Australia: Yolla-A Achieves Production Improvement

AWE Limited has been advised by the Operator, Origin Energy, that the Yolla-A platform has achieved significant production improvement as a result of successful well interventions and is currently producing gas at rates of approximately 57 Tj/day, up from 42 Tj/d that was achieved prior to the well intervention program.

Following the successful completion of a workover at Yolla-3 and wireline logging at Yolla-4, the Yolla-A platform is producing increased quantities of gas, condensate and LPG within the overall limitations of the platform’s fluid handling capacity.

The Managing Director of AWE, Mr Bruce Clement, said that the successful well workover at Yolla-3, completed in mid-April, was a positive step towards achieving this improved production performance.

“The Yolla-3 well was shut-in in late January 2013 after testing of the upper EVCM oil bearing zone was completed. The Joint Venture will have the opportunity to produce the upper EVCM oil and gas zone in Yolla-3 later in field life once gas compression and condensate pumping is installed on the Yolla-A platform,” he said.

“The Yolla-3 workover achieved its objective of removing an obstruction in the well bore that had prevented access to the well’s main gas bearing interval, the 2809 Sand. In addition, wireline logging at Yolla-4 identified opportunities for further production improvement that the Joint Venture is currently evaluating,” Mr Clement said.

Mr Clement added, “We remain confident in the long-term production potential of the BassGas asset. AWE will continue to work with the Operator of the project to maximise the potential of the asset and deliver value to our shareholders.”
