Evaluation method of the least horizontal principal stress by logging data in anisotropic fast formations
Abstract: For transverse isotropic fast formations, the evaluation method of the least horizontal principal stress by using logging data is an important unresolved issue.An innovative method is proposed to solve this problem by derivation of five independent stiffness coefficients (C11, C33, C44, C66 and C13) in this kind of formation.Based lamzu t
