Decommissioning
This paper reviews decommissioning and abandonment in Nigeria, looks at candidate identification strategies, breaks down the methods and best practices involved, and examines the requirements for openhole and cased-hole abandonment.
Carnarvon basin job will be McDermott’s largest decommissioning project to date.
Australia must insist on full removal when ExxonMobil decommissions the offshore project, the Wilderness Society has said.

Radioactive elements occur naturally at low levels in oil and gas basins. As oil and gas is extracted, these elements can accumulate in infrastructure. Now, scientists in Australia are investigating the toxicity of different radiation doses to marine organisms. -
This paper describes the operator’s culture of circular decommissioning, with the main goal to improve environmental performance by implementing circular-economy principles during the engineering and execution of decommissioning projects.
