Engineering Services Calgary

Gas Liquids Engineering Ltd. (GLE) is a privately owned engineering firm providing engineering services from our Calgary, Alberta offices since 1987. Occupying over 85000 square feet in our two corporate buildings, GLE is comprised of over 225 engineers, designers, consultants, and administrators serving both the Canadian and International EPCM (Engineering, Procurement, and Construction Management) markets.

In addition to general oil and gas project engineering services and management services, GLE has recognized niche strengths in refrigeration, gas processing, power generation, liquids fractionation, amine sweetening and acid gas injection. We provide highly flexible engineering services that are truly customized to meet the specific needs of each client.

GLE’s founders include Doug MacKenzie, Jim Maddocks, and Arnie Toews, who started the company in 1987. At that time, the three of them already averaged more than a decade of experience in oil and gas and industrial construction, equipment design, drafting, shop fabrication and field construction. They had already built facilities and published technical papers on MDEA sweetening and the use of mixed refrigerants in gas plant liquids production (see our Publications page). Their experience included some of the very first designs and uses of modularized process packages to reduce site-built construction costs, including packaged refrigeration and amine plants. Many of these facilities are still in use today, 33 years later, with the designs often referenced as standard industry designs. On this foundation of corporate knowledge, GLE has steadily grown and provided engineering services on hundreds of gas and liquids processing facilities ranging from the very small, up to 1 BCFD and 74,000 bbl/day. We are proud of our heritage in the industry as Canada’s most experienced privately-owned gas and liquids facilities engineering services provider, and we are also proud to offer our specialty engineering services both locally and internationally.
