Decommissioning
This paper identifies opportunities and risks associated with repurposing an offshore oil and gas platform for green hydrogen production. Various technical scenarios were investigated for the case study platform, and their profitability was determined using economic calculations. In addition, all the submodels were compared with standard decommissioning costs for reco…
This paper presents an approach for safe, efficient, and cost-effective legacy well reabandonment.
This paper uses the structural-integrity-management framework to evaluate the current structural integrity of chosen platforms, highlighting their potential and limitations for carbon capture, use, and storage purposes based on in-service assessments.

The 2014 SPE Annual Technical Conference and Exhibition (ATCE) in Amsterdam drew people from all over the world, covered global themes, and focused on the triumphs, challenges, and remaining opportunities for the North Sea. -
Well plugging and abandoning on a limited budget is a lofty goal that forces the industry to consider new ways and new materials. Cost-effectively dealing with this global problem will require developing tools to carry out the decommissioning without bringing in a drilling rig.
-
While decommissioning is not new, the need is accelerating, along with cost and regulatory requirements. A panel at ATCE discussed the challenges in executing decommissioning projects.
-
A strong reason for removing old platforms from the Gulf of Mexico, rather than trying to squeeze more years of marginal production out of them, is hurricanes.
-
Much of the new technology development occurring now is aimed at finding better ways to sever the thick, tough steel structures and wellheads so that they can be removed.
-
When he started his firm focused on removing obsolete offshore structures, Brian Twomey chose the name: Reverse Engineering Services. The thinking was that taking out a structure is like building it, but in reverse.
-
Decommissioning costs are often made higher by decisions made during the initial engineering and construction stages of an offshore oil or gas field. Designing with a critical eye can go a long way toward reducing the decommissioning costs, which occur decades later.
-
Industry perceives decommissioning projects as more risky and uncertain than capital projects. Several recent decommissioning projects delivered in an immature marketplace seem to support this view.
-
Advances in modeling techniques allow quantitative prediction of long-term trends in cuttings-pile characteristics and environmental risks, providing firm direction in mitigating risks.
-
The great majority of wells do not pollute.
