At Mostar, we’ve been designing and manufacturing top-quality downhole tools in Canada since 1975. By the late 1990s, some of the leading directional companies in North America relied on Mostar for mud motors, gap subs and transmitter. We have brought our reputation and experience creating innovative technology for our customers to what is now a full-service creator and supplier of telemetry and other downhole solutions
