Plug & abandonment

Many of Statoil’s fields on the Norwegian continental shelf (NCS) are reaching the end of production. More than 1000 wells need to be abandoned due to field decommissioning over the next 5 to 25 years. Of these, almost half are subsea wells.

When the production from a well is no longer profitable, there are two options available: Either permanently plug and abandon (P&A) the well and remove the wellhead, or re-use the slot by plugging the mother well and sidetrack a new wellbore (also known as slot recovery). The purpose of P&A is to establish permanent barriers to prevent migration of hydrocarbons to the surface.

With the impressive scope ahead us we need new approaches, new ideas, new solutions. Maybe technologies already exist that we are not aware of? Maybe there exists solutions in other kind of businesses that fit our needs perfectly? Maybe your new, intriguing out-of-the box idea is what we need?

We are looking for new technology and methods which can improve and simplify P&A and slot recovery operations:

  • More efficient methods for pulling/removing casing strings in slot recovery
  • Alternatives to section milling for creating annulus barriers
  • Alternative materials for annulus barriers
  • P&A without cutting and pulling the tubing and casing
  • P&A of subsea wells without a rig
  • Logging through multiple casings
  • Preventing leak paths from e.g. control cables
  • Optimum well construction for future P&A
