Abstract: Water drive curve methods of A, B, C and D types are usually used to predict recoverable reserves and recovery factor in water drive oilfields.However, some researchers considered that A,B, C and D types water drive curve method are suitable for oilfields with different formation oil viscosities.The study of this paper indicated that there is no directly relations between different formation oil viscosities and the selection of water drive curve methods.
