Oilex (LON:OEX) told investors that the drilling programme for the Cambay 77-H well is now ready to enter the ‘over-pressured’ section.
Cambay 77-H has been drilled to a depth of 1,652 metres, and Oilex said the condition of the wellbore was very good.
The rig is now preparing to drill ahead into the target reservoir section. The company says elevated gas readings are anticipated.
The well is located close to Cambay 76-H which was drilled and fracked before mechanical problems caused tesing to be suspended.
Operations on Cambay 77-H has also encountered some technical difficulties, but work is now clear to resume.
"Although drilling operations have been delayed due to a substantial system failure on Essar Land Rig #4, the 12 1/4 inch hole above the reservoir is now complete and secure behind casing,” said Ron Miller, managing director.
“The successful integrated stress test of the rig systems is reassuring and we now look forward to entering the target reservoir as part of the final hole section including the 350m horizontal length which will be fracture stimulated." Cambay 77-H will have a shorter horizontal section than Cambay 76-H, and will be completed with a conventional ‘plug-and-perf’ methodology.
