Oil & Gas UK has published the second issue of its guidelines on the qualification of materials for the abandonment of wells.

Operations director Oonagh Werngren said: “These guidelines, aimed at well –operators, manufacturers and regulators, comprise the current industry expertise on qualifying materials for suspension and well abandonment.

“While cement is commonly used to safely seal and permanently abandon wells no longer used for exploration or development, the industry is developing and proposing new barrier materials including polymers, metals, grouts, rock formations, and composites.

“The industry requires that all new materials proposed for deployment in well abandonment fulfil certain criteria throughout the sequence of phases from development, qualification, production, storage, transport, and installation. These guidelines incorporate the latest industry expertise in the process to ensure the proposed material is qualified to perform the envisaged function.”

Issue 2 of The Guidelines on Qualification of Materials for the Abandonment of Wells will assist well-operators to comply with the UK Offshore Installations and Wells (Design and Construction, etc) Regulations (SI 1996/913), which lay down the standard that operators should achieve to prevent escape of fluids from a well on a permanent basis.
