... a stress field characterization, the reservoir conditions are reproduced. Then, the drilling process, casing and cement shield integrity, hydraulic fracturing and production are simulated. The model initialization reproduces the undisturbed condition of the rock mass. After this point, the drilling process...

.... Local stress fields around the fractures will change during reservoir depletion due to the fluid flow and deformation induced by fractures mechanical interference. The stress rotation is controlled by the magnitude of anisotropic stress, which is dependent on several reservoir and material properties...
