HOUSTON, Aug. 31 -- DNO ASA, Oslo, has placed a sidetrack well on production in Tasour oil field in Yemen and expanded its 2006 drilling program for nearby Godah oil field.
DNO drilled the Tasour 22 sidetrack to 1,853 m TD and completed it in Cretaceous Qishn sandstone on a crestal structure on the eastern edge of the field. Initial gross production was 6,440 b/d of oil with 2,766 b/d of water.
The well's main wellbore determined that existing wells are effectively draining the Qishn reservoir in that part of the field.
DNO, operator of Block 32 with a 38.95% working interest, is moving a second, larger rig onto the block to drill the Tasour 23 wildcat, which will target a fractured basement prospect south of Tasour.
In Godah field, DNO will drill the Godah No. 3 appraisal and development well 14 km east of Tasour. It expanded the year's drilling program to drill a fourth Godah well.
The company expects to begin Godah production in the fourth quarter of 2006 at an initial rate of 2,000-4,000 b/d.
Development involves a 23-km, 10-in. pipeline to the Tasour central production facility, which will be expanded to handle Godah output. The pipeline and Tasour expansion might be in operation by mid-2007.
DNO has accelerated plans to acquire 275 sq km of 3D seismic data on the block, now planning to begin the survey this year. The survey will cover the area from the Godah discovery to the eastern boundary of Block 32 as well as a prospective area northwest of Tasour (OGJ, Mar. 13, 2006, Newsletter).
