ARMA 12-389 The integrated use of hydraulic fracture and deformational measurements in permeable rock stress state estimation

摘要

The method of stress state estimation is proposed. This method is based on subsequent measurement of circular contour deformations. The mathematical model is created and numerical modeling of circular contour deformations estimation is carried out. The calculations were made for the case with 2 fractures going from the borehole outline with loading by the cover(sleeve).
