P&A Guideline from DNV GL could save the oil and gas industry more than USD32 billion

The plugging and abandonment (P&A) of offshore wells represents a significant cost to operating companies and national authorities. On the Norwegian Continental Shelf (NCS) alone, the cost is estimated to be USD108bn (NOK1870bn) over the next 40 years. Now a new DNV GL guideline will introduce a risk-based approach instead of the current prescriptive practice.
