Exedra, in conjunction with GEOLOG, introduces to the world, a novel P&A verification method, by applying a tracer gas below the Permanent Environmental Abandonment Plug barrier. The tracer gas will provide a sensitivity approximately 1000 times higher than today’s conventional pressure method. The introduction of an unambiguous, fast and sensitive verification method will pave the way for more cost-efficient P&A solutions which can be adopted to most plugging solutions and geometries. The technology has been developed in conjunction with Equinor Technology Ventures, ConocoPhillips, AkerBP and supported by Innovation Norway.
