Abstract
Natural micro-fractures are very important in the control of production in the hydrocarbon reservoirs. The presence of the vertical fractures in the rock mass causes the split of the incident shear wave into two approximately orthogonal components with different velocities. Shear wave splitting analysis permits the estimation of fracture orientation.
