AVOA technique for fracture characterization: Resolving ambiguity
Main Article Content
Abstract
A new computational technique of AVOA analysis (Amplitude Versus Offset and Azimuth) is developed which resolves an ambiguity in fracture–direction estimation. It analyzes a third term of Rüger's approximation for P–wave reflection coefficient to distinguish symmetry–axis and fracture–strike directions. The technique is tested on synthetic and field data.
