Integrating vertical seismic profile data for microseismic anisotropy velocity analysis

A system for producing an anisotropic velocity model, the system comprising a processor;

• and a computer readable medium having stored thereon a plurality of instructions for causing the processor to perform a method comprising:
• calculating, via a processor, p-wave and s-wave velocities along a vertically symmetrical axis using vertical seismic profile (VSP) data for a geological area;
• calculating, via a processor, at least two stiffness coefficients in a fourth-rank elasticity stiffness tensor using the p-wave and s-wave velocities;
• calculating, via a processor, all remaining unknown stiffness coefficients in the fourth-rank elasticity stiffness tensor using microseismic profile data for the geological area.
