Company History

OSP was founded in 1988 by Calgary-based entrepreneur Michael McLennan, who saw a need for improved microbial control in the oil and gas industry. In 2011, OSP acquired US-based Telomer Corporation, a premier distributor of intermediates for water treating chemicals including scale and corrosion inhibitors, iron dispersants and biocides. In 2014, OSP Microcheck and Telomer Corporation were rebranded as OSP to reflect our commitment to provide proven chemical solutions to our clients in North America.

Operating in Calgary and Houston, OSP’s high-level technical expertise provides customers with unparalleled access to application experience, support and product recommendations for microbial identification and control, and scale inhibition across North America.

I wanted to take a moment to say thank you so much for our partnership. I cannot ask for a better partnership than the one I have with OSP. The dedication, time and effort to help us get up and going with ATP testing is something that has not gone unrecognized.
