present study is to investigate the role of motivational factors and personal characteristics on sharing of unconfirmed information by mediating social media fatigue in the time of COVID 19. This study is an applied study in terms of purpose and is a type of descriptive-correlational studies in terms of data collection method. Statistical population of the study consisted of all students at Semnan University in the academic year 2020-2021 that 230 people were selected as sample by stratified random sampling method. Study instrument included personal characteristics (Khalaf & et al., 2014), motivational factors (Islam & et al, 2020), social media fatigue (Islam & et al, 2020) and sharing of unconfirmed information (Laato & et al, 2020) questionnaires. Reliability of questionnaires using Cronbach's alpha, was respectively (0.91); (0.87); (0.70); (0.81). The results showed that Exploration, religiosity and poor self-regulation have no significant effect on sharing of unconfirmed information. Usage of social networks for entertainment and self-promotion has a significant impact on sharing of unconfirmed information and social media fatigue. Social media fatigue has a significant impact on sharing of unconfirmed information. Exploration, religiosity, poor self-regulation, entertainment, self-promotion have an indirect effect on sharing of unconfirmed information of social networks through mediation of social media fatigue. The results indicate the importance of the role of motivational factors in social media fatigue and consequently sharing of unconfirmed information of social networks.

Ministry of Petroleum of Iran predicted a competent Iranian partner for cooperating with the International Oil Company (IOC) in Article 4 of the Council of Ministers Resolution. The reasons stated as empowerment of Iranian companies for executing local mega projects, regional and international markets presence, and upgrading national technology in the petroleum upstream industry. In this regard and based on the procedure of qualification method of exploration, development and production companies of petroleum fields, seventeen Iranian companies were qualified as Exploration & Production (E&P) companies. Now that IOCs have left the Iranian petroleum market, are there still legal restrictions on the use of other contractual models for Iranian oil companies? The purpose of this study is to investigate the possibility of using Concession contracts by an E&P company. The research method is descriptive and analytical. Governing laws of Iran are reviewed in this study. Since Iran’s government makes the final decision on the conduct of oil operations, it cannot be described as the domination of oil resources, and therefore does not seriously contradict the Articles 43 and 153 of Iran’s Constitution. Furthermore, E&P companies will not be subject to Article 81 of the Constitution. In Article 6 of the Oil Law, the only restriction on the inflow of foreign capital in the upstream industry of Iran has been observed, which again does not apply to E&P companies. Finally, the results show that there are no major legal barriers to applying Concession agreement in case that the operator is an Iranian E&P company.

In the implementation of upstream oil and gas projects, the proceeds from the oil contracts are the most important asset of an exploration and production company. With an oil contract, the exploration and production company will generally be entitled to receive oil or natural gas. One of the favorable financing strategies and tailored to the conditions of upstream oil and gas projects is the use of oil and gas pre -sale contracts or the issuance of oil securities. One of the most common contracts in the world is Volume Production Payment (VPP). In this study, it was specified in an analytical way that the VPP method is not available from the jurisprudential and legal perspective, but the contractor or project company as the second party to the contract and on the basis of long -term oil sales contracts that are joined by the IPC contract. They can sell oil or natural gas for their financing. Oil and gas pre -sale in the exploration phase and the commercial uncertainty of the field is restricted.
