... the pore changes due to CO 2 saturation. Barret Joyner and Halenda (BJH) model was employed to determine the pore structure distribution (pore size, pore volume and surface area) before and after CO 2 saturation. The results show that clay minerals and quartz increased whereas other minerals decreased...

... Abstract Characterizing the pore structure of a shale-gas reservoir is significant for calculating the original gas in place and fluid-flow characteristics. To better understand the impact of organic matter accumulation, redox condition, and depositional environment on pore structure...

... such tight formations by enhancing the wellbore – matrix connectivity, the majority of oil and gas are still trapped in the matrix even after the pressure is depleted in the hydraulic fractures. Therefore, how to characterize pore structure properly in the unconventional reservoirs becomes a critical task...

... Abstract Pore structure is one of the most important parameters affecting the properties of reservoir formations such as storage capacity, mechanical properties, and mass transport potential of hydrocarbon. Quantitative understanding pore structures of the formation have been an essential...

... in this study. The larger value of D represents smaller pore size and more complicated pore structures. The connate water saturation from theoretically derived relative permeability curves for tight cores can reach a value as high as 60–80% and the two-phase flow area is narrow. The total effective permeability...

... measurement of shale pore structure in samples from the Barnett Shale. We exploit the facts that N 2 adsorption is sensitive to pore size distribution (PSD) but not pore topology, while MICP and N 2 desorption are sensitive to both topology and PSD. Our model assumed that the bulk rock is composed...
