INTEGRATING VERTICAL SEISMIC PROFILE DATA FOR MICROSEISMIC ANISOTROPY VELOCITY ANALYSIS

摘要

A system and a method for producing an anisotropic velocity model. Vertical seismic profile (VSP) data is obtained for a geological area. At least two stiffness coefficients in a fourth-rank elasticity stiffness tensor are calculated based on p-wave and s-wave velocities determined using the VSP data. Microseismic profile data for the geological area is obtained and all remaining unknown stiffness coefficients in the fourth-rank elasticity stiffness tensor are calculated using the microseismic profile data.
