CARBOHSP high-density sintered bauxite proppant

CARBOHSP bauxite proppant is the original sintered bauxite ceramic proppant. Engineered to offer exceptional strength for use in the deepest wells, it maintains high fracture conductivity in hot, hostile downhole environments.

Its excellent roundness and sphericity minimize the abrasion characteristics that cause wear on production and pumping equipment.

Available in four sizes—12/18, 16/30, 20/40 and 30/60.
