Oil Well Drilling Glass Beads
Glass Beads can be used in all water and oil based drilling fluids to reduce torque and drag and to aid in the prevention of differential sticking. They should have no measurable effect on the desired properties of the mud system and can be removed by a desilter or centrifuge.
Adding and maintaining 8.0-12.0 kg/m³ of Glass Beads can achieve a reduction in torque and drag anywhere from 15.0 to 30.0%. The severity of hole problems and solids content will determine actual concentrations required.
