... Abstract To study in-situ rock stress measurement under different fracture medium, the hydraulic fracturing experiments in lab were carried out using true three axis hydraulic pressure fracture simulating system. The granite specimens with their sizes of 400mmx400mmx400mm were used. In order...

... ABSTRACT: Hydraulic fracturing had been a widely applied method of measuring stresses in a drilled borehole. During the test procedure, induced forces due to the interaction between fluid flow and rock blocks deformation overcome the in-situ least stress. Thus the coupled hydromechanical...
