Decommissioning Group

Influencing Decommissioning​

  • Deliver 35% cost reduction in decommissioning​
  • Guidance for future use​
  • Environmental Impacts of well decommissioning and decommissioned wells

KPIs (Specific, Measurable, Achievable, Relevant, Time-Oriented)

  • Reduce well decommissioning cost by >35% (ref 2015 base case)

Scope

  • All existing and future platform and subsea wellbores currently registered on the
  • OGA Wells Operations Notification System (WONS) database​
  • All existing E&A and open water suspended wellbores

Objectives​

  • Ensure guidance is maintained for suspended wells and well decommissioning in reservoirs that have a potential or foreseeable future use: CCS suitable reservoirs
  • Support cross industry and agency engagement facilitating optimisation of well decommissioning activity on the UKCS​
    Assist in improving understanding of well removal environmental impact ​


Deliverables

  • Technology roadmap – OGTC, TLB, Norce​
  • Updated guidance for suspended wells and well decommissioning in reservoirs with future use ​
  • Supply Chain Strategy - focused on optimisation of well decommissioning activity ​
  • Environmental impact of well removal and decommissioned wellbores​
