Baker Hughes

Calgary, AB, CAN

From Calgary, Baker Hughes supports Western Canadian wells with wellheads, connectors, and intervention work from construction through abandonment. We bring the right equipment for jobs where access, connection, and repair have to stay controlled. Pipeline management and gas processing/LNG cover the path from well to plant and terminal. Downstream chemical work supports treatment, while terminal, blending, and transportation services keep product moving through the next handoff. Cordant digital solutions and iCenter maintenance services connect condition data with planning. Distributed vibration monitoring and machine protection give rotating assets a clearer operating picture. Pressure sensors add another layer of visibility, and our centrifugal pumps are built for harsh-duty service.

Northstar Drillstem Testers Inc

Calgary, AB, CAN

Reservoir decisions need downhole data that can be read and acted on while the well program is still moving. Northstar Drillstem Testers Inc delivers drill stem testing and well intervention services from Calgary, including closed chamber testing and wireless surface readout for oil and gas wells. Closed chamber testing gives a zero-emission, zero-flaring downhole well testing option. NorthstarLive! wireless surface readout brings live data, a downhole specialist, and live analysis into time-sensitive well decisions. We design most of our products through Canadian Professional Engineers and manufacture them in Canada. Each dimension is quality controlled in-house before assembly and acceptance testing in our deep well simulator. Our completion tools, packers, and drill stem testing systems are built for reservoir evaluation, well intervention, and pressure-related downhole work. From Calgary, we focus on test design, tool quality, and field data that support the next well decision.
