ADELAIDE, Australia -- The Dua-5X well has recorded multiple gas and oil reservoirs in the southern fault block of the Dua structure in block 12 E, offshore Vietnam.
Two reservoir intervals have been tested with the primary reservoir target flowing oil at 5,543 b/d of oil plus 6.76 MMscf/d gas through a 2-inch choke, said block partner Santos Ltd.
A deeper secondary reservoir flowed at 247 b/d of oil through a 28/64" choke, it said, adding that neither zone produced water on test.
Santos and partners would commence work on the resource assessment and preparation of a reservoir evaluation report, the first step in the commercialization process within the Production Sharing Contract (PSC) terms.
Santos and partner Premier Oil had drilled Dua-4X and Dua-4X ST1 wells in the northern fault block of the Dua structure. These wells were step-outs from the 1974-drilled Dua-1X discovery well, which then flowed at 1,500 b/d from the main reservoir.
Wireline testing of both Dua-4X and Dua-4X ST1 recovered oil samples and pressure data.
Following completion of operations on Dua-5X, the rig is scheduled to drill well 12E-CS-1X on the Blackbird prospect, also in block 12E, exploring a large tilted fault block up-dip of a previous well that encountered very good oil shows, said Santos.
Interests in Block 12E are: Santos International Holdings Pty Ltd 37.5% in Block 12E with operator Premier Oil plc 37.5% and Delek Energy 25%.
