Imbibition Test, Wettability, Weighing MethodAbstract
The propensity of one fluid in a fluid pair to coat the surface voluntarily is known as wettability. Fluid distribution and flow behavior in porous rocks mainly controlled by wettability. Oil recovery by water flooding depend mainly on the wettability of the reservoir rock. Many methods used for wettability measurement. These methods are qualitative and quantitative. Spontaneous imbibition is one of widely used methods for quantitative wettability measurement. Direct measurement and weighing technique are two known methods for spontaneous imbibition measurement. This work presents comparison between the two aforementioned methods. Experimental measurement of spontaneous imbibition achieved on core samples from the same source. Results approved that the samples are water wet but having different tendencies, the imbibition rate related to time have variable trend in addition, ultimate water saturation in weighing method experiment are higher than that in volume measurement method. The weighing method is better than the volume measurement method.
