High strength for deep and hostile downhole environments
CARBOHSP® is the original high-density sintered bauxite proppant, with enhanced performance to maintain high fracture conductivity in deep hot, high-stress downhole environments.


  • High strength and conductivity for use in deepest wells
  • Excellent roundness and sphericity
  • Available in five sizes—12/18, 16/30, 20/40, 30/60, and 40/70


  • Maintains high fracture conductivity in deep, high-temperature and similarly harsh downhole environments
  • Minimizes abrasion characteristics that cause wear on production and pumping equipment
