BHP has approved US$520 million for its Longford Gas Conditioning plant joint venture project in Victoria.
It is part of a wider $1 billion invested into the project by BHP's fellow joint venture partners ExxonMobil and Santos.
According to BHP the project, in the Gippsland Basin, will add carbon dioxide removal capacity to the Longford Gas Plant, which conditions production from the group's Kipper, Tuna, and Turrum offshore development project.
The LGCP will be designed to process around 400 million standard cubic feet of gas per day and reduce CO2 content of treated gas to less than 3%, BHP says.
J. Michael Yeager, BHP's head of Petroleum, explained that "the Longford Gas Conditioning Plant is a necessary extension of Bass Strait infrastructure to enable valuable hydrocarbon liquids production and domestic gas supply for years to come".
The plant itself has been on the companies schedule for more than five years; however this is the first time the group has put a price tag on it.
Work is scheduled to start mid next year, and employ around 250 people.
