Simulation of Fracture Morphology during Sequential Fracturing

Processes, 2022
During hydraulic fracturing, the aperture of hydraulic fractures will shrink by the in-situ stress, but will not fully close because of the existence of proppant inside the fracture. In previous studies, few people noticed the existence of proppant, which has resulted in the inaccuracy of simulation results. In this study, based on the boundary element

Characteristics Analysis of Three-Component Wave Field Based on Borehole Microseismic Data of Shear Wave Splitting

Cejing jishu, 2023
The wave field data which is monitored the fracturing crack by micro seismic in the well is complex, especially when the shear wave (S-wave) encounters the fracture. The shear wave will split into the fast or slow wave. The polarization directions of the
