Imaging through Gas Clouds - a Case History from the Gulf of Mexico

A-09 IMAGING THROUGH GAS CLOUDS - A CASE HISTORY FROM THE GULF OF MEXICO Summary 1 Results from the worlds largest 3D four component OBC seismic survey will be presented. Located in the West Cameron area offshore Gulf of Mexico the survey operation totaled over 1000 square kilometers and covered more than 46 OCS blocks. The area contains numerous gas invaded zones and shallow gas anomalies that disturb the image on conventional 3D seismic which only records compressional data. Converted shear wave data allows images to be obtained that are unobstructed by the gas and/or fluids. This reduces the risk
