Profile: Cabot Specialty Fluids produces cesium formate brine and powder products for the oil & gas industry. Our products include cesium & potassium formate brine and cesium formate powder. Cesium formate brine is a high density clear fluid used for well control in HPHT well construction operations. Formate brines are suited for HPHT drilling, completion, work over and fraccing operations. It minimizes formation damage and avoids screen plugging & reduces risk & uncertainty. Cesium formate powder is used to weight up high-density cesium formate brine and cesium/potassium formate brine blends during field use. We use potassium formate brine for blending with cesium formate brine to create low-solids fluids. We also offer drilling, completion and intervention fluids that are used for HPHT applications.
