Decommissioning

A recent mission that saw the robot submarine Autosub Long Range, better known as "Boaty McBoatface," explore and visually map end-of-life oil fields has been hailed as a success.

Britain’s North Sea Transition Authority is removing the requirement for offshore operators to submit Cessation of Production reports when preparing to abandon a field.

Bob Pearson shares his thoughts on the repurposing or abandonment and decommissioning of wells that are unlikely to be repurposed or pose an environmental risk with emissions into the atmosphere or aquifers.

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.
