Derivation, Comparison and Application of Forecasting Water Drive Volume Sweep Efficiency Methods with Comments on Hu GangsNew Method

Abstract

Abstract: The definition of water drive volume sweep factor is the ratio of natural water drive or artificial waterflooding occupied volume and oil pore volume. Water drive volume sweep factor is the important base for judging waterflooding development effect and EOR. The method for forecasting water drive volume sweep factor methods by Type?C and Type?D water drive curves has received attention and application in practice, while there still no related method by Type?A and Type?B water drive curves recommended by the petroleum industry standard and applied universally in China. This paper proposes the forecasting water drive volume sweep factor methods through Type?A and Type?B water drive curves based on the study of related literatures. The applied examples show that the water drive volume sweep factors predicted by Type?A, Type?B, Type?C and Type?D water drive curves have the very good consistency. The derivation from the "new method" given by Hu Gang is wrong, so, it is necessary to be corrected
