TGS is starting a new seismic survey in the MSGBC Basin, offshore north-west Africa. The Senegal North Ultra-Deep Offshore (SN-UDO-19) 3D survey covers more than 5100 km2. The project is being undertaken in partnership with GeoPartners using the vessel, BGP Prospector and has the full support of the Senegalese national oil company, Petrosen.
This stand-alone survey is located in northern Senegal and is a continuation of the recently completed SS-UDO-19 3D acquisition in southern Senegal. The survey has been designed to illuminate plays in ultra-deep water, enabling explorers to build on the success the basin has experienced with the Sangomar field, the GTA complex and Yakaar discoveries. The project has a 75-day acquisition timeline, with fast-track data available three months after acquisition, in time for evaluation of blocks available in the recently announced Senegal Offshore 2020 Licensing Round. The full dataset will be available by Q4 2020.
Kristian Johansen, CEO of TGS, said: ‘This survey will provide the industry with essential subsurface insight ahead of Senegal’s Offshore Licensing Round which is scheduled to commence early next year. SN-UDO-19 extends our coverage in a highly prospective region where TGS has been actively acquiring data for almost two years.’
Meanwhile, TGS has added a further 1500 km2 of 3D seismic data offshore The Gambia. This dataset will further expand TGS’ existing 3D multi-client library in the MSGBC Basin, which now totals more than 40,000 km2.
The survey falls over Blocks A2/ A5 where sub-surface structures have been identified as being on-trend with the SNE discovery immediately north in Senegal. The dataset will be reprocessed and pre-stack merged into the Jaan programme, a 29,000 km2 3D covering the prospective paleo-shelf edge.
Graham Mayhew, VP Africa, Mediterranean and Middle East at TGS, said: ‘We expect to see further discoveries made in this basin and believe our 3D data will be critical in providing exploration companies the ability to invest further.’
