More than a decade ago, Cabot broke with traditional oil field chemical sales models by pioneering the leasing of its cesium formate drilling and completion fluids. With this model, Cabot retains ownership and stewardship of the chemicals at all times and charges customers for the number of days they are used in the field. At the end of the project, the fluids are returned for reclamation and leased out for the next job.

Jim Turner, Vice President of Operations for Cabot Specialty Fluids, said, "As long-time champions of the chemical leasing model in the oil segment, we are delighted to receive the UNIDO Chemical Leasing Award. Cabot has leased cesium formate brine to more than 250 well construction operations globally and with careful management we typically re-use 80 to 85 percent of the fluid. The leasing model benefits the environment by conserving chemicals and reducing water and energy use and is a sustainable business approach, helping to extend the overall life of our finite mineral resource."
