Origin Energy Limited (Origin), as Operator of the BassGas Joint Venture, today confirmed that the Yolla offshore platform has returned to free flow production mode, onshore operations at Lang Lang have restarted and BassGas has recommenced supplying gas to south east Australia.

Production at BassGas had been suspended since late 2011 for the Mid Life Enhancement project, the first phase of which involved upgrading Yolla from an unmanned to a manned platform and installing export compression and condensate pumping modules.

Installation and commissioning of the accommodation module has now been successfully completed. As previously advised, the initial attempt to install the export compression and condensate pumping modules was not successful and a summer 2012/13 installation program was being evaluated.

A decision has been taken not to install the export compression and condensate pumping modules over summer 2012/13. The equipment will be stored and maintained ahead of installation at a later date, to be determined by the joint venture.

As a result of these decisions and with the return to free flow production complete, the chartered installation vessel will be demobilised.

Origin Chief Executive Officer Upstream, Mr Paul Zealand said, "The return of Yolla to free flow production signals the completion of infield activities for the current program. The joint venture is currently reviewing the timing and sequencing of development drilling and installation of export compression and condensate pumping modules, the outcome of which will be advised at a later date."

  • AWE Limited (through subsidiaries): 46.25%
  • Toyota Tsusho Gas E&P Trefoil Limited:
  • (i/o Toyota Tsusho Gas E&P Trefoil Limited) 11.25%
