HYDRAULIC FRACTURE SIMULATION WITH AN EXTENDED FINITE ELEMENT METHOD

摘要

A computer-implemented method includes defining respective positions of a first set of nodes and a second set of nodes in an enrichment region, and performing a coupled pore fluid diffusion and stress analysis on the enrichment region at the first set of nodes. It is then determined whether the second set of nodes is activated—representing a fracture—as a result of the analysis, and the results are visually output to a user.
