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.
