Regulatory Update – Flare Options and Performance

2015 Bakken Oil Show – April 15-16, 2015 – Dickinson, ND

Flare System Applications

• Well site for NSPS Quad O compliance
• Central wellpad gathering facility for safely flaring of vents, air-assist flares
• Gas processing plants for safely flaring of relief vents, multipoint flares
• Flare monitoring advancements
• Causes for low Destruction Removal Efficiency (DRE)

Well Site Flare Options –
Open Flame

• Engineered flare system design
• High pressure vents off separator
• Low pressure vents off the tanks
• Combination flare for both streams
• Multiple Flares for scalability

Well Site Flare Options –
Enclosed Flame

• High pressure vents off separator
• Low pressure vents off the tanks
• Combination flare for both streams
• Properly designed, engineered enclosed flare will provide for greater than 98% VOC reduction

Conclusions

• NSPS Quad O compliance flares with 98%+ DRE
• Central wellpad gathering facility for safely flaring of vents, air-assist flares with 98%+ DRE
• Gas processing plants for safely flaring of relief vents, multipoint flares with 99.5%+DRE
• Causes for low Destruction Removal Efficiency (DRE)
  • Pilots per API 537 design and tested
  • Engineered flare systems, right MOC…
  • Technical resources and field support
