Northstar’s downhole products are designed and tested to the highest standards and proven in the harshest environments. Northstar’s team of Canadian Professional Engineers (APEGA P.Eng) design most of our products, which are manufactured to precision in Canada. Every dimension is quality controlled in-house prior to assembly and acceptance testing in our deep well simulator. We retain full traceability from sourcing premium raw material until delivery and beyond, with future, compatible upgrades offered to all past customers. You get the downhole products our specialists operate around the world in the most demanding wells. Proven downhole technology straight to you.
