Polyanionic Cellulose (PAC) for Oilfield Drilling

Polyanionic Cellulose | High-Performance Drilling Fluid Additive | Improve Drilling Efficiency & Safety

Drilling Grade Xanthan Gum for Oil Drilling Fluid
High viscosity drilling grade xanthan gum used as rheology modifier and fluid loss control agent in oil and gas drilling fluids.

Polyanionic Cellulose (PAC) CAS No.  is a high-quality, water-soluble cellulose derivative, specifically designed for use in drilling fluids in the oil and gas industry. PAC helps improve drilling efficiency by enhancing fluid properties, reducing friction, and ensuring wellbore stability, even in the most challenging drilling environments. As a leading producer and exporter of chemical materials, InnoNew Material offers PAC that meets the strictest standards for performance and environmental safety.

Key Features & Benefits

  • Enhanced Fluid Viscosity: Improves the stability and performance of drilling fluids, ensuring consistent operation.
  • Friction Reduction: Helps reduce drill bit wear and torque, leading to increased drilling speed and lower operational costs.
  • Water-Soluble & Environmentally Friendly: Easy to mix with water and complies with international environmental standards for safe disposal.
  • High Thermal Stability: Ideal for high-temperature and high-pressure conditions commonly found in deep-well drilling.
  • Cost-Effective: Helps reduce overall drilling fluid costs by enhancing fluid longevity and performance.

Applications in Oilfield Drilling

Polyanionic Cellulose (PAC) is primarily used in the following applications within the oil and gas sector:

  • Drilling Fluids: PAC is a crucial component in water-based drilling fluids, providing high viscosity and stability in demanding drilling conditions.
  • Wellbore Stabilization: PAC helps prevent wellbore collapse by increasing fluid density and enhancing lubrication properties.
  • Lubrication in Drilling Operations: Reduces friction between the drill bit and formation, improving efficiency and extending equipment lifespan.
  • Water-Based Mud Systems: PAC is commonly used in water-based mud (WBM) systems to control rheology and reduce the need for toxic additives.

FAQ 

Q1: How does PAC improve drilling fluid performance?
A1: PAC enhances the rheological properties of drilling fluids, increasing their viscosity and stabilizing the fluid’s properties under high temperature and pressure, improving both efficiency and safety.

Q2: Is PAC safe for the environment?
A2: Yes, PAC is biodegradable and complies with global environmental standards, making it a safe and eco-friendly option for oil and gas drilling operations.

Q3: Can PAC be used in both freshwater and seawater-based drilling fluids?
A3: Yes, PAC can be effectively used in both freshwater and seawater-based drilling fluids, offering versatility for different drilling environments.

Q4: What is the difference between PAC-HV and PAC-LV?
A: PAC-HV (High Viscosity): Primarily a viscosifier with secondary fluid loss control. Used for hole cleaning and suspending cuttings.

PAC-LV (Low Viscosity): Specialized fluid loss controller with minimal viscosity impact. Ideal for high-density mud systems.

Q5: Is PAC compatible with other drilling fluid additives?

A: Yes. PAC is highly compatible with:
  • Salts (NaCl, KCl, CaCl₂)
  • Weighting agents (barite, hematite)
  • Other polymers (Starch, HEC, Xanthan gum)
  • Lubricants, shale inhibitors, and defoamers
