Why NOAKA OBN?

The NOAKA Ocean Bottom Node (OBN) surveys lie between Oseberg and Alvheim in the Norwegian North Sea, in an area containing both held and open acreage. They cover over 434 square kilometers (total area under receiver) of the Norwegian Continental Shelf (NCS), an area that has recently witnessed significant Infrastructure-Led Exploration (ILX) activity.

Split into two acquisition projects, the processing of the NOAKA21 survey was completed in Q4 2022, and the more recently acquired NOAKA22 data was readily available in Q4 2023.

TGS-Data-Library-2

This region has seen significant exploration success in recent years, including the development of the NOAKA fields, one of the largest developments on the NCS, with recoverable reserves of more than 500 million barrels of oil equivalents. The new data will stimulate near-field exploration and infill drilling.​

​These surveys cement TGS' leading position in delivering multi-client OBN data. We continue to support E&P companies in their efforts to maximize the lifespan of current production activities and discover additional hydrocarbon reserves offshore Norway. OBN remains the key to realizing these objectives.
