METHOD FOR DETERMINING RESIDUAL OIL SATURATION OF A WATERED-OUT RESERVOIR Abstract of the Disclosure A method for determining residual oil saturation of a watered-out reservoir using two water soluble tracers having different partition coefficients in oil. The partitioning tracers are selected from the group consisting of tritiated or carbon 14 tagged alcohols, ketones, aldehydes, water and oil insoluble inorganics and organic radioactive isotopes. The tracers are injected into the formation, and their production curves are analyzed over a period of time to determine chromatographic separation of the tracers. |
