Overview

Since WA Oil production commenced in 1967, onshore production wells gathered oil from the field beneath Barrow Island.

Processing of the oil occurred on the island before being transported via pipeline to offshore tankers for export. Over nearly six decades of production, WA Oil produced more than 335 million barrels of oil and delivered more than $1 billion in revenue to government.

The retirement of WA Oil is set to be one of the largest and most complex petroleum decommissioning projects to be undertaken in Australia.

Given the age of the WA Oil infrastructure and historical oil field practices, it is recognised the decommissioning process will present unique challenges. However, with capabilities gained from the successful decommissioning of the Thevenard Island oil facility and support from a team of global experts, Chevron has the expertise and experience needed to carry out the decommissioning safely and manage environmental risks.

To support decommissioning of the WA Oil facilities, a range of activities are planned to take place.

Stage 1 of the project will be undertaken between 2025 and 2031. It includes the plugging of ~888 wells and the decommissioning and removal of infrastructure including separator and waterflood stations, ~1500km of pipelines and flowlines, ~570km of roads, terminal tanks, a ~10km loading line, historical accommodation facilities, and power, water and waste facilities. Stage 2 of the project will focus on remediation, landforming and rehabilitation.

The decommissioning of WA Oil marks the end of an important chapter in Chevron history, as it continues to deliver natural gas from the Gorgon and Wheatstone facilities and looks to new energy opportunities for a lower carbon future.

Opportunities listed below are for Chevron Australia Pty Ltd packages, specifically for WA Oil decommissioning.
