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
