Abstract: A method for determining mobile water saturation in a reservoir having a borehole extending through the reservoir is disclosed. The method involves obtaining a first borehole data log while the reservoir is subjected to first fluid conditions, and causing a mobile water displacement in the reservoir by changing the fluid conditions in the borehole to cause the reservoir to be subjected to second fluid conditions, the second fluid conditions differing from the first fluid conditions. The method further involves obtaining a second borehole data log under the second fluid conditions, and estimating the mobile water displacement using the first and second data logs, the estimated mobile water displacement providing an estimate of the mobile water saturation in the reservoir.
