Hydraulic fracturing: Computational modelling
Revue européenne de génie civil, 2006This paper presents an efficient algorithm for modelling hydraulic fracturing based on the finite element method. The algorithm is employed for modelling the different coupled non-linear processes that are involved in the problem of hydraulic fracturing.

Time‐Dependent Hydraulic Fracture Initiation
Journal of Geophysical Research - Solid Earth, 2020Rocks are known to fail in a time‐dependent manner similar to many brittle and quasi‐brittle materials. However, observed time dependence of hydraulic fracture initiation has ubiquitously been attributed to fluid flow‐related mechanisms without ...
