Theoretical study of water saturation in oil-water fluid flow area is meaningful to the high, stabilized production and the improvement of ultimate recovery. At present, there is no theoretical description of water saturation in the oil and water seepage process. Combining relational expression between relative permeability and water saturation with the fractional flow equation produces an expression of water cut changed by water saturation; Introducing Taylor expansion and Vieta's theorem to the differentiation of water cut gives a theoretical expression of water saturation in oilwater fluid flow area; Possibility of continuity of the water saturation is also discussed. Applying this formula to certain sandstone reservoir in China achieves good results: In oil-water seepage process, water saturation is continuous in certain interval and the values of it are double in another interval; the oil recovery can be re-calculated and improved with this new equation. This new water saturation equation lays a base for the study of residual oil mobility and enhanced oil recovery.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
