Saturation Evaluation Following Water Flooding
Abstract/Contents
- Abstract
- We consider the case of a multilayer sandstone reservoir that has been under a water flooding program. Injection was balanced in all intervals. Considerable effort is required to evaluate and locate undisplaced oil that was left in the reservoir. It is difficult to find the value of the water saturation by logging because the salinity and temperature of the flood water is different from the original formation conditions. Thus, coring and other expensive operations are required to determine water saturation, and hence estimate oil saturation.The method found in this study can be used to produce estimates of water saturation using logs from initial wells and from new wells drilled after the flood. This method determines water saturations which agree well with water saturations obtained by other methods such as the Electromagnetic Propagation Log, and core analysis. The results agree within a tolerance of 7% of water saturation values obtained from the other methods.
