Peat GPF1 Pond Remediation and Oily Water Project

The Peat field is located on the Petroleum Lease Tenure PL101, 73km north of Miles and 18km north-east of Wandoan. It produces approximately 9 TJ/day of gas that feeds in to the Roma Brisbane pipeline from 24 operational wells.

Peat facilities include a gas plant and a remote field compressor station 4km south of the GPF at well Peat#12 for the southern wells. The contract comprised a new Oily Water Separator tank, temporary pipelines to bypass the existing Interceptor pit, new interceptor solutions and remediation and backfilling.

York Civil was engaged by Origin Energy to decommission the GPF1 Pond. The process required pumping out the water and sludge and removing the existing HDPE liner. Scope of works included the installation of a large underground tank, underground drainage and construction of the new pump station concrete work, pipework and pumps.

York Civil also undertook the construction of new concrete bunds and slabs for the new oily water system, installed a new oily water separation system including the associated pipework and pumps, and demolished the existing oily water system.
