Decommissioning
This paper identifies opportunities and risks associated with repurposing an offshore oil and gas platform for green hydrogen production. Various technical scenarios were investigated for the case study platform, and their profitability was determined using economic calculations. In addition, all the submodels were compared with standard decommissioning costs for reco…
This paper presents an approach for safe, efficient, and cost-effective legacy well reabandonment.
This paper uses the structural-integrity-management framework to evaluate the current structural integrity of chosen platforms, highlighting their potential and limitations for carbon capture, use, and storage purposes based on in-service assessments.

The COVID-19 disaster and a catastrophic fall in oil prices could leave the state on the hook for billions in environmental cleanup costs if oil and gas companies go bankrupt during the health crisis, New Mexico's top land official says. -
Even before the global pandemic impacted markets, decommissioning work in the North Sea region was expected to increase. Global decommissioning projects could reach $42 billion by 2024.

Developing an asset requires key investment decisions to be made early in the process, and as a result, some critical cost evaluations—such as abandonment—are often ballpark estimates. Adjusting the parameters for evaluating these costs can lead to more-accurate project valuations.

Across the West, thousands of oil and gas wells sit idle on federal lands, and many are orphaned with the companies that drilled them now defunct. These orphaned wells can pose environmental and safety hazards, but, as critics note, the Bureau of Land Management does not have a good way of tracking
