Method for determining the presence of hydrocarbons in subsurface geological formations by comparative assessment of compressional and shear wave reflection data

摘要

Method for determining the presence of hydrocarbons in subsurface geological formations by comparative assessment of compressional wave reflection information and shear wave reflection information estimated from acquired compressional wave information from common depth point gathered compressional wave traces using variations in the amplitude of the gathered compressional waves with source-receiver offset.
