Offshore staff

ASKER, Norway – PGS and joint venture partner TGS have completed the fifth consecutive seismic acquisition season offshore Newfoundland and Labrador.

There were many “firsts” associated with this year’s seismic season:

  • First multi-client 3D seismic survey to be acquired on open acreage under the Scheduled Land Tenure System
  • First multi-client 3D seismic to fulfill a work program obligation offshore Newfoundland and Labrador
  • Most 3D seismic ever acquired in a single season offshore Newfoundland and Labrador.

The Ramform Valiant acquired 4,339 sq km (1,675 sq mi) over exploration block EL-1135 in the Flemish Pass basin. The survey was acquired with a towing spread of 10 x 8 100 m streamer lengths with 100 m streamer separation. The data is currently being processed by PGS in its Houston office. Completion is expected in 2Q 2016.

Farther north in the Orphan basin, the Ramform Viking acquired 4,555 sq km (1,759 sq mi) of 3D seismic with a very similar towing configuration over a high graded area in Sector NL02-EN, which will be the subject of the Call for Bids in November 2016. This survey was supported by Nalcor Energy.

Pre-processing of the initial GeoStreamer signal was carried out by PGS onboard the vessel following which TGS will perform data processing in its Houston office. A fasttrack pre stack time migrated volume will be available for license before the end of the year with final processing scheduled to be completed in 2Q 2016.

The Atlantic Explorer and Sanco Spirit acquired more than 27,000 line km (16,777 mi) of 2D GeoStreamer data in the Labrador Sea, Orphan basin, and Southern Grand Banks. The joint venture’s multi-client 2D library in the area now consists of more than 110,000 line km (68,350 mi) of GeoStreamer data.
