Cooper Energy provides the following update to its previous advice of 8 May 2020 on the commissioning of the Orbost Gas Processing Plant. The gas plant is owned and operated by APA Group.
The gas plant is being commissioned to process gas from Cooper Energy’s Sole gas field for supply to
customers in south-east Australia. Completion of plant commissioning will enable commencement of the
field’s term supply contracts, and commencement of processing tariff payments by Cooper Energy to APA
The gas plant has proven its capability to produce sales specification gas from the Sole raw gas stream.
A total of 0.8 petajoules of gas from Sole has been processed and supplied into the Eastern Gas Pipeline
up to 21 May 2020 (inclusive).
APA, its technology provider and Cooper Energy have been working collaboratively to improve plant
performance to the level required for commissioning to be completed. This work included a shutdown of
the gas plant from 9 May to permit inspection, conduct maintenance and complete minor modifications
within the sulphur recovery unit.
The Sole reservoir and wells have performed consistent with expectations.
The shutdown work program was completed in full and plant operations resumed on 20 May 2020. Supply of Sole gas into the Eastern Gas Pipeline recommenced at approximately 8 pm on that day. Ongoing commissioning plans are to achieve a progressive, sustained increase in output rates whilst maintaining stable plant operation.
It is intended this be achieved gradually through a series of step changes whereby production rates are
increased, then maintained whilst plant operation is monitored and assessed prior to proceeding to the
next increment, with the ultimate target being 68 terajoules per day (TJ/day).
The plant is currently in the initial phase of this program, having maintained stable production rates equivalent to 28 TJ/day.
It is intended further update on the outcome of the commissioning program will be provided on completion
or as material developments occur.
