REMOVAL OF FRACTURE-INDUCED ANISOTROPY FROM CONVERTED-WAVE SEISMIC AMPLITUDES

摘要

The present disclosure provides a system and method for inferring one or more physical property parameters of a sub-surface media by inverting converted wave data acquired during a seismic survey. Composite seismic traces are generated at a plurality of survey azimuths (step 609). These composite traces are composed such that their amplitudes are free of effects of subsurface anisotropy. At least one of the generated composite seismic traces is then inverted by isotropic inversion to determine a property parameter of the subsurface media (step 623).
