The second test of an additional 12-m zone resulted in a maximum flow rate of 5,300 b/d through a 1-in. choke followed by a 24-hr flow period at an average flow rate of 4,600 b/d through a 52/64-in. choke.
Perth-based FAR Ltd., a member of the combine, says the SNE-5 and SNE-6 wells are sufficiently connected to optimize production of the S480 reservoirs with water flood-enhanced recovery techniques.
FAR said further analysis will take place once interference test data have been collected from all the observation wells, including SNE-3 and SNE-4, to determine the impact on modelled reservoir architecture, recoverable resource base, and forward development plan.
There is now sufficient data to get on with predevelopment work. The combine plans to submit a field development plan to the Senegal government next year.
The Stena Drilling Ltd. Stena DrillMAX rig is now moving to a pure exploration well: FAN South-1 in 2,139 m of water. The prospect lies to the southwest of SNE field and has two main objectives.
The first is an Upper Cretaceous-age stacked, multilayer, channelled turbidite fan. The second is the Lower Cretaceous base of the slope turbidite fan, which is equivalent to the FAN-1 oil discovery to the north made in 2014.
