High Viscosity Polyanionic Cellulose PAC Polymer: Resolving Oil Drilling Fluid Instability Challenges

Oil drilling operations frequently face critical challenges with fluid loss control and viscosity stability under downhole conditions. Fluctuations in drilling fluid performance can lead to increased operational costs, wellbore instability, and delayed project timelines. Over our 10+ years serving the oilfield chemical sector, we’ve witnessed how substandard Polyanionic Cellulose (PAC) products compromise mud system integrity—especially in high-pressure, high-temperature (HPHT) environments where consistent viscosity and fluid loss control are non-negotiable.

A Reliable Solution for Drilling Fluid Formulation

Our High Viscosity Polyanionic Cellulose PAC Polymer addresses these industry pain points by delivering consistent performance across varying downhole conditions. As a factory-direct supply platform with direct partnerships with ISO 9001:2015 certified manufacturers, we ensure each batch meets strict quality standards. This product enhances drilling fluid viscosity with an apparent viscosity of 55 MPa.S and controls fluid loss to 23 ml, critical parameters for maintaining wellbore stability and improving drilling efficiency in both onshore and offshore operations.

Key Applications in Oilfield Operations

High Viscosity Polyanionic Cellulose PAC is primarily used as a viscosifier and fluid loss reducer in water-based drilling fluids. Its unique molecular structure provides excellent suspension properties for cuttings removal and helps maintain hole integrity by forming a stable filter cake. This White PAC Oil Drilling Agent is compatible with various drilling fluid additives, making it suitable for conventional and complex well drilling scenarios, including extended reach wells and horizontal drilling applications.

Critical Specifications for Drilling Performance

The performance of Polyanionic Cellulose in drilling fluids depends on several key parameters. The Degree of Substitution (D.S) of 0.9 ensures optimal solubility and salt tolerance, essential for maintaining viscosity in brine-based mud systems. A moisture content of 10% guarantees product stability during storage and prevents clumping during mixing. The apparent viscosity of 55 MPa.S provides the necessary fluid thickness to suspend drill cuttings, while the 23 ml fluid loss value minimizes formation damage by controlling filtrate invasion into the reservoir—parameters we validate through rigorous batch testing.

Value Beyond Compliance: Long-Term Operational Benefits

Choosing our High Viscosity PAC Polymer translates to tangible operational advantages. ISO 9001:2015 certification ensures adherence to global quality management standards, reducing the risk of non-compliance with international drilling regulations. Our 4000 Tons/Year production capacity guarantees consistent supply, eliminating project delays caused by material shortages. Unlike lower-grade products that require frequent dosage adjustments, our HV-PAC Polymer maintains stable performance over extended use, reducing overall chemical consumption and operational costs.

Quality Assurance You Can Verify

Certificate of Analysis & Documentation

Every order includes a batch-specific Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS). Detailed test records, including viscosity curves and fluid loss measurements, are available upon request for quality verification. For customers requiring additional documentation, we can provide factory inspection reports and ISO 9001:2015 certification copies to support regulatory compliance.

Storage & Handling

• Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
• Keep away from incompatible materials, food and feed sources.
• Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
• Follow good industrial hygiene practices. Avoid inhalation and skin contact.
• Refer to MSDS for detailed storage and safety instructions.
