Polyanionic Cellulose
Polyanionic Cellulose (PAC) is a high-performance, water-soluble polymer derived from cellulose and chemically modified to enhance its functional properties. It is an essential additive in drilling fluids, crucial for controlling water loss and improving fluid rheology, thereby contributing to efficient and stable wellbore construction.
- Leverage Polyanionic Cellulose drilling fluid additive for superior filtrate reduction in water-based muds.
- Enhance wellbore integrity with PAC HV rheology control, ensuring stability in challenging conditions.
- Utilize PAC LV fluid loss reducer to minimize fluid loss without significant rheology changes, optimizing drilling operations.
- Ensure efficient drilling with water-based drilling fluid additives that offer excellent compatibility and rheological adjustment.
Key Advantages
Filtration Control Excellence
PAC acts as an excellent filtrate reducer, effectively minimizing fluid loss into formations, which is critical for maintaining wellbore stability and preventing formation damage, as supported by extensive use of oil drilling chemicals PAC.
Rheology Optimization
Both PAC HV and PAC LV contribute to the rheological properties of drilling fluids, allowing for better control of viscosity and suspension of drill cuttings, essential for efficient hole cleaning and overall drilling performance.
Wellbore Integrity
By reducing fluid loss and forming a protective filter cake, PAC helps prevent wellbore collapse and differential sticking, significantly improving wellbore stability PAC during drilling operations.
Key Applications
