EcoVapor Recovery Systems
July 2014
1

• Implemented earlier this year
• Focused on Methane emissions
– Methane is a greenhouse gas 21 times more potent than Carbon Dioxide
– When you burn Methane, Carbon Dioxide is a byproduct
• Also largely focused on leak detection and prevention
2

• Regulation 7 requires oil and gas operators to control methane emissions from oil storage tanks
• The regulation covers all wells making more than 10 BOPD (6 tpy emissions)
• Operators can choose to burn or recovery the gas that comes off the tanks

Post-Tank Vapor Emission Control
• Proven innovative emission control system converts tank emissions from waste/incineration to useable NG/NGLs
• A typical 8 well site in the DJ currently incinerates up to $500,000 per year
• 25 ERS units deployed in DJ since 2011
• Cumulative capacity 321,200,000 SCF per year
• Remove the VOC equivalents of 28,000 cars/year
• Heat over 9,000 homes per year
• DJ Opportunity: Billions of SCF per year

ERS Provides Economic, Safe, Environmentally
Friendly, and Reliable Vapor Recovery
• ERS Units are Economic
• By turning flared waste gas into a saleable product, ERS adds to the revenue of a production location
• With no Capital Expense, Operating Expense, or service costs, net profit is increased
• ERS increases the gas sales price by increasing BTU content with our special patent pending oxygen reduction technology that allows recovery of flash gas at acceptable pipeline levels (<2PPM)
• ERS Units are Safe
• Automated and remote monitored system with 30 safety shutdown triggers ensure the unit is safe
• Lower oil tank vapor pressure leads to a reduction in LEL hits and lower
VOC incinerator pressures allowing incinerators to operate in dormant mode and increasing site safetys

ERS Provides Economic, Safe, Environmentally
Friendly, and Reliable Vapor Recovery
• ERS Units are Environmentally Friendly
• 99+% emission control
• Reduces or eliminates regulatory risk of fines from flaming or smoky incinerators
• Small footprint does not complicate wellsite
• ERS Units are Reliable
• Robust design allows for operation at higher line pressures and higher
NGL levels with better liquids management than other VRUs
• No impact to well site operations during ERS unit downtime

ERS systems recover the richest gas on location
• ERS installs systems on location capable of recovering 30, 60, and 120 MCFD depending on the productivity of the site
• Last year’s installations yielded 3000 BTU gas on average
• ~$16.00 per MCF net (net of POP, royalty, severance tax, estimated recovery rates, monthly prices, averaged over 12 month well decline rate)
• Because we remove H2S and Oxygen, we are treated as a gathering or marketing deduct so there is no impact on LOE.
Note: We use actual Producer prices, production costs, gas composition samples and MCF gas captured to calculate values

ERS Vapor Management: Oxygen Removal
• Monitors O
2 concentration at system inlet and outlet.
• Pipelines allow 10 parts-per-million. Inlet concentrations above 5%
(50,000 ppm) O
2 are not uncommon.
• ERS technology actively removes oxygen molecules from tank vapor gas stream.
• Potential for >10 ppm when the unit is starting up, or restarting if the wells were off for a time period.
 System recirculates gas until O
2 concentrations are acceptable.
• Average oxygen at custody meter less than 2 ppm
