Oil & Gas

Upstream, midstream and downstream – onshore receival, decontamination, decommissioning and disposal of late-life oil and gas assets.

The Challenge

Australia’s offshore oil and gas inventory is in a sustained decommissioning cycle. Bass Strait fields are winding down; North West Shelf and Carnarvon basin platforms face cessation-of-production decisions; retired refineries and downstream distribution infrastructure is increasingly approaching end of life with the resultant legacy environmental liabilities needing to be managed with sensitivity. Regulatory and reputational exposure is a material factor for Operators as they transition to a sustainable future.
