Equus Energy has locked in two main tie-back routes, both designed to supply LNG export and the WA domestic market.

The first option ties back to Woodside’s Pluto, providing access to Pluto LNG Train 1, the Karratha Gas Plant and the domestic market through the Dampier to Bunbury pipeline.

The second option connects to Santos’ Varanus Island gas plant, utilising existing North West Shelf infrastructure and WA pipelines for LNG and domestic gas supply.

Managing director Will Barker says Pre-FEED has reduced complexity and risk, allowing Equus to focus on commercialisation, partnerships, and preparations for FEED.

“What continues to stand out about Equus is the ability to leverage existing North West Shelf infrastructure and spare gas processing capacity to access both LNG export markets and the Western Australian domestic gas market,” he said.

“At a time when WA is facing tightening domestic gas supply and Asian buyers continue to focus on long-term energy security, Equus is positioned as a new source of reliable Australian gas supply for the region.”

Equus is advancing approvals for its preferred plan, which ties subsea wells to a permanently moored FPSO, stabilises condensate for export and routes dry gas into existing processing infrastructure.

The company has conditional consent for an 85% LNG export and 15% domestic gas split, with no major approval barriers identified.

By using spare capacity instead of building new infrastructure, Equus aims to keep execution risk and capital costs under control.

Reservoir models support the plan, with Equus targeting 350MMscf/d from up to five subsea wells to supply up to 50TJ/d of domestic gas, 2Mtpa of LNG and 12,000bbl/d of condensate at start-up over an estimated 15-year life.

The timing is favourable, with WA domestic gas supply tightening as legacy fields decline and Asian LNG buyers focused on long-term security.

Being located within existing North West Shelf infrastructure is central to the project, giving Equus a clearer path to commercialisation as new gas supply becomes harder and slower to bring online.

With technical work advanced, Equus is now focused on partnering and commercialisation ahead of FEED and FID.

The company is in discussions with upstream partners, LNG buyers, domestic gas customers, infrastructure owners and financiers.

This milestone moves Equus beyond concept framing into a more advanced stage, with development pathways, market access and commercial plans now aligned around a defined project.
