The company used its new DeepRange tool, in conjunction with its 7Series riserless intervention system, to isolate an outer annulus by circulating a minimum of 200 ft (61 m) of cement in place and pressure testing the plug as per BSEE regulation.
Martial Burguieres, Wild Well vice president of Marine Well Services, said: “This new technology and methodology will help operators reduce their subsea P&A liabilities as riserless operations represent dramatic cost reductions when compared to traditional subsea P&A operations.”
