Frequently Asked Questions
How should Graymont calcium carbonate products be added to drilling fluid?
Cal Carb 0, Cal Carb 325, Cal Carb Supercal – Glass Rock, and Cal Carb Poultry Grit can be added directly at the suction with agitation or through the mud hopper. To prevent settling in surface tanks, it is important to raise the fluid viscosity to ensure proper suspension. For safety, it is recommended to wear a dust mask and eye protection when mixing all powdered products.
How does the particle size of pulverized limestone affect its performance in drilling fluids?
The particle size of pulverized limestone plays a crucial role in its performance in drilling fluids. Finer grades, such as Cal Carb 0 and Cal Carb 325, are effective as weighting agents and for acid-soluble bridging in pressured zones. Coarser grades, such as Cal Carb Poultry Grit, provide better lost circulation control and bridging in larger fractures.
