Cooper Energy Limited (ASX:COE) is believed to be in talks with the APA Group (ASX:APA) to purchase the Orbost Gas Processing Plant. Expectations are that Cooper Energy will pay about $200 million for the asset, 375km east of Melbourne on the Victoria east coast. The two groups had formed a joint venture for the Sole Gas Project, comprising an offshore project to develop and connect the gas field managed by Cooper Energy and an onshore project managed by APA to upgrade the Orbost gas plant to process Sole gas for supply into the Eastern Gas Pipeline.
