Offshore staff

ASKER, NorwayTGS has announced the first two ocean bottom projects in the shelf region of the US Gulf of Mexico under its collaboration agreement with FairfieldNodal.

The Calypso Full Azimuthal Nodal (FAN) survey is 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 aims to 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 and continuing through 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 should 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 4Q 2014.
