Carbo Ceramics Inc is an oil and gas equipment and services company. The company offers production-enhancement products and services to exploration and production companies, helping them increase production rates and recoverable amounts of hydrocarbons from their wells. Its customers typically are well operators or oilfield service companies whose operations focus on the hydraulic fracturing of oil wells. The company’s core operations lie within the production and sale of proppants, which are materials pumped into fractures in wells to “prop” them open, allowing hydrocarbons to flow from the well easier. The majority of Carbo Ceramics’s revenue is generated within the United States, with a smaller portion coming from Canadian and other international markets.
