The present research has been conducted with the aim of the pathology of conservation in the production of the Parsi oil field and providing solutions for improved maintenance production process. For this purpose, using the SWOT approach and analyzing the information collected from the questionnaires was completed by experts and specialists of the National Iranian Oil Company in 1400. The results indicate that the production conditions of protection in the situation of conservative strategies are based on the final scores of the internal and external factors of the SWOT matrix, which are 1.988 and 2.67, respectively. Also, the results show that the expertise and efficiency of the workforce and the existence of knowledge and technology required to use reservoir-based overdraft methods with scores of 0.24 and 0.177, respectively, are the most important strengths. Moreover, lack of principle of safe production in practice due to reasons and lack of comprehensive and specialized planning in accordance with the goals of safe production to convert potential oil into actual at the ministry level with scores of 0.063 and 0.062, respectively, have been identified as the most important weaknesses. In addition, the support of upstream documents on the conservation in the production and the nationality of the NISOC with scores of 0.228 and 0.224, respectively were identified as important opportunities. It should be noted that the existence of restrictive regulations and programs of the Ministry and the existence of some anti-conservation in the production of oil contracts with scores of 0.057 and 0.056, respectively, are the main threats. Therefore, the existence of integrated management with a focus on the conservation in production and attention to internal and external factors could improve the conservation in the production process.

Due to the problems and limitations of using fossil energy sources, the use of biofuels in order to achieve the goals of sustainable development, reducing greenhouse gas emissions, regional development, and security of energy supply, has received more attention. Therefore, considering the importance of the issue, in the present study, while determining the effective factors on the tendency of farmers to accept the supply of crop residues of wheat and barley products for bioenergy production, the economic value of residues of selected products in biogas and bioethanol energy production is estimated. Accordingly, using a survey approach and by completing a questionnaire by farmers in Boroujerd in 1399, data collection and research hypotheses were tested using the logit regression model. The results of the study indicate that the variables of collection cost (with a final effect of -0.097 and elasticity of -7.39%), non-agricultural income (with a final effect of -0.028 and elasticity of -6.37%), and use from residues (with a final effect of -0.014 and a tensile strength of -11.6%) have a negative effect on the supply of agricultural residues for bioenergy production. Meanwhile, education (with a final effect of 0.09 and elasticity of 4.4%) and farmer experience (with a final effect of 0.022 and elasticity of 17.32%) have a positive effect on the supply of agricultural residues for bioenergy production. According to the results of traction, farmers' experience and farmers' use of agricultural residues have the greatest effect on the supply of agricultural residues in bioenergy production. The results also show that the annual production potential of bioethanol from wheat and barley residues is equal to 63.96 million liters. So that if the same residues are used in biogas production, the annual biogas production potential is equal to 88.98 million cubic meters. Accordingly, the economic value of bioethanol and biogas energy production from wheat and barley residues in the study area has been calculated equal to 15349 and 430 billion rials, respectively. Therefore, based on the results, by planning for the principled management of agricultural residues and investing in the use of biomass as clean sources for bioenergy production, effective measures can be taken to reduce the dependence of the country's economy on fossil energy and provide the energy needs of people in remote areas.

Development of renewable energy would help to achieve the goals of economic, social and ecological development which are considered as the most important factors in achieving sustainable development in each country. This article examines the impact of real economic growth per capita on the country's clean energy deals during the period 1967-2012 in Iran. To this end, the pattern Auto Regressive Distributed Lag (ARDL) and Co-Integration method are employed to determine the presence of short and long-term relations among the variables. The results show that the speed of adjustment is relatively high error correction model and the model is able to adjust the 61% of short-term imbalance error, to achieve long-run equilibrium. According to the corresponding estimations, the relationship between real economic growth per capita and renewable energy consumption, combustible renewable and waste consumption and electrical energy consumption in both short-term and long-term is negative. Also Long-term results have showed a significant negative relationship between electrical energy consumption, renewable energy consumption combustible renewable and waste consumption and real economic growth per capita. So, in long- term, increasing one percent consumption of the mentioned variables, cause to decrease the real economic growth per capita to 0.71, 0.72 and 0.79 respectively.
