    Cal Carb Supercal – Glass Rock

    Cal Carb Supercal – Glass Rock is a medium grind carbonate with a particle size larger than Cal Carb 0 or Cal Carb 325 grind, but less than Cal Carb Poultry Grit.

    It can be used in combination with other sized carbonates to provide a wide spectrum of bridging agents for drilling fluids. Its acid solubility also makes it especially suitable as a weighting or bridging agent in completion/work over and stimulation operations.

    • Prevent fluid invasion of permeable zones
    • Prevent loss of circulation during drilling, workover and completion activities
