📋 Tender Overview
Scope of Work:
To Develop Equus gas-condensate fields offshore Western Australia.
Description:
Privately held Western Gas Corp. Pty. Ltd., Perth, has completed a basis of design for development of its wholly owned Equus gas-condensate fields offshore Western Australia and is now looking for a project development partner.
Western Gas acquired the fields from Hess Corp. in November 2017 and vowed to develop the fields as a new domestic gas supply for Western Australian industry, along with business and household customers in the state.
Western Gas is currently looking for a development partner for the gas and condensate project, as well as customers for the gas produced by the project. The company is expected to make the final investment decision on the project in late-2019 with first production targeted for 2023.
The project comprises gas-condensate fields within four permits and one retention lease, namely WA-390-P, WA-474-P, WA-518-P, WA-519-P, and WA-70-R, which have an independently certified resource in excess of 2 tcf of gas and 42 million bbl of condensate.
The fields are in the Carnarvon basin about 200 km northwest of Onslow and were discovered by Hess during 2008-12. The company drilled 16 wells that resulted in 14 successes in eight main fields. An estimated $6-billion (Aus.) investment was envisaged to bring the project to fruition with a plan to feed the gas into the Woodside Petroleum Ltd.-led North West Shelf gas facilities on the Burrup Peninsula.
However, the project came off the boil in 2016 because of the downturn in global oil prices and the high capital costs of development in Australia.
In early 2017, Hess decided to write down the full value of the proposed project by $933 million (Aus.) and focus its attention on the Bakken shale in the US, Valhall field offshore Norway, and Liza field offshore Guyana.
Hess awarded the FEED contract for the topsides and floating facilities of the project to INTECSEA and WorleyParsons.
Neptune Marine Services was contracted by Hess to complete the geotechnical and geophysical surveys for the project. The company completed the survey under a strategic alliance with Greatship Subsea Solutions Australia.
Wood Group was chosen by Hess to provide engineering services for the subsea and pipeline infrastructure of the project.
DORIS Engineering was awarded a contract to carry out the conceptual engineering studies related to the subsea development of the project.
