3 General Flaring Practices Well Test FlaringWell Test Flaring  short term (typically a few days)  potentially large volumes Solution Gas Flaring (Routine)Solution Gas Flaring (Routine)  continuous  low volumes Emergency/Upset FlaringEmergency/Upset Flaring  short duration (typically a few hours)  low volumes Non-Routine FlaringNon-Routine Flaring  short term (typically a few days to weeks)  potentially large volumes  High GOR wells shut-in

4 Flaring Breakdown for 2001

5 Historical Flaring Perspective in B.C. Significant flare reductions despite having a formal reduction policy (1997 to 2001  48%)Significant flare reductions despite having a formal reduction policy (1997 to 2001  48%) Informal policy consisted of:Informal policy consisted of:  review and approve all well test flare volumes  review flaring at non-conserving batteries periodically  review and approve all planned facility flaring with high GOR wells shut-in Early reductions a result of infrastructure development in Buick and W. StoddartEarly reductions a result of infrastructure development in Buick and W. Stoddart

6 BC Historical Flaring Data by Type ( ) (Cross-hatched areas represent estimated unmeasured/unreported emissions )

7 Flare Reduction Drivers Public health and safetyPublic health and safety Resource conservationResource conservation GHG ReductionsGHG Reductions AEUB Guide 60AEUB Guide 60  Excellent example of a multi- stakeholder approach to problem solving  Alberta success drove B.C. initiative

8 Flare Reduction Challenges TechnologyTechnology Regulatory flexibilityRegulatory flexibility  Electricity generation  Royalty exemptions Promote corporate cooperationPromote corporate cooperation

9 Flare Reduction Project Operations engineering has worked on this project for over two yearsOperations engineering has worked on this project for over two years Evaluated flaring data (where, why and how much)Evaluated flaring data (where, why and how much) Reviewed Guide 60 and monitored success in AlbertaReviewed Guide 60 and monitored success in Alberta Liased with operators and other ministriesLiased with operators and other ministries

10 BC Proposed Flare Reduction Targets 1997 chosen as baseline1997 chosen as baseline Proposed TargetsProposed Targets  50% below 1997 baseline volume by the end of 2004  55% below 1997 baseline volume by the end of 2005 Seek industry and stakeholder inputSeek industry and stakeholder input Must address data reporting deficienciesMust address data reporting deficiencies

11 BC Historical Flaring Data by Type ( ) with Proposed Reduction Targets (Cross-hatched areas represent estimated unmeasured/unreported emissions )

12 Flare Reduction Strategies Utilization of AEUB flare management hierarchyUtilization of AEUB flare management hierarchy  Eliminate  Reduce  Improve efficiency Economic assessment of conservation of all solution gas flaresEconomic assessment of conservation of all solution gas flares

13 Strategies Continued Limiting non-routine flaring during facility outagesLimiting non-routine flaring during facility outages  Reduce inlet gas volumes (up to 75%) based on duration and type of shutdown Seek stakeholder inputSeek stakeholder input  CASA, OGPAG, or others  Take advantage of momentum in Alberta

14 Summary OGC is committed to flare reductionsOGC is committed to flare reductions Implement four strategies initiallyImplement four strategies initially A unified approach across provincial boundaries is preferredA unified approach across provincial boundaries is preferred

15 Summary Continued Province of BC is committed to a ‘Results Based’ regulatory systemProvince of BC is committed to a ‘Results Based’ regulatory system  Minimize red-tape  Reduce regulatory burden Flaring reductions since 1997 an excellent example of industry/gov’t cooperationFlaring reductions since 1997 an excellent example of industry/gov’t cooperation
