CERAMIC BEADS

DESCRIPTION: CERAMIC BEADS are excellent for horizontal and deviated well bores to reduce or eliminate torque and drag problems. They can also be used for running casing and liner to reduced drag created by closer tolerances and stiffer hook-up. CERAMIC BEADS are not adversely affected by pressure, temperature or mud chemistry and can be used in any type system with their superior strength and roundness . CERAMIC BEADS will not float out or migrate up the hole and are blended to achieve optimum particle size.
