CAMBAY-77H Well - Fracture Stimulation Operations Complete
· All stages have been successfully fracture stimulated
· Elevated overpressure remains ~ 5,000 psi
· Preparing site for milling out plugs
Oilex Ltd (ASX: OEX, AIM: OEX) is pleased to announce that fracture stimulation operations have been completed at Cambay-77H. The 4 stages have been successfully completed and preparations are underway for mill-out operations to remove the plugs and open all 4 stages to the well bore.
Since the previous update on 2 July 2014:
ü Stage 3 and 4 were successfully frac'ced
ü ~20,000 bbls of frac fluid and ~550 tonnes of sand were used in the operations
Currently the frac equipment is being demobilised and the site is being prepared for the plug mill-out using the coiled tubing unit, which has successfully supported frac ops to date. As previously reported, subsequent to Stage 1 activities, gas was detected at surface and elevated overpressure of ~5,000psi was measured indicating a pressure increase of 670psi. The original reservoir pressure of ~4,330psi was interpreted from the micro frac programme. No decrease in the elevated overpressure has been noted and the reservoir section has responded to all fracs in a similar manner.
In addition to preparing for mill-out operations, previously mobilised well testing equipment is being positioned and commissioned at site. This equipment will be used during flowback and production testing.
Managing Director of Oilex, Ron Miller, said;
"We are very pleased with the reservoir response to fracture stimulation on all 4 stages. Importantly, Cambay-77H had indications of gas during frac ops, highlighting the possibility of excellent reservoir deliverability. Oilex is looking forward to successful mill-out operations and production testing after sufficient frac fluid has been recovered from the well."
