HV/LV Poly Anionic Cellulose (PAC): High-Purity Drilling Mud Treatment Agent for Oilfield Applications

We offer HV/LV Poly Anionic Cellulose (PAC), a premium-grade drilling mud treatment agent engineered for superior fluid loss control and viscosity enhancement in oilfield and drilling applications. Available in both High Viscosity (HV) and Low Viscosity (LV) grades, our PAC delivers exceptional performance in water-based drilling fluids across onshore and offshore operations. With a purity of ≥95% and moisture content of ≤10%, this product meets the rigorous demands of modern drilling engineering.

HV PAC is designed for applications requiring high viscosity and superior fluid loss control. It significantly increases the rheological properties of drilling fluids, improving cuttings transport and hole cleaning efficiency. HV grade is particularly effective in vertical and low-angle well sections where hole stability and effective suspension of weighting materials are critical.

LV PAC provides excellent fluid loss control with minimal viscosity increase, making it ideal for high-density drilling fluids and operations where maintaining low rheological profiles is essential. It is widely used in deep wells, horizontal drilling, and high-temperature environments where excessive viscosity can cause equivalent circulating density (ECD) management challenges.

• Superior Fluid Loss Control: Effectively reduces filtrate loss into permeable formations, preventing formation damage, maintaining wellbore stability, and protecting reservoir productivity. Low filtrate volume ensures minimal invasion of drilling fluid into producing zones.
• Excellent Viscosity Enhancement: HV grade delivers apparent viscosity of ≥50 mPa·s, providing outstanding cuttings suspension, hole cleaning, and weighting material support in water-based mud systems.
• High Purity (≥95%): Manufactured with strict quality control to ensure minimal impurities, consistent performance, and reliable batch-to-batch reproducibility that drilling engineers can depend on.
• Temperature & Salt Tolerance: Maintains effective performance across a wide range of downhole temperatures and in the presence of formation brines, salts, and contaminants commonly encountered during drilling operations.
• Environmentally Compatible: Formulated to conform to standards for starch and cellulose derivatives, offering an environmentally responsible choice for drilling operations with strict environmental discharge requirements.
• Dual Grade Availability: HV and LV grades provide drilling engineers with the flexibility to optimize mud formulations for specific well conditions, formation types, and operational requirements.

PAC is a core additive in water-based drilling mud systems for both onshore and offshore oil and gas wells. It serves as the primary fluid loss control agent and viscosifier, ensuring wellbore stability, cuttings removal, and formation protection throughout the drilling process from spud to total depth.

In complex well trajectories, LV PAC provides essential fluid loss control without excessive viscosity buildup, helping to manage ECD and prevent lost circulation in extended-reach and horizontal sections where pressure management is critical.

Beyond oil and gas, PAC is effectively used in geothermal drilling, water well construction, and mineral exploration drilling where reliable fluid loss control and hole stability are required in varied geological formations.

PAC is also incorporated into workover and completion fluid formulations to provide temporary fluid loss control and viscosity during well intervention operations, protecting the reservoir from damage during maintenance and completion activities.

Every batch of our Poly Anionic Cellulose is manufactured under ISO-certified quality management systems with comprehensive testing for purity (≥95%), moisture content (≤10%), apparent viscosity (≥50 mPa·s), filtrate volume, and starch derivative compliance. Products are packaged in 25 kg multi-wall paper bags with moisture barrier liners or 1,000 kg supersacks, suitable for international shipping. Certificates of Analysis (COA) and Material Safety Data Sheets (MSDS) are provided with every shipment.

With high purity of ≥95%, dual HV/LV grade availability, consistent performance, and competitive pricing, our Poly Anionic Cellulose drilling mud treatment agent delivers the reliability and cost-effectiveness that drilling operations demand. We welcome inquiries from drilling fluid service companies, oilfield chemical distributors, and E&P operators worldwide seeking a trusted PAC supplier for their water-based mud programs.
