SNE and FAN World Class Discoveries Offshore Senegal Herald a Major New Hydrocarbon Province

Historically, interest in MSGBC (Mauritania-Senegal-Gambia-Bissau-Conakry) had been limited and Senegal had been largely overlooked.

In early 2006, FAR Limited acquired an interest from then operator Hunt Oil in the Rufisque Offshore, Sangomar Offshore and Sangomar Deep Offshore blocks in Senegal. A large 2000km2 3D seismic survey was acquired but Hunt Oil exited the area shortly thereafter, leaving FAR as operator with 90% equity along with Petrosen, the national oil company of Senegal (10%).

In 2012, a detailed mapping and prospect generation exercise was carried out by FAR, resulting in an updated prospect and lead portfolio, which was taken to the farm-out market. Farm-out deals were concluded with Cairn Energy (operator; 40%), ConocoPhillips (35%), FAR retaining 15% and Petrosen 10%.

Two initial exploratory wells were drilled, back to back, on two separate plays in 2014. FAN-1, the first ever deepwater well in Senegal was drilled in 1,427m water depth, targeting stacked Cretaceous sandstone reservoirs in stratigraphic traps. The well was drilled to a total depth of 4927m with excellent oil indications over a vertical interval of over 500m and no oil-water contacts encountered. Several distinct oil types were sampled ranging from 28° API to 41° API. The main reservoir sections are thinly bedded, yielding approximately 29m of net oil pay in Albian sandstones. The FAN-1 discovery is larger than the pre-drill estimate and audited 2C recoverable resources are 198mmbbls. In addition to discovering oil, FAN-1 encountered a thick interval of excellent quality oil-prone source rocks.

SNE-1 in 1,100m water depth, was drilled to a total depth of ~3,000m. The well targeted Cretaceous sandstone reservoirs in a combined structural and stratigraphic trap. Oil and gas were encountered at the primary objective in excellent quality Albian sandstones with a gross 96m oil column and net oil pay of 36m. High quality 32° API oil was sampled, together with gas and water.  Early appraisal results confirmed the continuity of the main oil and gas columns and a DST of the first appraisal well (SNE-2) flowed oil at a constrained rate of 8000mmbbls per day. Audited 2C recoverable resources are 641mmbbls. These figures are about four-fold larger than the pre-drill estimate.  

A second FAN type feature was successfully drilled by FAN South-1. As such, a total of eleven wells have been drilled on the blocks, all of which encountered hydrocarbons. First oil from SNE is expected between 2021 and 2023.

The story is evolving but these exceptional exploration results have confirmed the Senegal offshore as a new major oil province.
