Field Decommissioning & End-of-Field-Life Planning
This training covers end of field life planning and decommissioning. It works through economic limit determination and options for extending it, the cessation of production decision, well abandonment engineering and barrier requirements, facility and pipeline decommissioning options, cost estimation and provisioning, regulatory and liability frameworks, reuse and repurposing for storage or other service, and the planning and execution of a decommissioning programme.
Description
Decommissioning is a large, certain and late cost that is easy to defer thinking about and expensive to handle badly. It is also increasingly a live commercial issue: liability provisions affect balance sheets, security requirements tie up capital, transactions turn on who carries the obligation, and regulators are tightening both the standards and the timing. Planning for it from a position of understanding, rather than reacting to it when production ceases, materially changes both the cost and the options available.
This training covers the subject end to end. Economic limit determination is developed first, since when a field ceases to produce is a decision rather than an event, and options to extend it, cost reduction, water shut-off, infill, third party processing, ownership change, all defer the liability and add value. The cessation of production decision and its governance follow. Well abandonment engineering is then covered in detail: barrier requirements and their basis, permanent plugging design, cement placement and verification, sustained casing pressure, subsea and platform well differences and the cost drivers. Facility and pipeline decommissioning options, comparative assessment and their regulatory basis follow. Cost estimation, provisioning and security arrangements are then addressed, along with the regulatory and liability frameworks. Reuse and repurposing, execution planning, contracting and waste management close the training.
The largest lever on decommissioning cost is timing rather than method. Every year of continued production defers the liability, and deferral has present value that is often substantial relative to the cost of the measures required to achieve it. This inverts the usual view of late life investment: spending money to extend a marginal field's life is not only about the incremental production, it is about deferring a large certain cost. Evaluating late life opportunities without including this effect systematically undervalues them.
Wells dominate the cost in most decommissioning programmes. Permanent abandonment requires barriers that isolate every permeable zone from surface and from each other, verified to standards that have tightened over time, and achieving that in old wells with degraded cement, casing damage, sustained annulus pressure or incomplete records is where cost escalates. Wells that were plugged decades ago to earlier standards may require re-entry. Assessing the well stock early, well before cessation, is what allows the programme to be planned rather than discovered.
Facility removal options are subject to comparative assessment rather than to a single prescribed answer in most jurisdictions. Complete removal, partial removal, leaving in place, and toppling are evaluated against technical feasibility, safety, environmental impact, cost and other users of the sea or land, and the outcome varies by structure and by jurisdiction. Building the case for a derogation from full removal requires evidence assembled to a defined standard, and starting that work late constrains the options.
Finally, repurposing is now a genuine alternative for some infrastructure. Depleted fields and their wells and platforms are being assessed for CO2 storage, gas storage and hydrogen service, and pipelines for CO2 and hydrogen transport. This changes the decommissioning decision from a question of how to remove to a question of whether to remove, and it requires the assessment to happen before wells are plugged and structures removed, since those actions are irreversible
