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.
Well abandonment is driven by economic decisions, when the production of an oil or gas reservoir ceases or ut gw zusmmr atfidlyjbe.
