Fractionated acid-soluble micromarble. A weighting agent and a colmatant for treatment of drilling muds, initial penetration drilling muds and well-completion and workover fluids.
Range of applications
The reagent is used as a weighting agent and a colmatant. The application of fractionated calcium carbonate optimizes granularity of drilling mud solids according to actual characteristics of a productive stratum or circulation loss interval. It is available in three basic grinding grades - FINE, MEDIUM and COARSE. To ensure high-quality development of a filter cake, it is recommended to maintain minimum reagent concentration of 3% by volume (80 kg/m3) and more.
