... is devoid of any microcracks. The results show that, for shale cores with microcracks, both pyrite oxidation/dissolution and barite precipitation can extend millimeters into the matrix, depending on mineral compositions of the shale. Following 3 weeks of reaction, the carbonate-poor Marcellus system had...

... fluid reaction. The occurrence of barite precipitation in the Marcellus sample and accumulation inside the limited microcracks, resulted in occlusion of the main transport flow paths and a reduction in permeability. As for the Eagle Ford sample, even though barite precipitation also occurs...

... of a stimulated well and, ultimately, to quantify reservoir recovery factors. We seek to understand and quantify how such relationships depend on fracture and microcrack patterns adjacent to matrix pores and understand the reasons why they can vary significantly from traditional correlations, such as the Washburn...

... cracks in each segment are measured. The drainage distance from the main fracture and the development of the microcracks are being investigated. The possibility of a cyclic distribution behavior was clear around the main fracture. The results will help understanding and quantifying the amount of damage...

.... A dual porosity model is constructed to examine gas transport through a system of micropores and microcracks. In this sense, the role of the two different size pore systems is deconvolved. In some cases, the micropore system carries roughly a third of the gas flow. The porosity, permeability...
