The well was drilled to a total depth of 1,530m and intersected the Qishn formation at 1,369m.

Based on drilling and petro-physical data, the well encountered 15m of gross oil pay (10.5m net) with 25 per cent porosity.

The well has been equipped with a down-hole pump and placed on production at a restricted rate of approximately 250 bpd of crude oil.

Initial field tests of oil quality estimate the crude oil gravity at 19 degrees, which is to be confirmed by laboratory analysis.

Consistent with other Qishn wells, the well will require some time to clean-up before diverting production to the central treating facility.

The company plans to drill an appraisal well in the reservoir in order to establish the size of the new pool.

The drilling rig is being moved to the next prospect on the plateau, Ras Nowmah North, which is expected to spud in the next two weeks.
