CARBO Ceramics Inc., an oilfield services technology company, manufactures and sells ceramic proppants, resin-coated ceramic, and resin-coated sand proppants for use in the hydraulic fracturing of natural gas and oil wells in the United States and internationally. The company offers ceramic proppants, including CARBOHSP and CARBOPROP designed for use in deep oil and gas wells; CARBOLITE used in medium depth oil and gas wells; CARBOECONOPROP, a low-density ceramic proppant; CARBOHYDROPROP to enhance performance in slickwater fracture treatments; and CARBOBOND LITE, a resin-coated ceramic for oil and natural gas wells that are subject to the risk of proppant flow-back. Its ceramic proppants also comprise CARBO NORTHERN WHITE, a frac sand that is used by operators that value quality; CARBONRT, a detectable proppant used to assist operators in determining the locations of fractures in natural gas and oil wells; KRYPTOSPHERE HD, a ceramic proppant engineered to deliver increased conductivity and durability in the highest closure stress wells; and SCALEGUARD, a porous ceramic proppant that is infused with scale-inhibiting chemicals and placed throughout the fracture as part of the hydraulic fracturing process.
