MAIDE Ceramics Company has worked to develop high crush proppants.

MAIDE Ceramics Company has worked for several years to develop improved, high crush proppants. A wide variety of materials weretested in the laboratory under simulated reservoir conditions. One material,sintered bauxite proppant particles, showed greatly improved properties particles,showed greatly improved properties over any material available in the past andit has been field tested to date in 12 wells--all deeper than 10,000 ft.
