Santos, one of Western Australia’s largest domestic gas suppliers, today announced that first production from the Halyard-2 infill well has commenced.

The well is online six weeks ahead of schedule and is now producing. This will supply an incremental 65 mmscf/d into Varanus Island. Further, it will convert approximately nine mmboe of sales gas and condensate to 2P developed reserves.(1)

Santos Managing Director and Chief Executive Officer Kevin Gallagher said this is a valuable short-cycle capex project, delivering incremental low-cost volumes into the portfolio through to 2027, and supporting a reduction in unit production costs in 2025.

“This project demonstrates Santos’ commitment to our disciplined low-cost operating model and our focus on efficient execution of our projects and strong operational results in 2025,” Mr Gallagher said.
