DNO produced oil during the test in Nabrajah No. 5. The final results from the test using an electrical submersible pump were 5,800 b/d at 38.6° API, 252 b/d of water, and 4,162 Mcf/d of gas.

After a pressure build up test, the well was flowed without downhole pump, and produced 2,812 b/d of oil at 41.9° API, 153 b/d of water, and 3,054 Mcf/d of gas.

Based on the test results, DNO believes that the capacity of the well is higher than what has been achieved from the test.

Basement is also producing in the neighboring blocks (block 14 operated by Nexen and block 10 operated by TotalFinaElf), and production rates of up to 10,000 b/d have been observed.

Following the test in the basement interval, the overlaying Kohlan dolomites will be tested. In this interval strong hydrocarbon indications were also observed while drilling. Furthermore, evaluation of electrical logs indicates the presence of hydrocarbons in a 42 m gross interval in the Kohlan dolomites. The observations of heavier hydrocarbon components during drilling indicate that the hydrocarbons are oil. However, testing is required to confirm the nature of these hydrocarbons.

DNO is the operator of block 43 holding a 56.67 % working interest.
