... Abstract Modeling dispersion and attenuation of ultrasonic wave in fluid-saturated rocks at core scale, the effect of the local flow of the pore fluid induced by the passing wave can’t be neglected. The squirt-flow mechanism between pores of different shapes and orientations should...

...), within these formations (Upper Three Forks, and Middle Three Forks), and the microscopic pore distribution effect on hydrocarbon transport for the production using the Nuclear Magnetic Resonance (NMR) approach. The findings indicated that the soaking time improved recovery factors significantly below...

... be quantified. Experimental results show that supercritical CO 2 has a strong replacement capability on crude oil, and at core scale, the replacement occurs in a short time. For Jimsar core samples, the crude oil in the large pores is displaced out firstly, then the smaller pores. At high pressures, the peak...

... into 3 discrete phases (sand grain, bitumen, and pore) and used for digital core construction, then the microstructural deformation is analyzed. At the same time, the variation of porosity, pore radius, and throat radius were quantitatively analyzed by the pore network model. The results show...
