TGS Extends Eastern Delta Gulf of Mexico Multi-Client 3D Survey

TGS-NOPEC Geophysical Company has reached an agreement to extend its multi-client 3D seismic survey in the Main Pass and Viosca Knoll areas of the Gulf of Mexico. Motivated by client pre-funding in the area, the survey will increase from 1800 square kilometers to 2400 square kilometers.

TGS contracted Reservoir Exploration Technology AS (RXT) to perform the acquisition of the survey utilizing a Vector-Seis Ocean Bottom Cable recording system. The Eastern Delta survey commenced in February of this year and the initial results of the newly acquired data have shown significantly improved data resolution over the existing data in the area. TGS Imaging is processing the data utilizing its proprietary PRIMA(TM) technology and will produce pre-stack time and pre-stack depth migration data volumes.

The Main Pass/Viosca Knoll area is a very mature hydrocarbon producing region and the TGS Eastern Delta program is the first modern vintage, long offset (9000+ meter) 3D data recorded in the area. Water depths in the survey area range from 10 to 400 meters.

The Eastern Delta program is supported by pre-funding from multiple independent and major oil companies. Survey acquisition is now expected to be complete in January of 2007.
