Initially covering Guinea, Guinea-Bissau, Gambia and the AGC zone shared between Guinea-Bissau and Senegal, in July 2011 the survey was extended into Senegalese waters.
In March this year the company announced that a further agreement had been made with the government of Mauritania to continue the survey to cover deepwater acreage off that country. These additional data will increase the total for the NWAAM project to around 26,000 line km, encompassing over 1,600 km of coastline from northern Mauritania to southern Guinea Conakry. It provides the only continuous, conformable, long-offset, well-tie, regional dataset in this underexplored but potentially prospective area.
Dolphin has agreed with Petrosen, Senegal’s National Oil Company, that it will also acquire, process and market a new 3D multi-client survey over deepwater acreage in the Senegalese offshore. These new long-offset data, totalling about 3,600 km2, is due to be completed by mid-May. The survey is designed to image potential submarine turbidite fan plays and will complement the large 2D dataset of the NWAAM 2D Regional Survey.
This major project is a joint venture between Dolphin Geophysical and TGS. Data will be processed in the UK by the latter, and a regional interpretation study is already underway. Road shows are being scheduled in London and Houston later this year when representatives from each of the governments will be present to promote available acreage and hold private discussions with interested companies.
