For professionals in the oil and gas industry, the precise selection of chemical additives is crucial for operational success. Sodium Carboxymethyl Cellulose (CMC) is a cornerstone ingredient in drilling fluids, prized for its viscosity-enhancing and fluid-loss control properties. However, with various grades and specifications available, understanding these details is key to making an informed purchase. This guide, provided by NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of oil drilling chemicals, aims to demystify CMC specifications for procurement managers and technical buyers.

Decoding CMC Specifications: What Buyers Need to Know

When sourcing CMC for oilfield applications, several key specifications will guide your decision:

  • Product Name and CAS Number: The primary chemical is Sodium Carboxymethyl Cellulose, with the CAS number 9004-32-4. This universal identifier ensures you are procuring the correct chemical compound.
  • Viscosity: This is arguably the most critical parameter for oil drilling CMC. Grades are typically categorized by their viscosity in a 1% or 2% aqueous solution. High-viscosity (HV) grades are generally preferred for drilling fluids requiring significant thickening and suspension capabilities, while low-viscosity (LV) grades might be used for specific applications where lower rheology is desired. Understanding your drilling fluid formulation's requirements will dictate the necessary viscosity.
  • Purity: For industrial applications like oil drilling, a purity level typically above 90% is common. Higher purity grades (often exceeding 99.5%) are reserved for food and pharmaceutical applications. As a trusted manufacturer, we ensure our oil drilling grade CMC meets the required industrial purity standards.
  • Degree of Substitution (DS): While less commonly a primary purchasing factor for oil drilling, the DS indicates the number of carboxymethyl groups attached to the cellulose chain, influencing solubility and properties.
  • Appearance and Physical Form: CMC is usually supplied as a white to off-white powder or granules. Particle size can also be a consideration for dissolution rates.
