Medco Energi finds more gas in South Sumatra

PT Medco Energi Internasional has discovered additional oil and gas at the Hijau-2 well in South Sumatera Block, Indonesia and from the O2 well in Area 47, Libya.

The Hijau-2 delineation well, located in the South Sumatra PSC, was drilled to a vertical depth of 5,695 ft. (1,736 meters), proving a 35-meter gas column in the Baturaja limestone formation. A drill stem test confirmed a gas flowrate of 5.05 million standard cubic feet per day through a 24/64 inch choke. MedcoEnergi describes the well as a “prospect opener” in the still prolific South Sumatra basin, where the company has substantial acreage. This discovery is assessed as commercially viable, South Sumatra being an area with existing infrastructure and high gas demand. It will increase the company’s gas production for the domestic market.

O2 well was spudded on 23 May 2014 and drilled to a total depth of 10,780 feet. Initial tests demonstrated the well flowing 3,300 barrels of oil per day and 140,000 standard cubic feet per day of gas through a 48/64 inch choke in the Top Lower Akakus formation. The O2 well location that lie outside reservoir closing contour proved the existence of stratigraphic element that may have connection to multiple structures in the area. The discovery of O2 well and P2 well in last July 2014 again proved the prolific hydrocarbon area of Ghadames Basin in Area 47, where large oil and gas reserves was discovered with a 90% exploration success rate (18 out 20 exploration wells discovered oil and gas).

Furthermore, on 17 September 2014 the Government of Libya declared the commerciality of B, C and J structures in Area 47. MedcoEnergi, with its partners National Oil Corporation (NOC) Libya and Libyan Investment Authority (LIA), will commence this development together with the A, D and F structures, previously declared commercial in 2011. Combined, the total estimated oil and gas recoverable reserves is 250 MMBOE.
