Common field oil recovery had been a priority for political and governance reasons. This priority is included in the upstream policies of the country. EOR methods are implemented to increase the recovery factor on production zone. In addition to the technical factors of field development, the financing aspects of the development is also an effective factor in the progress. One of the most important effective factor in financing aspect of IOR/ EOR is financial system of oil contracts. The current research was performed on a simulated model of a field in the Southwest of Iran, with the variables of oil production and gas injection rates the perforation interval, and the location of new wells. The cumulative production and oil migration in the reservoir were investigated as optimization functions. The optimization of these variables to achieve the desired technical functions has been done with NSGA-II evolutionary algorithm. After obtaining a set of equivalent optimal answers (Pareto front), Net present value and government financial income as economical functions were investigated in three financial models of the BuyBack, Production Share Contract and Iran Petroleum Contracts.
After optimization process of the technical objective functions, a hundred different scenarios have been proposed. After the technical and financial investigations and comparison between the three contracts, it was found that the current net value of Iran Petroleum Contracts was higher than the other two types of contracts. Also, the final financial income of the field has generally decreased from the scenarios with emphasis on cumulative production to the scenarios with emphasis on less migration. BuyBack contract, the net present value is independent of technical functions and has not changed with the change of technical variables in different scenarios. The other two types of contracts produced different net present value and The government's earnings on different condition.
