Product Description

Ground Marble/CaCO3 Bridging Agent: Acid-Soluble, Multi-Grade Filler for Optimized Fluid Loss Control, Wellbore Stability & Reservoir Drilling in Oil & Gas Operations

Ground Marble (All Grades) is a lost circulation material available in three grades: DC-FINE (0.1-5μm), DC-MEDIUM (5-15μm), and DC-COARSE (15-25μm). Its bulk densities are 0.8-1.0 g/cm³, 1.0-1.2 g/cm³, and 1.2-1.4 g/cm³ respectively, with acid solubility over 95% (in 10% HCl) for all grades. Physical properties include color ranging from white to off-white, particle size from 5 microns to 200 mesh, bulk density of approximately 1.2-1.5 g/cm³, specific gravity of 2.7-2.9, and moisture content below 0.5%. Chemically, it is dominated by calcium carbonate (content ≥98%) with low impurities: silica (<0.5%) and iron oxide (<0.1% respectively), making it suitable for lost circulation control in drilling fluids.

Other Uses:‌ Includes adhesives, sealants, rubber products, and environmental remediation (e.g., acid neutralization).
 
3,Handling and Storage Guidelines
Store in a dry, cool, and well-ventilated area to prevent moisture absorption and caking.
Use appropriate personal protective equipment (PPE), including dust masks and goggles, during handling to minimize inhalation risks.
Avoid contact with acids, as they may cause effervescence and degradation.
