Product Description

Oil Drilling Grade CMC (Carboxymethyl Cellulose) Product Description

Product Name: Oil Drilling Grade CMC (Carboxymethyl Cellulose)
CAS No.: 9004-32-4
Molecular Formula: C8H15NaO8
Appearance: White or off-white powder
Solubility: Soluble in water, forming a stable and viscous solution

Product Overview

Oil Drilling Grade Carboxymethyl Cellulose (CMC) is a high-performance additive widely used in drilling fluids, completion fluids, and cementing systems. As a critical component in oilfield applications, CMC enhances viscosity, improves fluid loss control, and stabilizes wellbore conditions. Its excellent rheological properties help maintain drilling efficiency, reduce operational risks, and improve the overall performance of drilling mud.

Key Properties and Benefits

• Effective Fluid Loss Control - Prevents excessive water loss in drilling mud, maintaining wellbore stability.
• Viscosity Regulation - Enhances the carrying capacity of drilling fluids, improving cuttings removal.
• Wellbore Stability - Reduces formation damage and prevents collapse in unstable formations.
• High Salt & Temperature Resistance - Performs well in saline environments and under extreme temperatures.
• Eco-Friendly & Non-Toxic - Safe for use in oilfield operations with minimal environmental impact.

Applications

1. Drilling Fluids: Controls viscosity and fluid loss in both fresh and saltwater-based muds.
2. Completion Fluids: Ensures wellbore stability and prevents reservoir contamination.
3. Cementing Slurries: Improves fluidity and prevents water loss during well cementing.
4. Workover Fluids: Enhances the efficiency of well maintenance and production operations.
