TGS Announces Two New Ocean Bottom Projects In US Gulf Of Mexico

ASKER, NORWAY -- TGS has announced the first two ocean bottom projects in the shelf region of the U.S. Gulf of Mexico under its collaboration agreement with FairfieldNodal.

The Calypso Full Azimuthal Nodal (FAN) survey is located in the Eugene Island protraction area and will cover 136 shelf blocks. Historical production from Upper and Lower Miocene reservoirs will be complemented by new long offset full azimuth nodal data that will identify new reserve potential in this geologically complex area.

Calypso FAN is being acquired by FairfieldNodal using the Z700 ocean bottom node system, with operations scheduled to restart in November continuing through the full year 2015.

The Nessie FAN survey represents 54 blocks of coverage in the South Timbalier protraction area and will cover a number of existing fields and exploratory acreage. This full azimuth data will provide significant uplift in illumination of existing Miocene reservoirs and emerging inboard Cretaceous and Lower Tertiary opportunities. FairfieldNodal started the Nessie FAN survey in August and will together with TGS complete the survey in Q4 2014. 

"Together, both Calypso FAN and Nessie FAN are expected to provide a new standard of images for exploration and development as the industry experiences a re-emergence of shelf activity in the U.S. Gulf of Mexico," stated Rod Starr, senior VP Western Hemisphere for TGS. Imaging for both data sets will be completed by TGS.

Both projects are supported by industry funding.
