Proppants are one of the bright for calcined bauxite. These small ceramic beads, about the size of a grain, are pumped into hydrocarbon-bearing rock formations to prop open the fractures and stimulate oil or gas production. Bauxite-based high strength proppants are required in deep, high temperature and pressure hydrocarbon wells, which are often gas-bearing. Gas drilling is the biggest consumer of proppants and particularly those based on bauxite, since the formations tend to be deeper, but oil fields are generating new demand. Proppants will stimulate wellls and hold open fisuures and though most oil wells will produce naturally, they will produce faster if stimulated.
