Source: 8/24/2021, Location: Not categorized

Perth Basin oil producer Triangle Energy, on behalf of the Cliff Head Joint Venture, has advised that the CH-6 well at the Cliff Head Oil Field returned to production on the afternoon of 23 August 2021.

The Workover Programme of the CH-6 well completed the program of Electric Submersible Pump (ESP) replacement which included the installation of a new ESP in a more technically and cost effective configuration than previously adopted. All of the technical and well integrity expectations of the program were met and the well was handed over from well services to production on the 22 August 2021.

Performance testing and verification is currently underway, however the Company is pleased to announce that production associated with the CH-6 well is expected to stabilise at approx. 120 bopd, bringing the total field production to approximately 850 bopd.

The Company’s Hydraulic Workover Unit provider, Clear Cut Interventions (CCI), with the assistance of R&D solutions, succesfully deployed the first Omega Gemini plug on Slickline using a time delay hydrostatic setting tool in an offshore environment in Asia Pacific. Omega provided virtual training to the CCI supervisor due to COVID travel restrictions preventing a specialist being deployed to Australia.

The joint CH-6 and CH-11WI workover campaign provided the Company with the rare opportunity to evaluate the condition of the downhole completion and wellbore equipment with regards to long term well integrity and corrosion management.

Mr Robert Towner, Managing Director, 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.'
