Over 30 years building a reputation for quality

OSP works with the global oil and gas community to create solutions for the effects of water and its use. From consulting services to on-site and in-lab microbial testing services, to chemical supply, OSP is focused on water treatment solutions that protect assets. Driven by data, we help clients choose the right biocides for their unique applications. Our commitment to quality is evident in the technical support and customer service we provide.

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 across 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.
