  2. About us Gaspro Compression Corp. is the leading provider of low horsepower (below 100 HP) gas compressor packages in Canada. Our company was born and raised in Three Hills, Alberta — however in terms of industry positioning, we are anything but “small town.” Being able to adapt our technology to best fit clients’ needs, is one of the many reasons we have evolved into an industry leader. Since 2003, Gaspro has been developing dependable, low maintenance and user friendly compressor packages that surpass industry standards. All our packages are engineered for extended, cost efficient operation and we are continually improving and innovating our products to keep up with the ever changing industry demands

  3. Our applications include: Casing gas compression Gas well compression on oil wells Tank vapor recovery units (VRU) BTEX VRU on glycol dehydrators

  4. CASING GAS COMPRESSION

  5. How casing gas compression works Without a compressor With a compressor Oil Oil Gaspro package Casing gas Tubing Tubing Annulus between casing and Gaspro compressor package oil tubing fills up with reduces the pressure in the Casing Casing annulus, thus allowing more associated gas (often referred as “solution gas” or “casing reservoir products (oil, water, gas” ). If the pressure in the gas etc.) to flow into the well bore annulus gets too high, it holds P low P high back the flow of reservoir products into the well bore. Reservoir Reservoir Formation Formation Well bore Well bore

  10. SOLVENT VAPOR RECOVERY

  11. Some basic statistics – Feb 2017 Stats Total Alberta oil production: ~ 3.3 million bpd 1  About 1.3 million bpd of thermal bitumen production 2 (Most of which is  through SAGD) Solvent extraction technologies are being tested as alternative to SAGD.  Gas Pro has provided compressors for recovery of propane solvent and  butane solvent pilots. Performance variation can be quite large:  Blackmer NG602 Compressor – 30 psig suction, 200 psig discharge, 825 RPM, 13.5 psi atm, 86 F gas temperature at suction Butane Propane Natural Gas (0.65 SG) SCFM 56.6 87 106.2 BHP 12.5 17.6 22.2 Also need to consider liquids dropping out at high pressures  1. http://www.oilsandsmagazine.com/energy-statistics/alberta – February 2017 data – Accessed Nov. 9, 2017 2. http://www.albertacanada.com/files/albertacanada/AOSID_QuarterlyUpdate_Fall2017.pdf – February 2017 data – Accessed Nov. 9, 2017

  12. TANK VAPOR RECOVERY UNITS

  13. Crude oil storage tanks emit methane and other volatile organic compounds that flash off from the oil. Gaspro’s vapor recovery units (VRU) are designed to recover the vapors coming off from the tanks (typically at only a few ounces (oz/in2) of pressure) and then compressing it back into the system. The VRU can provide significant economic and environmental benefits to the client.

  14. BTEX RECOVERY UNITS

  15. Benzene is a carcinogenic compound whose emissions from glycol regenerator still columns at natural gas dehydrator facilities are strictly regulated in Alberta in accordance with Alberta Energy Regulator’s (AER) Directive 039. Gaspro Compression’s BTEX VRU system recovers all emissions from the regenerator still column and reinjects the recovered vapor into the facility

AER Directive 039 – Table 2* Implementation schedule by calendar year to reduced emissions 2014 2015 2016 2017 2018 Distance in metres (m) Emission limit required as of January 1 of the calendar year in tonnes (t) No control or ≤ 100 0.0 a control 101 – 250 0.1 other than an appropriately 251 – 750 1.0 0.5 designed flare or incinerator > 750 3.0 2.0 1.0 After control ≤ 250 1.0 emission limit for an 251 – 750 1.0 appropriately designed flare > 750 3.0 or incinerator * Source: AER Directive 039: Revised Program to Reduce Benzene Emissions from Glycol Dehydrators, January 22, 2013 - Accessed: 03/18/2016 – URL: https://www.aer.ca/documents/directives/Directive039.pdf
