Centralizers

Oilfield Service Professionals has built a reputation of supplying high-quality steel and polymer centralizers. OSP offers a wide range of hinged and slip-on solutions, as well as, stop collars and other accessories. From tight-tolerances to severe doglegs and rough-cut windows, OSP is a phone call away.

​

​

OSP is also the preferred USA distributor of the Matrix range of patented low friction composite drilling and completions centralizers. The Max-R™ solution was engineered specifically for today’s extended reach operations. Max-R™ centralizers are designed to convey well screens, completion tool strings and typical casing and tubing strings into highly deviated and challenging horizontal wellbores. The 100% metal-free polymer Max-R™ centralizers are made from proprietary blends of premium engineering grade polymers. This makes them robust, durable and able to deliver superior performance to take your further, faster.
