ASKER, NorwayTGS, PGS, and GeoPartners have completed the Jaan 3D seismic survey over the MSGBC basin offshore northwest Africa.

The survey covered an area of more than 28,000 sq km (10,811 sq mi) off Senegal, The Gambia, AGC and Guinea-Bissau.

It was designed to map the Cretaceous Palaeo Shelf-Edge Trend and to shed light on the untapped Jurassic potential, the setting that delivered the deepwater FAN and SNE oil discoveries off Senegal.

Jaan 3D comprises more than 12,000 sq km (4,633 sq mi) of new data, plus recently reprocessed seismic surveys. According to TGS, the 3D PSTM and PSDM volumes give a wider picture of the basin and its unique geological features of the shelf edge trend across borders.

It is also the setting for various ongoing and anticipated bid rounds, including Senegal’s 2020 License Round, which includes acreage on-trend with FAN and SNE.

Offshore The Gambia, Jaan 3D covers an area of prospectivity said to be similar to the FAR/Petronas targets in adjacent blocks.
