Successful Demir Dagh-7 test results confirm high productivity well
CALGARY, Oct. 30, 2014 /CNW/ - Oryx Petroleum Corporation Limited ("Oryx Petroleum" or the "Corporation") today is pleased to announce an appraisal drilling update for the Demir Dagh field in the Hawler license area in the Kurdistan Region of Iraq, including test results for the Demir Dagh-7 and Demir Dagh-8 appraisal wells ("DD-7" and "DD-8", respectively). Oryx Petroleum is the operator and has a 65% participating and working interest in the Hawler license area.
- Demir Dagh-7 Test Results
- Testing of an interval in the Shiranish and Kometan formations in the Cretaceous reservoir
- Achieved a maximum sustained natural flow rate of approximately 3,300 bbls/d of oil over a period of 6 hours restricted by a 48/64" choke
- Demonstrated high productivity comparable to the Demir Dagh-2 ("DD-2") well with expected production rate to exceed 5,000 bbls/d once the well is completed with an electrical submersible pump ("ESP")
- Encountered similar crude qualities as tested in other wells in the Cretaceous reservoir in the Demir Dagh field (20 to 22° API)
- Demir Dagh-8 Test Results
- Observations and data collected during drilling were similar to the DD-7 well but mechanical failure in isolating the perforation interval resulted in an unsuccessful test
- A short sidetrack well is planned to be drilled and the Cretaceous reservoir re-tested in late Q4 2014 or early 2015
- Demir Dagh-9 and Demir Dagh-10 Appraisal Wells
- The Demir Dagh-10 ("DD-10") well was spudded last week with drilling and testing expected to be completed in Q4 2014
- The Demir Dagh-9 ("DD-9") well is to be spudded in the coming weeks with drilling and testing expected to be completed in Q4 2014 or early 2015
- Acquisition of 3D Seismic Data
- The acquisition of 223 km2 of 3D seismic data covering the Demir Dagh structure and the Banan structure east of the Zab River was recently completed
Commenting today, Henry Legarre, Oryx Petroleum's Chief Operating Officer, stated:
"We are very pleased with the progress we have achieved in the development of Demir Dagh, including the test results of DD-7 which successfully flowed oil from the well´s primary target in the Cretaceous. The test demonstrated a productivity similar to DD-2 and we expect it to have comparable productive capacity once completed with the aid of an ESP.
While the drilling of DD-8 was achieved ahead of schedule and under budget, and exhibited the same characteristics as DD-7, we were unable to successfully flow oil from DD-8 due to a mechanical failure in isolating the testing zone. We had moved the rig off to drill DD-10 while testing DD-7 and DD-8, but plan to return with an ESP for DD-7 and a short sidetrack for DD-8. We intend to re-test the Cretaceous in DD-8 and all indications suggest that it has the potential to become a high productivity well similar to DD-2 and DD-7.
Overall, we are very pleased that improvements in the security environment have enabled us to resume activities in a large portion of the Hawler license area."
Demir Dagh-7 and Demir Dagh-8 Test Results
Following completion of the testing program on the Demir Dagh-6 well in early July 2014 the EDC Romfor-22 drilling rig spudded the DD-7 development well. DD-7 was drilled near the crest of the Demir Dagh structure in a northerly direction through the main east-west fault. The DD-7 well reached total measured depth of approximately 1,900 metres in the Cretaceous reservoir. Upon reaching total depth the rig was moved to spud DD-8. DD-8 was drilled from the same wellpad as DD-7 but in a southerly direction away from the main east-west fault. The DD-8 well reached total measured depth of approximately 1,900 metres in the Cretaceous reservoir in late September 2014. The primary objective of both wells was to increase wellhead production capacity. Technical data collected and observations during drilling of both wells, including significant losses of drilling fluids, suggested the presence of hydrocarbons, a highly permeable and connected fracture network, and matrix porosity comparable to other wells drilled at Demir Dagh.
The completion test conducted at the DD-7 well in a 65 metre interval of the Shiranish and Kometan formations in the Upper Cretaceous reservoir successfully flowed oil at an average rate of 3,300 bbls/d over a period of 6 hours restricted by a 48/64" choke size under natural flow conditions. The crude oil tested was measured on site between 20° and 22° API gravity, which is similar to crude measured in the Cretaceous formations tested at the DD-2, Demir Dagh-3 ("DD-3") and Demir Dagh-4 ("DD-4") wells. Quantities of natural gas and hydrogen sulfide were encountered comparable to those encountered at the DD-2, DD-3 and DD-4 wells with natural gas measured at between 40 scf/bbl and hydrogen sulfide at 0.4% in the natural gas phase. The test demonstrated productivity comparable to that observed at the DD-2 well and the well will be completed as a producer well. No water production or pressure decline was observed during the test. Works to tie-in the well to the production facility are in progress and expected to be completed in Q4 2014. The well is expected to produce under natural flow conditions until early 2015 when an ESP is expected to be installed at which time the production capacity of the DD-7 well is expected to exceed 5,000 bbls/d.
The drill stem test conducted in the Shiranish and Kometan formations in the Upper Cretaceous reservoir at the DD-8 well was unable to successfully flow crude oil from the well. Oryx Petroleum attributes the unsuccessful test to a mechanical failure in properly isolating the interval tested. In late Q4 2014 or early 2015 the Corporation plans to drill a short sidetrack well at DD-8 and re-test the Cretaceous formations before completing it as a producing well.
All field fluid measurements at the DD-7 well will require laboratory analysis to confirm results and should be considered preliminary until such analysis has been done. The aforementioned test results are not necessarily indicative of long-term performance or of ultimate recovery.
Remaining 2014 Demir Dagh Appraisal and Development Drilling
In late October 2014 the EDC Romfor-22 rig spudded the DD-10 development well. The DD-10 well is being drilled to the north of the main east-west fault and its primary objective is to build productive capacity. The KS Discoverer-1 rig, previously drilling at the Ain Al Safra field, is expected to spud the DD-9 development well in the coming weeks. The DD-9 well is being drilled from the DD-3 wellpad in the eastern portion of the Demir Dagh structure and its primary objectives are to provide additional information regarding the oil-water contact in the Cretaceous reservoir and to build productive capacity. The drilling and testing of the DD-10 well is expected to be completed in Q4 2014 and the drilling and testing of the DD-9 well is expected to be completed in early 2015. The next well in the Demir Dagh development sequence is expected to spud before the end of 2014 with continued development drilling throughout 2015.
3D Seismic Data Acquisition
The acquisition of approximately 223 square kilometres of 3D seismic data over the Demir Dagh structure and the Banan structure east of the Zab river commenced in June 2014 and was recently completed. The 3D seismic data is expected to provide additional information to further refine development plans. 3D seismic data covering the Zey Gawra structure and the Banan structure west of the Zab river is planned in the second half of 2015 provided there are improvements in the security environment.
