Sydney-based Origin Energy Ltd.’s wholly owned Halladale and Speculant natural gas fields in the offshore Otway basin of Victoria have been brought on stream.
The joint development is expected to increase production at the company’s Otway gas plant near Port Campbell by as much as 80 terajoules/day.
The development involved directional drilling from land from a site about 30 km east of the town of Warrnambool to reach reservoirs 5 km offshore.
A 33-km pipeline was laid from the wellhead to connect to the existing gas plant.
Speculant field was discovered in 2014; Halladale in 2006.
The gas is being used for domestic supply.
