Cap Energy has informed that it is working to progress its interests offshore Guinea-Bissau, West Africa, by conducting a 3D survey scheduled for November, 2014.
Sitting in the same basin as the Company’s Senegal assets, the prospective leads are distributed across a carbonate shelf that passes abruptly to deeper water to the west.
As the deepwater geology of Cap’s Block 5B is analogous to that of the FAN-1 location in Senegal, Cap plans to use the results of Cairn’s well to look for similar prospects in its Guinea-Bissau acreage.
The company says this will become more accurate when tied into a 3D survey planned to start in November 2014 over Block 5B. Cap Energy says that the presence of source rock in FAN-1 increases confidence that it is also present in Guinea-Bissau. In addition, seismic survey operator Polarcus has carried out two 3D surveys offshore Guinea- Bissau separate to Cap’s blocks, which have identified several fan systems on the shelf edge similar to those in Senegal.
Preparations are being finalised for the Block 5B survey to de-risk the leads identified on 2D seismic. The majority of leads here sit on the shelf, in water depths between 1,125m and 3,150m, although some sit in water depths of 3,200m to 3,500m. The P50 STOIIPs are mostly over 100mmbbls, with the largest assessed at 2,433mmbbl.
Block 1 sits in much shallower waters of up to 100m and within easy reach of shore. The mean prospective resources are in the region of 50-120mmbbls. A Virtual Drilling analysis on Block 1 seismic data is underway to identify prospects and is expected to be completed by the end of 2014.
