ExxonMobil Corp., Irving, Texas, (NYSE: XOM) reports that the Gippsland Basin Joint Venture, which includes its subsidiary Esso Australia, will invest $1.1 billion to develop more than 270 million oil-equivalent barrels from the Turrum Field in the Bass Strait, offshore southeast Australia.

The development follows the recent announcement of $1 billion in funding to develop natural gas from the Kipper Field, also in the Bass Strait.

Esso Australia is the Turrum field operator and holds 50% interest with BHP Billiton. Esso Australia operates 21 offshore oil and gas production facilities in Bass Strait and also operates and holds 32.5% interest in the Kipper Unit Joint Venture with BHP Billiton and Santos Ltd.

“ExxonMobil continues to be an industry leader in bringing new energy supplies to the market and the Turrum Field development is the latest example,” says Rich Kruger, president of ExxonMobil Production Co. “Bass Strait has a long history and a bright future. There are significant oil and gas resources remaining to be produced in the basin.”

He adds that Esso Australia has produced oil and gas from the Bass Strait offshore fields for nearly 40 years. The Turrum and Kipper projects are among 119 in ExxonMobil's industry-leading portfolio to support development of more than 24 billion oil-equivalent barrels of energy.

Kruger says the Turrum field holds about 1 trillion cubic feet of gas and 110 million barrels of oil and natural gas liquids. The development concept for the project is based on the construction of a new platform-bridge linked to the existing Marlin A platform in Bass Strait. The platform will process additional oil and gas cycling which will be piped back to existing processing facilities at Longford. Construction is expected in 2009 with first oil production in 2011, and first gas sales in 2015.

He adds that the Kipper field holds about 620 billion cubic feet of recoverable gas and 30 million barrels of condensate/liquefied petroleum gas. The Kipper field will be developed by the installation of a number of subsea wells, piped back to the existing infrastructure at Longford. Construction will begin this year and first gas is expected in 2011. JAS
