Comparison of the Optimal Production Path of Buy Back and Production Sharing Contracts: A Case Study of Foruzan Oil Field

Abstract

In this study, the optimum oil production pattern from the Frouzan oil field is extracted and compared using the generalized reduced gradient (GRG) optimal control method in the framework of Buy Back contract in the form of a scenario and the framework of the Production Sharing Contract in terms of different amounts of profit oil ratio in the three scenarios. Comparing the optimal route of oil production from the field in the framework of these two contracts, it is concluded that the annual production level and cumulative production will increase by increasing the ratio of profit oil and subsequently increasing the share of the contractor (or foreign oil company) as the operator of the production sharing contract. The optimum increases from the Forouzan field and by increasing the mentioned ratio from a threshold value, it is even higher than the level of annual production and optimal accumulation of the Buy-Back contract.
