DNO Highlights Middle East, Africa Drilling Ops
DNO International has released an exploration and ongoing drilling report for its assets in the Middle East and Africa.
Rig 905 was moved from block 47 to block 32, to drill the Tasour-17S development well. The well did not encounter hydrocarbons, and the well was subsequently plugged and abandoned. The rig was moved to drill Godah-10 development well, which has now been completed as an oil producer.
Following the Nabrajah-18 well , Rig 908 was moved to the eastern part of the Block to drill the Suwehed-1 exploration well. The well has now reached its total depth of 1,566 meters. The well penetrated the Qishn target deeper than prognosis and indications of hydrocarbons were encountered in the top of the Qishn reservoir. The
well was not tested and further evaluation of the Suwehed structural complex will be undertaken prior to deciding on the drilling of additional wells on this structure.
On the Yaalen-1 discovery well, the test program was completed and the well was temporarily abandoned August 29, 2008. Oil was confirmed by wire line fluid sampling both in Yaleen-1 and Yaleen-2. However, due to inconclusive test results from both these wells, the Yaleen area will be re-evaluated after completing a 3D seismic survey. Contingent on the results from this evaluation re-entry of the wells for further testing will be considered. The Rig 900 has now been re-located to block 53 to undertake work over operations.
As previously reported the Sharnah-1 exploration well, which was drilled on another structure in Block 47, flowed 600 bopd during testing and was thereafter completed as a potential future production well.
Rig 919 drilled and completed the Bayoot-6 exploration well June 17 to August 29, 2008. The well encountered oil in the Basement and has been completed as an oil producer. The rig was then moved to the Raoq-1 exploration well location, to drill a different Basement structure to the south of the Bayoot area.
KURDISTAN REGION OF IRAQ
Tawke PSC area
The Sindy rig completed the Tawke-10 appraisal well as a future oil producer, after which the rig was moved to Tawke-9 well location. The Tawke-9 well was spudded August 23, 2008. The well is now completed as a future oil producer, without prior testing.
The Tawke-15 well is being drilled as a combined Cretaceous delineation well and Jurassic/Triassic exploration well. Drilling has taken longer than planned and the well is expected to penetrate the Jurassic interval during the coming weeks.
Erbil PSC Area
The Hawler-2 well is primarily targeting Jurassic and Triassic intervals to further explore the oil discovery in Hawler-1 well. A 7' liner is now installed into the Jurassic interval which produced 9,000 bopd from a test in Hawler-1. The forward plan is to further deepen the well into the lower Jurassic and Triassic intervals, and
then temporarily abandon the well. As the reservoir pressure is likely to by higher than originally expected equipment with higher pressure rating is required. Therefore testing of the well is planned to be undertaken at a later stage.
The 3D survey across the Hawler structure has now been completed. This together with the well results will form the basis for the evaluation of the resource potential and the forward plans for the Hawler oil discovery.
It should be noted that the name 'Hawler' is likely to be replaced with another name for this structure in the future, but the new name is yet to be decided.
The Sangussi-1 exploration well was spudded on July 4, 2008. The well reached the planned total depth without encountering hydrocarbons and the rig was released from DNO. Further technical work and prospect
evaluation is currently undertaken to investigate additional prospects potential within this large Block.
