B-18 HOW CAN LOG AND CORE VELOCITY ANISOTROPY MEASUREMENTS IMPROVE SEISMIC PROCESSING Summary 1 An elastic Transversely Isotropic with Vertical symmetry axis (TIV) material can be conveniently described by the Thomsen’s theory. Using horizontal and vertical well data drilled in deep offshore deposits a strong anisotropy has been observed in the shaly formations for P and S velocities. These results have been confirmed by core measurements made on vertical and horizontal shaly plugs. e ranges with depth from 10% to 30% γ reaches 35%. A walkabove has been acquired and processed over the sub-horizontal well. It gives the same range |
