Nowadays, due to the limitation of fossil fuels, the topic of their optimal use has been given more attention than before. In the upstream literature of oil and gas economy, the word synonymous with this topic is reservoir management. In this study, selected one of the oil fields of Iranian Offshore Oil Company (IOOC). In the first step, by using field data, the cost function of the field is estimated by considering the environmental costs and secondary recycling costs, and in the next Nowadays, due to the limitation of fossil fuels, the topic of their optimal use has been given more attention than before. In the upstream literature of the oil and gas economy, the word synonymous with this topic is reservoir management. This study selected one of the oil fields of the Iranian Offshore Oil Company (IOOC). In the first step, by using field data, the cost function of the field is estimated by considering the environmental costs and secondary recycling costs, and in the next step, the discounted profit of the field during its life under three discount rate scenarios, and it is maximized by dynamic programming method. The results of the bell curve study confirmed the production during the life of the field. Also, in the scenario of the discount rate of 5%, the harvest results from the field have been more balanced, and with the increase of the discount rate to 10 and then 20%, more harvest has been achieved in the first years of production and less harvest in the final years of productionstep, the discounted profit of the field during its life under three discount rate scenarios. and it is maximized by dynamic programming method.

The purpose of this study is to compare the economic efficiency of Iran's petroleum contracts, buyback contracts, and production-sharing contracts. This study also determined the optimum path for production and drilling operations in the Yadavaran oil field which has special importance because it is a joint field with Iraq. It was estimated using real field data and the SQP algorithm by MATLAB software. First, the objective function, the constraints of each contract model, and the cost function are defined and expressed based on field data. For the objective function, the oil price is determined based on the reference price scenario and based on the forecast of the US Energy Information Administration (EIA). Cao et al (2009) 's cost function model is also modified by using historical field data (first development phase data) to be applied to the study field. The results show that the most efficient oil contract is the Iran petroleum contract, with a low floor for capital costs and no limit to the number of drilled wells. it was proved that the buyback contract with the ceiling of capital costs incompatible with the recovery coefficient has recorded the lowest efficiency. Also, the Iran petroleum contract can be a good alternative to the buyback contract, because it can well solve the problems of the buyback contract, especially for joint oil fields where the priority of the objective function of the maximum cumulative production over the objective function of the maximum present value of the total profit is more desirable.

The act of planning in order to reach optimum production from crude oil reserves with emphasizing on technical limitations and economic modeling and forecasting, is known as a necessity to earn the maximum profit from oil export incomes and providing national intertemporal interests for oil producing and exporting countries. This study estimates the optimal trend of crude oil production from south Azadegan Iranian oil field by the metaheuristic algorithm of Particle Swarm Optimization (PSO) on a thirty-year period. The concept of maximum efficient rate (MER) is employed to reach the best simulation of technical and physical field properties and moreover, the three price scenarios and two discount rate scenarios are used to apply the economic dynamics of crude oil world market. The results show that applying EOR programs simultaneously during the production by gas injection into the anticline of SARVAK reservoir, proven reserve of the field can be increased up to 6 billion barrels in this period. It also increases the cumulative production up to 3 billion barrels during the simulation period which was about 1.4 billion barrels based on the present RMDP
