Well plug and abandonment activity is currently the largest predicted spend in decommissioning. Ensuring well integrity after abandonment and removal of sea bed structures is necessary to prevent safety issues from well blowouts, environmental harm from leakage of hydrocarbons, or interference with other marine activities from wellheads after activities have ceased.
Information on notifications, authorisations and other activities relating to well P&A are found below
Operators must seek approval from OGA prior to abandoning a well. Given the potential costs of P&A activity and impact on MER, OGA are also particularly interested in P&A cost reduction strategies whilst meeting stringent criteria for protecting health and safety and the environment.
Well P&A consents Under the licence conditions (model clauses), the licensee is not permitted to commence, suspend or recommence drilling of any well or to carry out the completion or recompletion works, suspend or abandon any well without the consent of the OGA.

Notification to OSDR is required for P&A activities. No operations can begin before activity can be carried out before approval of the Wells Notification by the inspector and resolution of any objections.

Energy Pathfinder (previously known as Oil and Gas Pathfinder) has been relaunched by OGA. It provides information on emerging projects and business opportunities across decommissioning and energy transition activities, helping operators and supply chain identify cost effective solutions for project delivery.
