It is a standard industry practice to compute water saturation from resistivity logs. Spuriously high water saturation has often been computed in hydrocarbon bearing reservoirs with low formation resistivity, resulting in underestimation of hydrocarbon resources. One common approach to overcome this problem is to use capillary pressure data from cores. Although technically sound, its main drawback is that most wells lack appropriate core data.

This presentation proposes that generic capillary pressure curves generated using core data from typical sandstone reservoirs can be used to compute water saturation in other similar sandstone reservoirs from different areas or regions. This is based on the assumption that sandstone reservoirs having similar Reservoir Quality Index and wettability, will exhibit similar capillary pressure behavior with respect to the wetting phase saturation, namely water saturation. Generic capillary pressure curves have been generated using actual core data from several wells in Malaysia. Empirical relationships were established between curve fitting parameters and the RQI values of the core plugs. The generic capillary pressure curves were then used to compute water saturation in other wells, which do not have core data. The pseudo RQI values for these wells were generated using the log derived porosity and permeability. With these pseudo RQI values and height above the Free Water Level, a water saturation equation was generated, as a function of RQI and height.

The results have been verified in test wells, which have their own core data. In wells without core data, water saturation derived from generic capillary curves was compared with that computed from resistivity logs. These water saturation values were found to be more realistic than those computed from resistivity logs alone. Well test results, where available, also confirmed the validity of the method used and the reliability of the computed water saturation. The results from these experiments confirmed the assumption that generic capillary curves can be used to predict water saturation in wells without core data. A Saturation Height Function has also been generated using the generic capillary pressure data. This saturation height function has been tested and used in several geocellular models for Full Field Reviews, with good results. It has been adopted for computing water saturation independent of resistivity logs.
