Abstract
A method for determining the fluid saturation conditions of a porous material containing a liquid hydrocarbon. An insoluble displacing liquid is pumped into such porous material and displaces the liquid hydrocarbon. The amount of displaced liquid hydrocarbon is monitored as a measure of the saturation condition of the porous material at any given time.
Claims5
A method for determining the characteristics of a porous material from a subterranean formation, comprising:
- (a) establishing a closed fluid system of a multiphase fluid, one phase being a liquid hydrocarbon and another phase being an insoluble displacing liquid, said hydrocarbon phase and said displacing liquid phase separating and forming a fluid interface between said phases,
- (b) placing a sample of said porous material into said closed fluid system,
- (c) detecting the level of said fluid interface under static conditions,
- (d) pumping a portion of said hydrocarbon phase into a first end of said sample,
- (e) pumping a portion of said displacing liquid phase into said first end of said sample, whereby said sample is saturated with said hydrocarbon phase and said displacing liquid phase and
- (f) detecting a change in the level of said fluid interface in response to the flow of the hydrocarbon phase and displacing liquid phase through said sample, said fluid change being representative of the saturation characteristics of said porous material.
