DST-2, over the interval 1,927 – 1,931m flowed 320 barrels of oil per day, 6,093 barrels of water per day and gas in amounts too low to measure.

DST-3, a co-mingled test over the intervals 1,927 – 1,931mm and 1,933 – 1,935m flowed 379 barrels of oil per day, 7,022 barrels of water per day and 0.102 mmscf/d gas.

The high water production from the test intervals does not correspond with the evaluation of electric logs and pressure data obtained across the Qishn S2 Sandstone interval in Nabrajah-2. Oil Search believes the high water production has come from the water-bearing sands in the deeper Lower Qishn interval, caused by leakage behind the casing due to a poor cement seal.

As a consequence the test results are believed not to represent the full oil production potential of the Nabrajah-2 well. The test has, however, confirmed the extension of the productive Qishn S2 sandstones to the northwest of the Nabrajah-1 discovery well, which flowed oil at a rate of 1,973 bopd.

The forward plan is to suspend the Nabrajah-2 well and move to the Nabrajah-3 appraisal location. Nabrajah-3 will test the extent of the oil-bearing Qishn S2 Sandstones approximately 1.1km northeast of the Nabrajah-1 location.
