.... Using reservoir simulation, it is a common practice to calculate a well cash flow using only the fluid production. If all of the costs and gains could be associated with oil and water production, it would be possible to find a relation between water cut and well cash flow. Thus, a water-cut limit could...

Because of the contrast properties of different layers, the water cut phenomenon is relatively fast and severe which hampers the productivity and ultimate recovery of the individual well as well as the field. For effective Reservoir Management and to limit the declining trend of the field, Water...
