Calcium Carbonate
Catalog NO.: AIMRSE-CHM-ADD-179 Manufacturer PN: CHM-CAC-CAR
• Highly acid-soluble product; extremely low settling risk; when using limestone powder as a weighting agent, finer shaker screens can be used to reduce fluid loss risk, allowing for higher mechanical drilling speeds.
Increase completion fluid density up to 1.68 to prevent permeable formations from formation water intrusion, reducing loss risks during drilling, completion, and workover operations; commonly used in reservoir drilling fluids.
This product is a micron-grade calcium carbonate weighting agent produced through specialized processing techniques. It is used to increase the density of low-density drilling and completion fluids up to 1.68 sg. It is commonly used in oil-based drilling fluids, workover fluids, completion fluids, and reservoir-specific drilling fluids. Its acid solubility rate in hydrochloric acid approaches 98%, which reduces reservoir blocking and improves oil and gas recovery rates.
