Compared to conventional oil reservoirs, predicting single well EUR in shale oil reservoirs is more difficult. There are several types of EUR prediction for shale gas reservoirs, namely static method, empirical method, analytical method, numerical simulation, and probability method. The static method and probability method are generally applied in the evaluation stage when production data has not yet been obtained. After the shale gas reservoirs are put into development, dynamic methods such as empirical methods, analytical methods, and reservoir numerical simulation are generally recommended for EUR prediction. In order to predict the single well EUR of shale oil accurately, reasonably, and quickly, it is necessary to clarify the applicability of various reserve evaluation methods for shale oil, establish a standardized shale oil reserve evaluation process, and provide a basis for achieving shale oil development benefits.
