Study on the Economic Evaluation Method of Single Well in Overseas Oil Field Under the Model of Production Enhancement Service Contract

The oilfield production enhancement service contract, mainly for international petroleum engineering technology service companies, is a production service contract introduced into the oilfield engineering technology service contract, in which the contractor bears the production risk, engineering and construction cost, and oil price change risk, while receiving the corresponding return. This paper addresses the characteristics of the oilfield production enhancement service contract model, and establishes an evaluation model for the economic limit production of a single well and the limit investment of a single well under this contract model based on the cash flow method and multiple regression analysis, which provides better decision support for efficiency development, production and operation strategy decision and programme investment optimization. There are many factors affecting the profitability of overseas projects. On the one hand, it can promote the optimization of programme investment deployment and production operation; on the other hand, it can guide the geological reservoir technology research, and the single well production allocation can be continuously adjusted according to the international oil price changes during the project execution to achieve project profitability.
