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.

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.

This paper presents how one operator has developed a culture of circular decommissioning with the main goal of setting up a structured process to improve environmental performance by implementing the principles of a circular economy during decommissioning.
-
The final rule amends existing regulations and increases the level of financial assurances that operators must provide in advance.

Prior to proceeding with a contract to fulfil a rigless P&A campaign for Sasol in Mozambique, BiSN designed a field trial to prove the effectiveness of its bismuth plug technology. Although the technology had been used in 19 countries by BiSN for a variety of downhole applications, it had not yet been qualified for use in Mozambique.
