Triangle Energy kicks off Cliff Head workover campaign

Australia’s Triangle Energy has started a workover campaign on two wells on the Cliff Head oil field located offshore Australia following a four-month shut-in.

Triangle Energy said on Monday that the workover campaign on Cliff Head 6 (CH-6) and Cliff Head 7 (CH-7) wells started on Sunday, 25 October 2020.

The Hydraulic Workover Unit (HWU) arrived at the Cliff Head Alpha Platform (CHA) from Fremantle marking the start of the CH-6 and CH-7 workover campaign.

Over the coming month, the Electric Submersible Pump (ESP) system on both wells will be replaced, enabling the production from these wells to be restarted by year-end 2020.

The CH-6 and CH-7 wells have been shut in since June this year.

Production from the CH-7 well was shut-in as a precautionary measure during routine operational maintenance.

On the other hand, production from the CH-6 well was shut-in due to an ESP failure.

Triangle said that the execution of these workovers will return approximately 400 barrels of oil per day to Cliff Head’s production, taking total production to approximately 1000 barrels of oil per day.

Triangle Managing Director, Rob Towner, in crediting the work done by the Triangle Team and the JV partners over the course of 2020 to position the company to execute this complex programme, said: “Executing both workovers side by side is a significant opportunity for the company.

“Not only will we maximise operational efficiency through a streamlined work programme, we will bring forward production from both wells sooner than would have been the case if we’d executed both workovers separately”.

The Cliff Head oil field is located in the Perth Basin, about 270 kilometres north of Perth and 12 kilometres off the coast of Dongara in Western Australia.

The field resides in the Production License WA-31-L which covers 72km2, and the oil field covers 6km2 in the Commonwealth Exploration Permit WA-286-P. It is located at a water depth of 15-20 metres.
