Abstract
In this work, the propagation of a hydraulic fracture in a poroelastic medium containing a circular cavity is considered. Numerical studies are based on the extended finite element method. It is shown that under conditions of hydrostatic compression, the path of crack development depends both on the stress state of the medium, the field around the cavity, and poroelastic effects.
