Abstract

Fluid pressure inside a borehole produces hydraulic fracture and damage zones in the vicinity of the borehole. These fractures result from stress concentrations around the borehole. The results of numerical simulation of a borehole subjected to fluid pressure using a micromechanical damage model [2] are presented in this paper. It is observed that tensional concentrated stresses are generated around the bottom of the borehole by the applied fluid pressure. Furthermore, fractures develop from the corners of the bottom of the borehole.
