Abstract: The oilfield evaluated the economic performance of a single well in order to make a reasonable plan for production targets and optimize the oilfield production. Based on the economic characteristics of the oilfield production, the profit production is divided into the profits from new wells, old wells and stimulation measures. The method for calculation of a new well’s profit production is cash flow method, which takes a new well as a construction project and evaluates its economic performance. It is focused on construction scale of productivity and the new well’s production of the year at the time of net present value. The method for calculation of an old well’s profit production is single-well contribution value method, which evaluates the contribution to the economic performance of the oilfield from a single well’s revenue with the changing cost deducted. It is focused on the old well’s production at the time of its maximum profit. The research method for economic production from the stimulation measures is based on the input-output model to evaluate the economic performance of additional value from the stimulation measures. It is focused on the stimulated production at the time of maximum profit. This paper comes up with the calculation models of the oilfield profit production for new wells, old wells and stimulation measures. Those models help the oilfield bring about good economic performance of production, solving the problem that the oilfield only focuses on production target while neglecting the economic results in its production plan.
