A hydro‐mechanically‐coupled XFEM model for the injection‐induced evolution of multiple fractures
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 9, Page 1539-1558, 25 June 2023., 2023 Abstract In this paper, a two‐dimensional eXtended Finite Element Method (XFEM) solution is presented for the hydro‐mechanically coupled hydro‐frac‐induced propagation of multiple fractures in rocks. Fractures are considered one‐dimensional objects, and the rock matrix is regarded as a two‐dimensional medium.

Energy Science &Engineering, Volume 11, Issue 2, Page 811-825, February 2023., 2023 To predict the production of fractured horizontal wells more accurately, we establish a numerical simulation model of fractured horizontal wells that considers the threshold pressure gradient, non‐Darcy flow, and stress sensitivity using the embedded discrete fracture model.
