3-D AVO migration/inversion of field data

Abstract

This article describes the methodology for AVO migration/inversion and presents the results of its first field application. 3-D AVO migration/inversion can be applied in areas with lateral velocity variations and dipping events in which conventional AVO analysis is not valid. The method has been tested on both synthetic and field data in 1-D, 2-D, and 3-D cases and its accuracy verified.
