Senegal Brokered 3D

Senegal Brokered 3D Surveys

London (12th June 2023) GeoPartners are pleased to announce the availability of exclusive 3D seismic data sets offshore Senegal. In partnership with Petrosen E&P we are able to make available for multi-client licensing over 11,000 sq.km of high-quality 3D seismic data. The 3D surveys can also be tied into the larger regional scene via the NWAAM2012 and 2017 2D seismic surveys in the MSGBC Basin.

Senegal is soon to become an oil producing nation later this year when Woodside brings onstream the Sangomar field which should lift 100,000 bbls of oil per day to the surface. The SNE-1 well which discovered Sangomar was the second well drilled in Senegal in 2014, after the FAN-1 well discovered oil in a Lower Cretaceous base of slope turbidite fan, the largest global discovery that year (before SNE-1 replaced it). 

The FAN-1 well found no oil-water contact in a gross oil bearing interval of more than 500m, with oil types, indicated from a number of oil samples, ranging from 28° API up to 41° API . The gross STOIIP estimates for the FAN-1 well range from 250 mmbbls (P90), 950 mmbbls (P50) to 2,500 mmbbls (P10). FAN-1 was followed up with the FAN South-1 well in 2017, which again encountered a Lower Cretaceous hydrocarbon bearing reservoir with 31° API oil recovered. These are the only two penetrations of the oil-charged turbidite reservoirs in the Sangomar Deep block, which is now open following Woodside’s relinquishment in 2022 to focus on the Sangomar FPSO construction.
