Triangle Energy (Global) Ltd has brought the CH-6 well, part of the Cliff Head Oil Field in Western Australia, back into production.
The Perth Basin oil producer completed a workover at the field's CH-6 and CH-11WI wells on behalf of the Cliff Head Joint Venture, which it operates and retains a substantial interest in alongside fellow ASX-lister Pilot Energy (ASX:PGY) Ltd.
Conclusion of the workover marks the end of the electric submersible pump replacement, which included installing a new pump in a more technical and cost-effective configuration.
Performance testing and verification are underway, with the CH-6 well expected to stabilise at around 120 barrels of oil per day, bringing the total field production to roughly 850 barrels per day.
“An excellent outcome”
Triangle Energy managing director Robert Towner said: “Well integrity management is a priority at Cliff Head and the condition of the recovered equipment from both the CH-6 and CH-11WI wells showed no visible evidence of corrosion or physical degradation.
“This is an excellent outcome considering the years since this equipment was installed and supports our plans to continue to extend the operating life of the facility.
“The company looks forward to future well activities and exploring asset life extension opportunities.”
Workover complete, production resumes
The Cliff Head Oil Field’s CH-6 well returned to production on Monday afternoon, with subsequent testing now underway.
Before its restart, all of the program’s technical and well integrity expectations were met, so the well was handed over from well services to production on August 22.
Triangle’s hydraulic workover unit provider, Clear Cut Interventions (CCI), with the assistance of R&D solutions, successfully deployed the first Omega Gemini plug on Slickline using a time delay hydrostatic setting tool in an offshore environment in the Asia Pacific.
Omega provided virtual training to the CCI supervisor because COVID-induced travel restrictions prevented a specialist from being deployed to Australia.
Ultimately, the joint CH-6 and CH-11WI workover campaign provided Triangle with the rare opportunity to evaluate the condition of the downhole completion and wellbore equipment in terms of its long-term well integrity and corrosion management.
Exploring Cliff Head and beyond
Triangle is the registered operator and holds a substantial interest (78.75%) in the Cliff Head Oil Field, which includes the onshore Arrowsmith Stabilisation Plant and offshore Cliff Head Alpha Platform.
Current oil production at the field is around 800 to 900 barrels of oil per day gross, with the company poised to leverage its operating expertise and infrastructure to secure growth opportunities in the basin beyond the Cliff Head Joint Venture.
Triangle’s growing footprint in the Perth Basin includes a 45% joint venture interest in the Xanadu-1 prospect within the TP/15 Xanadu oil field and a 50% participating interest in the PL7 production licence, including the Mt Horner oil and gas field.
Beyond the Perth Basin, Triangle holds a 27.67% equity interest in fellow ASX-lister State Gas Ltd (ASX:GAS), which is developing the Reids Dome Gas Project in Queensland to supply a gas shortage in the eastern states.
