Victor Petrovic, President

“We do things differently than other companies – and all with that personal touch.”

A machinist by trade, Victor started his own business, Victor’s Machine Works (VMW), in 1975. From its humble beginnings as a small shop, Victor’s business had only a few small machines to its name. Initially, Victor established market share by manufacturing and repairing oilfield parts and equipment. Within three years, he was building drilling rigs. VMW soon flourished, becoming one of the most well known machine shops in Canada. Clientele later expanded into the U.S.A. and around the world.

Victor has catered to the oil and gas industry for more than 30 years, specializing in manufacturing and repair work for a wide range of drilling service companies. With various directional companies as his clients, Victor gained real expertise in manufacturing and servicing directional tools and equipment. Earning a solid reputation for quality and precision work, he naturally built long-term relationships with many of them. As the business grew, he remained dedicated to providing his clients with personalized service. True pride of ownership is still evident in his work today.

Victor invests the same amount of drive and energy in his personal interests as he does in his business. He competes regularly in the Boston Marathon and has been a 2nd degree black belt in Kung Fu for more than 25 years.

On the beginning of Mostar, Victor commented, “We have the experience, the people and the resources to make it work. We want to offer directional drilling services and advantages that no other company can match.”

John Petrovic, Vice President

“I just see better ways to get the job done.”

John started Foothills Millwright Service in 1991. He specialized in mill work and shut downs for a variety of plants in Calgary. For nearly ten years, John has also worked in partnership with Victor, becoming increasingly involved in the operation of Victor’s Machine Works (VMW).

Mentored by Victor, John worked hard to establish significant market share and earn a reputation for consistently exceeding customers’ expectations. Together, they’ve become true partners in foresight. When asked about the creation of Mostar, John adds, “Our focus, our vision, is always the same. The beginning of Mostar was just the next step for us - a natural evolution in our business.”

John completed his Mechanical Engineering degree from the University of Calgary in 2000 while continuing to operate VMW and Foothills simultaneously. With genuine passion for mechanical engineering and design, John uses innovative ideas to create new technology. Over the years, he’s made significant improvements in equipment design, form and function for multiple clients.  Together, he and Victor have designed three successful mud motors for the directional drilling industry.

John is always looking to incorporate new strategies and ideas into business operations, positioning Mostar for continued success in the future. “We wanted to do directional the way we feel it should be done.”

We don't rely on third party definitions of good maintenance. We do it all in-house.
