... revealed precipitation of barium sulfate and carbonate (barite/witherite). Despite the precipitation, the permeability of the fracture system changed little following the initial fracturing event. Precipitation was likely confined to relatively stagnant flow regions, with more open regions sustaining high...

... ABSTRACT: Reservoir permeability is a critical parameter for the evaluation of hydrocarbon reservoirs. It is often measured in the laboratory from reservoir core samples or evaluated from well test data. The prediction of reservoir rock permeability utilizing well log and seismic data...

... test of different proppants. The experimental results show that the conductivity of gas measurement is much greater than that of liquid measurement, and the former is about 12.6 times that of the latter. Related to the air permeability and water-resistance of the experimental film coating material...

The fracture length and width build with the increase of perforation density, diameter, and decrease with permeability and minimum horizontal principal stress. Moreover, the effect of limiting entry fracturing...

... permeability, compressive strength, Young’s modulus and stress-strain characteristics, were evaluated before and after high-temperature treatments. The results show that silica-modified cement can maintain reasonably high compressive strength and Young’s modulus after exposure to 550 C for 7 days. The use...
