What Gas Liquids Engineering does

Gas Liquids Engineering Ltd. (GLE) is a privately held, Calgary-based EPCM (Engineering, Procurement, and Construction Management) services firm founded in 1987 by Doug MacKenzie, Jim Maddocks, and Arnie Toews. The company provides oil and gas facility engineering services spanning project management, process engineering, mechanical, civil, electrical, EIC, automation, and regulatory/environmental disciplines, with 225 engineers, designers, consultants, and administrators (averaging 18 years of industry experience). GLE serves clients ranging from small one-well independent producers to large multinational oil and gas companies, with delineated practice areas in gas processing, oil/condensate facilities, CO2 processing and sequestration, geostorage/acid gas injection, power generation, liquids fractionation, terminals, and adjacent hydrogen and biofuels facilities.

GLE's competitive position is anchored by proprietary process technologies (DexPro™ for CO2 dehydration, SABR Deep Cut for gas processing, SaltPro SXT™ for salt cavern storage) and proprietary calculation software (AQUAlibrium for acid gas/water equilibrium, GLEWPro for injection pressure estimation). The firm has completed over 8,000 projects across 800+ clients, including 40+ CO2/H2S sequestration projects and 250+ international oil and gas processing unit operations across 25+ countries. Director Ian McKay holds 36 patents and Director John Carroll has authored 50 technical papers and 8 books on acid gas injection, establishing GLE as a recognized global authority in CO2/H2S handling.

GLE generates revenue through project-based professional services fees on EPCM engagements, with individual projects exceeding $500M in capital value and the firm managing over $1.2B in capital projects simultaneously. Distribution is driven by senior leadership (CEO Stuart MacKenzie, VP Projects & Business Development Ryan Arnold, VP Global Projects Aubrey Dekok) engaging in direct enterprise sales, supplemented by technical publications, the Acid Gas Injection Symposium (co-sponsored with Sphere Technology Connection), and a LinkedIn presence. The company maintains COR certification, ISNetworld/Complyworks/Avetta qualifications, and engineering authorizations across 11 jurisdictions, including recently completed work on the Ridley Island Energy Export Facility. Revenue is not publicly disclosed.

Directly comparable to GLE in services delivered, customer base (O&G producers, midstream operators), and project model; materially larger in headcount and geographic spread but operates in many of the same asset classes.
• Bantrel Co. Calgary-headquartered EPCM firm serving Western Canadian oil sands, gas processing, and midstream projects. Shares GLE's Alberta/Canadian customer base, EPCM service offering, and gas-plant facilities focus; competes for similar process-engineering and project management mandates in Western Canada.

Broad incumbents

• Fluor Corporation: U.S.-based global Tier-1 EPCM firm with capabilities in upstream, midstream, LNG, refining, petrochemicals, mining, and government services. Direct capability overlap with GLE on O&G EPCM but operates at materially larger scale and with a much more diversified portfolio.
• AtkinsRéalis: Canadian-headquartered engineering and project management firm (formerly SNC-Lavalin) serving oil & gas, nuclear, infrastructure, and renewables. Competes with GLE on O&G and midstream EPCM in Canada but its portfolio is significantly broader across infrastructure and nuclear.
• Stantec: Canadian-headquartered global engineering, architecture, and consulting firm serving energy, infrastructure, water, and environmental markets. Overlaps with GLE on Canadian O&G and midstream engineering work but services a much broader set of end markets.

Regional players

• Graham Construction: Western Canadian construction and EPCM firm with energy, industrial, and civil infrastructure divisions. Competes with GLE for industrial/energy project mandates in Alberta and BC; closer to construction-led delivery than pure engineering but overlaps on regional oil & gas facility projects.
