Decommissioning
Helix Energy Solutions will start work on a five-well complete abandonment project in the offshore Tui field in late 2022.
The survey was part of a project led by the University of Aberdeen, looking at the effects of decommissioning oil and gas structures on marine ecosystems.
The UK’s Net Zero Technology Centre looks to pave the way for new well P&A technologies to be tested, trialed, and brought to market quickly.

Decommissioning decision makers often need to determine the best and most practicable options for pipelines, flowlines, and power cables, including leave-in-place strategies or removal. This study presents results from several evaluations using advanced methods to support the determination of options. -
These four technical papers provide an overview of how facility decommissioning is addressed these days, including a case study in east Asia and a discussion of what to do with pipelines, flowlines, and umbilicals to preserve the environment—should they stay, or should they go?

This paper reviews the existing planning process for decommissioning projects on the UK Continental Shelf and explores an alternative approach using the facility removal date instead of the cessation of production date.

This paper discusses various best practice technical strategies for decommissioning which can be applied in the Southeast Asia region, and throughout the world. The strategies proposed can result in an estimated operator saving of more than 30% over the entire decommissioning execution expenditure. The processes discussed are included in the typical steps of prelimina…

When done well, planning for closure serves as a foundation for sustained socioeconomic well-being, beneficial reuse of project assets, and accountable decision-making. This ultimately contributes to an operator’s social license.

The Heerema semisubmersible crane vessels Thialf and Sleipnir were used on the job to remove the 36,000-ton structure.

The impact of orphan wells, both on the environment and on tightening budgets, is a growing concern in the industry. Boom times result in a vast uptick in wells drilled. In bust times, when companies disappear, the liability outlook for these probes gets murky and federal and state governments start looking for answers.

The paper explores the biology of the invasive Tubastraea sun coral, aiming to identify methods to eliminate or diminish its spread.

Expressions of interest released by the operator include everything from abandonment to life extension.
