For multiple generations, the Johnson and Lindley families have been associated with oilfield chemistry. Their ownership of Magcobar (now M-I Drilling Fluids, a Schlumberger company), Champion Technologies (now Nalco Champion, an Ecolab company), and Athlon Solutions (now a Halliburton company) is a legacy of advanced knowledge of oilfield chemistry and top-quality service to the industry. J&L Laboratories continues that legacy by providing top notch independent laboratory services to the oilfield.
