Origin Energy has started gas production from the Halladale and Speculant fields in the Otway Basin in offshore Victoria, Australia.
The fields form part of the Halladale/Speculant project, which is 100%-owned by the company and is expected to increase production at the Otway Gas Plant by up to 80TJ/day.
Origin Integrated Gas CEO David Baldwin said: “Gas has a growing role both as a lower emissions replacement for coal and providing reliability to support growth in renewables and the Halladale/Speculant project will support that growing demand.
“Our strategy is connecting resources to markets and we are delighted that Halladale/Speculant will contribute to domestic gas supply and support the growth in renewables.”
The project is delivered in two parts and involved drilling from a land base 30km east of Warrnambool in a bid to access offshore reservoir locations 5km off the coast in the Otway Basin.
As part of the project, the new 33km Halladale/Speculant pipeline connecting the well site to gas plant was also constructed.

It forms part of the 4,000km long Jurassic-Cretaceous Australian Southern Rift System.
