Decommissioning
The authors of this paper describe a system that enables the storage of renewable power while allowing for the optimization of time and expenditure for decommissioning of existing infrastructure.

A study of a limited number of decommissioned oil and gas wells in England found no evidence of methane leaks, including four wells found to be leaking in an earlier study.
One of the newest ways to plug and abandon wells and patch casing leaks involves an alloy that flows like water.

The deal grows the marine energy services company’s shallow-water GOM fleet by more than 30 vessels. -
Managed-pressure drilling has been associated as a technology used only on problematic wells and only as a last resort. However, when integrated at the beginning of operations as part of a comprehensive well plan, it becomes a performance-enhancing solution for any type of well classification, including development, directional, multilaterals, and horizontals.

A decommissioning project carried out by DOF Subsea on behalf of Repsol Sinopec Resources UK in the Central North Sea has achieved a 99% rate for the combined recycling and repurposing of recovered materials.

The DOI guidance explains how states can apply for the first $775 million in grant funding available this year under the Bipartisan Infrastructure Law to create jobs cleaning up polluted and unsafe orphaned oil and gas wellsites across the country.
-
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.
