This paper illustrates the use of several independent testing and calculational procedures for determining residual hydrocarbon saturations remaining in a reservoir after waterflooding. These methods consist of material balance calculations, analysis of well test data, pressure transient testing, core analyses, and borehole log calculations. Results of this work indicate (1) good agreement was obtained between the several independent methods; (2) pressure transient testing is a valuable tool for measuring in situ formation properties such as effective permeability to water and total compressibility (values of compressibility obtained indicate gas saturation remaining after waterflooding is essentially zero); (3) water-oil relative permeability data are the important part of the analysis technique laboratory derived data should be carefully examined for validity; (4) field cases show that waterflood performance tends to verify laboratory kDwU/kDoU data as well as indicate residual oil saturation; and (5) careful analysis of borehole logs can be very helpful.
