Plugging and abandonment (P&A) of offshore wells represents the highest cost within field decommissioning for operating companies and national authorities. 

DNV GL has now issued a new, globally applicable Recommended Practice (RP), on risk-based abandonment of offshore wells which in combination with optimized project execution and new technology could potentially reduce P&A costs by 30–50%. The framework outlined in the RP provides the possibility for individualized, fit-for purpose well abandonment designs, a contrast to the prescriptive methodology available in the industry today.
