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.

This paper describes how an exploration-and-production company successfully developed and applied a qualitative risk-based abandonment-prioritization strategy for an inventory of inactive subsea wells. -
DNV GL is introducing a new, risk-based recommended practice for performing and qualifying well abandonments titled DNVGL-RP-E103, Risk-Based Abandonment of Offshore Wells.

Many of the platforms in the North Sea are late in life, operating long past their initial design expectations due to costly life-extension work. Decommissioning has moved slowly, but the low price environment is likely to accelerate the trend.

Techniques for well-abandonment log evaluations have been studied in the Gulf of Mexico since 2012. The new methods described in this paper consist of adding nuclear sensors to supplement the acoustic measurements and introduce novel processing methods.

With the current low-oil-price environment, the cost of decommissioning is seen as a key driver for the ongoing economic viability of the basin.
