Experimental study This section presents the experimental setup and equipment used to perform an SSTT, rock and fluid properties, a description of the experimental protocol...

... for shale water spontaneous imbibition under the conditions of formation temperature and confining pressure was designed. Finally, the wettability index was proposed to quantitatively evaluate the water wettability, oil wettability and mixed wettability of shale. The experimental results shown...

... Abstract A clear description of the wettability of carbonate rocks poses numerous challenges due to its non-uniformity and uncertainty caused by complex pore systems and weak fluid/rock interactions. Aging in the crude oil and spontaneous brine imbibition of core samples in the laboratory...

... are featuring large capillary pressure thus spontaneous imbibition. Surfactant would accelerate this process. However, due to the small amount of oil in core, the accurate recording of oil recovery is challenging, especially during dynamic imbibition within fracture matrix system. Nuclear Magnetic Resonance...

... Abstract To understand the interactions between shale rocks and aqueous drilling fluids, the spontaneous imbibition of water phase into shale pore systemsneeds to be investigated. It is important to study the shale-fluid interactions to mitigate problems associated with drilling shale...

... us to explain these lateral variations across the field. Observations infer that a tilting episode has sunk the NW part of the structure, post oil migration. Consequently, the oil-filled rock that submerged below Free Water Level (FWL) underwent imbibition. The evidence of imbibition is now seen...

... in carbonate reservoirs that present preferably oil-wet or mixed wet. In this case, the wettability alteration should be triggered by a kind of surfactants that can change the wettability towards water-wet and induce the spontaneous imbibition of injection fluid into the carbonate matrix for higher oil...

... aims at identifying and analyzing the influence of high-frequency, high-intensity ultrasonic radiation on capillary imbibition. Laboratory experiments were performed using cylindrical Berea sandstone and Indiana limestone samples with all sides (co-current imbibition) and only one side (counter-current...

... Abstract Spontaneous water imbibition is an important recovery mechanism in water-flooding particularly in naturally fractured reservoirs. Scaling the core test data of spontaneous capillary imbibition with different injection fluids is crucial to properly design improved recovery methods...

... Abstract An approach was developed to extract the imbibition capillary pressure and the global mobility data from spontaneous water imbibition tests in oil-water-rock systems. Capillary pressure and global mobility data were calculated using this method with the experimental data...

... and shut during the (field) lifetime of a reservoir, both imbibition and drainage may occur in different parts of a reservoir. The numerical model will take into account the irreversibility of imbibition and drainage, commonly known as hysteresis, which applies for both capillary pressure and relative...
