OGA Decommissioning Our team s mission To steer the UKCS overall decommissioning cost to 39bn* or less * 2016 money How? Engage early on decommissioning plans with operators Publicise benchmarks using OGA Stewardship Survey data Identify cost reduction opportunities/ challenges for decommissioning Promote collaboration across industry Identify and share lessons learned Support supply chain to develop capacity and efficiency Ensure MER UK behaviour implemented Asset Stewardship Expectations
Strategy and Programme Cost certainty and reduction Driving targeted cost efficiency programmes including innovative and regional approaches with extensive and effective knowledge sharing and best practice adoption Delivery capability Developing an efficient and exportable low cost and profitable delivery capability supported by a competent and efficient supply chain, a selection of business execution models all designed to allocate risk, align industry participants and drive down costs Scope, guidance and stakeholder engagement Working with BEIS and other relevant parties to identify and evaluate opportunities to further optimise and define parameters for decommissioning scope and improve industry engagement Builds on the Strategy Focus over the next year Sets out a number of key deliverables Clear action plan and timetable for delivery Reviewed on an annual basis

Need for Change Cost P90 P90 Probability P10 P50 Business as usual Probability P10 P50 Transformational approach Cost Industry and government have shared desire to minimise cost Awareness that business as usual will not be sufficient to transform cost Typical improvements of 35% seen in other industries e.g. automotive and aviation

How to measure success to deliver the target? 1.Change in total cost forecast vs previous year from Asset Stewardship Survey 2.Change in key cost area benchmark (P50) after each Stewardship Survey with new actual data 3.Improved cost definition for first 5 and 10 year forecast 4.Actual industry success stories indicating realised savings
OGA s key deliverables in 2018 1.Publish 2018 Decommissioning Cost Report 2.Publish Decommissioning Lessons learnt report 3.Complete Tier reviews with top 10 operators (based on total spent forecast over next 5 years) 4.Issue update for Decommissioning Delivery Plan
Decommissioning Task Force Objective: Minimise the cost of decommissioning in an appropriate manner, with a focus on delivering what would otherwise not be delivered by industry Team: Terri King (ConocoPhillips) Nigel Lees (Wood/Decom NS) Roy Aspden (CNRI) Pauline Innes (BEIS) Nils Cohrs (OGA) Win Thornton (BP) Mike Tholen (O&GUK)
