TGS-Nopec begins 2D seismic survey offshore Louisiana

TGS-Nopec Geophysical Co. has begun Phase 50, a 2D multi-client seismic program in the offshore Louisiana area of central Gulf of Mexico. The Phase 50 program is designed to improve the image of the deeper geology to fully explore the deep gas play on the Louisiana shelf.

TGS-Nopec Geophysical Co. has begun Phase 50, a 2D multi-client seismic program in the offshore Louisiana area of central Gulf of Mexico.
The Phase 50 program is designed to improve the image of the deeper geology to fully explore the deep gas play on the Louisiana shelf. Earlier in 2002, TGS-Nopec acquired a 3,400-km proof of concept pilot program with super long acquisition offsets and Kirchhoff prestack time migration processing.
The results of the pilot project demonstrate improvements in image quality of the deeper data, generating enough interest and funding from exploration companies to expand the program to 48,000 km.
Acquisition of the expanded Phase 50 program began in early October with the M/V Odin Explorer. TGS-Nopec plans to add the M/V Zephyr to the project in November 2002. The 8,000-m streamer lengths and 14-second record lengths incorporated into Phase 50 exceed previous acquisition technology on any 2D projects in the area.
