Harbour Energy PLC flow tested the Timpan-1 exploration well on the Andaman II license, 150 km offshore North Sumatra, Indonesia, in 4,245 ft of water. While the well has encountered a material gas accumulation, further work will be required to establish commerciality and the full potential of the play across the license.
The well was drilled to a total vertical depth of 13,818 ft subsea and encountered a 390-ft gas column in a high net-to-gross, fine-grained sandstone reservoir with associated permeability of 1-10 millidarcies. A full data acquisition program has been completed including wireline logging, 240 ft of core recovered, and a drill stem test. The well flowed on test at 27 MMscfd gas and 1,884 b/d of associated 58° API condensate through a 56/64-in. choke.
Premier Oil Andaman Ltd., a Harbour Energy Co., is operator of the license (40%) with partners bp PLC (30%) and Mubadala Petroleum PLC (30%).
