Savannah Petroleum PLC, London, is firming its license in southeastern Niger after making an indicated oil discovery in the R3 part of its R3/R4 production sharing contract area (OGJ Online, July 27, 2016).
It received a 1-year extension of its PSC for the R1/R2 area, which is adjacent to R3/R4 to the northwest. The first phase of Savannah’s exclusive exploration authorization now will expire on Aug. 5, 2019.
On R3, the Bushiya-1 exploration well last month logged 10 m of net oil-bearing sandstone across two intervals in the primary Eocene Sokor Alternances objective. Wireline logs indicated excellent reservoir quality in both intervals, which pressure data indicated hold light oil.
Savannah brought an oil sample to surface from the shallower section but could not sample the lower interval because of equipment limitations.
The well, which went to 2,200 m, is being suspended for testing after drilling of two more exploration wells.
Like Bushiya-1, the next well, Amdigh-1, will test the Sokor Alternances as the primary target and the Eocene-Oligocene Upper Sokor as a secondary objective.
Savannah’s PSC areas are in the Agadem Rift basin near oil-producing fields discovered by China National Petroleum Corp., including Goumeri and Sokor.
