BassGas development

In October 2006, the BassGas Project was officially launched by the Premier of Victoria, Hon Steve Bracks MP. The Victorian Minister for Energy, Industries and Resources, Hon Theo Theophanous MP also attended the opening.

History

Development of the BassGas project began in 2001, lead by Origin and its original joint venture partners AWE, CalEnergy and Wandoo Petroleum Mitsui. Over a six year period, $750 million was invested by these companies to develop the Project.

This culminated in June 2006, when the Project was officially launched by the then Premier of Victoria, the Hon Steve Bracks MP.

Since then, BassGas has provided a significant supply of gas into the Victorian market. BassGas is designed to produce approximately 20 petajoules of sales gas per annum together with 1 million barrels of condensate and 65,000 tonnes of LP Gas.

Location

The Yolla offshore platform is located in 80 metres of water in the Bass Strait. Gas and liquids are extracted from a sandstone reservoir at over 3km in depth through two wells. Once extracted, the gas and liquids from the Yolla field are transported 150km via an undersea pipeline to the Lang Lang Gas Processing Plant 70 km South of Melbourne in Victoria. Here, the gas is processed for sale before being transported through the onshore underground gas pipeline to the Victorian Principal Gas Transmission Pipeline near Pakenham, Victoria.
