HOUSTON, Oct. 26 -- A gas discovery in the North Sumatra basin waters of the Malacca Straits is described as noncommercial but encouraging for further exploration.
Serica Energy PLC, Toronto, did not test the Togar-1A exploration well on the 2,185-sq-km Asahan PSC but said it found gas that analyzed 96% methane in Miocene Middle Keutapang sandstones topped at 3,385 ft subsea.
The well cut 22 ft of net gas pay and found a gas-water contact at 3,410 ft subsea. Porosities reached 35%. Of several other Middle Keutapang reservoirs encountered, only one held gas at the Togar-1A location. TD is 6,451 ft subsea.
Serica Energy, with 55% interest, released the Galaxy Driller semisubmersible, advertised for a rig for 2006 drilling, and is looking for other drilling locations on the block. Its partners are Duinord Asahan Petroleum Inc., Jagen Asahan Pty. Ltd.,
PT Risjad Salim Resources Asahan, and Greevest Asahan Pty. Ltd.
