Carbo Ceramics Inc is a Delaware corporation was incorporated in 1987. The Company is a supplier of ceramic proppant and provides fracture simulation software, fracture design, engineering and consulting services and a broad range of technologies for spill prevention, containment and countermeasures. The Company sells the majority of its products and services to operators of oil and natural gas wells and to oilfield service companies to help increase the production rates and the amount of oil and natural gas ultimately recoverable from these wells. Its products and services are used in the hydraulic fracturing of natural gas and oil wells. The Company manufactures five distinct ceramic proppants. CARBOHSP(r) and CARBOPROP(r) are high strength proppants designed mainly for use in deep gas wells. CARBOHSP(r) has the highest strength of any of the ceramic proppants manufactured by the Company and is used mainly in the fracturing of deep gas wells. CARBOPROP(r) is slightly lower in weight and strength than CARBOHSP(r) and was developed for use in deep gas wells that do not require the strength of CARBOHSP(r). CARBOLITE(r) and CARBOECONOPROP(r) are lightweight ceramic proppants designed for use in natural gas wells of moderate depth and oil wells. CARBOLITE(r) is used in medium depth oil and gas wells, where the additional strength of ceramic proppant might not be essential, but where higher production rates could be achieved due to the products uniform size and spherical shape. CARBOLITE(r) is commonly used in oil wells. CARBOECONOPROP(r), introduced in1992 to compete directly with sand-based proppant, and CARBOHYDROPROPtm, introduced in late 2007 to improve performance in slickwater fracture treatments, is the Company's lowest priced products. It competes with Saint-Gobain Proppants. Ceramic proppant is made from alumina-bearing ores commonly referred to as clay, bauxite, bauxitic clay or kaolin, depending on the alumina content that are readily available on the world market. The Company owns multiple patents in the United States and various foreign countries that relate to different types of ceramic proppant and production methods used for ceramic proppant and media. The Company's operations are in substantial compliance with applicable domestic and foreign federal, state and local environmental and safety laws and regulations.
