... propagation. The stress and pressure field changes were found to explain such an asymmetry. Stephenson et al. (2018) revealed that the fracture propagation of a well in a complex in-situ stress field could be asymmetric. Guo et al. (2019) found from numerical studies of the Eagle Ford shale that an injection...
