GAMBIA: TGS holds large quantity of modern subsurface data
By Eyo Nsima
TGS, a leading Energy Data Company, has disclosed that it holds a large quantity of modern subsurface data offshore The Gambia, including 2D and 3D seismic.
The company provides energy data and intelligence to companies and investors across energy markets while offering the world’s largest global energy data library, including seismic data, magnetic and gravity data, multi-beam and coring, digital well log and production data, wind energy data, data to identify CCS opportunities, and other types of renewable data.
In its latest brief obtained by The Daily, www.thedaily-ng.com, PGS, stated: “Broadband reprocessed 3D data clearly defines the basin floor fan slope play (as seen in the FAN-1 discovery) and shelf edge (SNE discoveries) and cenomanian sand buried hill (Belatrix-1 discovery) with data quality that allows geophysical de-risking of identified leads and prospects to the highest standard, such as Eland and Oribi – previously developed by British Petroleum, BP across Blocks A1/A4, estimating in-place resources in cumulation of 1,000 million barrels and beyond.
“These data sets are continuous across the wider region, giving potential explorers a wealth of valuable information on the potential prospectivity of the area, including ties to SNE-2-SNE-6, BEL-1 and VR-1, the ‘Sangomar development’ 2C contingent oil resource stands at 563 mmbbls.
“The North West African Atlantic margin (NWAAM) is still one of the hottest exploration areas in Africa; despite the fact exploration has been ongoing since the 1960s. In 2014 the discovery made in Senegal by FAN-1 threw an enormous spotlight on the region, at the time reported as 950 mmbbls of oil, in an Albian reservoir slop floor fan. As ‘fields that keep on giving’ next door to The Gambia, FAN South-1 re-established the area’s potential to grow, by proving that the petroleum system is working for commercial oil.
“Continuous sedimentation of Albian-Turonian shales occurred in this sub-basin, probably due to two major rivers; the Gambia and Saloum. New technologies such as multi-beam and seafloor sampling are now covering offshore Senegal, The Gambia and Guinea-Bissau, further de-risking hydrocarbon presence, especially for the fact of having both phases, gas and oil, present.”
