Origin Energy Ltd., Sydney, has let a $1.3 million (Aus.) contract to Wood Group Kenny for provision of a detailed engineering design for the onshore pipelines related to Halladale, Black Watch, and Speculant natural gas fields in the Otway basin just offshore western Victoria.
The three fields are in inshore Victorian state waters and because of nearby sensitive marine environments the development wells are being planned with wellheads on land using extended-reach drilling technology to reach reservoirs offshore.
The wells will be tied back to the existing Otway gas plant near Port Campbell.
The work involves detailed design of onshore raw gas and mono-ethylene glycol pipelines from the well site to the gas plant.
Construction is scheduled to begin by yearend.
Speculant-1 wildcat was drilled in 2014 and found a 145-m gas column close to previously discovered Halladale and Black Watch fields. The development program incorporating all three discoveries was approved in October 2014.
Gas produced will be sold into the Victorian domestic grid.
