Throw the best wrench at it ®



Executive Team

HUWE®’s senior management comprises oilfield veterans with decades of experience at the well site and in the fabrication shop. We know our materials, we know how to build things that work and last, we understand the needs of field crews from our own bottom-up experience. And we love to invent things – tools and parts that work better and make life on the job site safer and more convenient. That’s the HUWE® team.

Marc Dumaine


Marc’s over 30-year-long career spans oil and natural gas well drilling, production well testing, under-balanced drilling, designing and manufacturing a wide variety of oilfield equipment, and the founding and management of several companies. He is the co-inventor and developer of the HUWE® and a partner in HUWE® Inc.

Marc was born and raised on a farm near Storthoaks, Saskatchewan, in the historical oil country of the province’s southeast. He began working on drilling rigs in Saskatchewan in 1983. In 1990 he joined Norward Energy in Calgary, Alberta, doing production testing, and after a number of years joined another company to work in under-balanced drilling, where he also gained experience in sales.

In 2001 Marc founded Magna Flo Systems. Magna Flo designed and manufactured full under-balanced drilling systems, including separation and nitrogen packages, for use in Russia. The company also helped build coiled tubing rigs. In 2008 Marc launched Magna Fab Inc. It has facilities in Saskatchewan focused on the welding and manufacturing of oilfield equipment, including pipe tubs, Texas gates, mud tanks, and various drilling rig components, as well as hard-banding of drill pipe, non-mag collars and repair of farm equipment. Magna Fab Inc. also has a welding shop in Calgary which is focused on “B” pressure welding and is ASME-certified.

In addition to his enduring interest in designing things, Marc’s hobbies are fishing, camping, relaxing at his cabin in British Columbia and auctioneering at fundraisers.
