Celotech’s Poly-anionic Cellulose (PAC) is a premium-grade additive engineered for oilfield drilling applications, delivering critical performance enhancements:
✔ Superior Fluid Loss Control – Reduces API fluid loss by 40-60% in water-based mud systems
✔ Enhanced Rheological Properties – Improves low-shear-rate viscosity (LSRV) and gel strength
✔ Shale Stabilization – Effectively inhibits clay swelling and wellbore collapse
✔ Temperature Resistance – Stable performance up to 150°C (302°F) in high-pressure/high-temperature (HPHT) wells
Celopac® LV makes it easy to disperse and mix in water-based drilling fluids, thereby improving the efficiency and performance of drilling fluids. It can not only effectively control water loss, but also form a thin and tough mud cake to protect the well wall, reduce the carrying of drill cuttings, and improve the suspension capacity of drilling fluids.
Water-based drilling fluids (freshwater, seawater, brine)
Fluid loss control in vertical, directional, and horizontal wells
Completion and workover fluids
Low-solids mud systems
Environments requiring minimal viscosity build-up
With a proven track record in global oilfield operations, Celopac® LV offers the ideal balance of performance, reliability, and environmental safety. Its unique low-viscosity profile and robust salt tolerance make it the additive of choice for demanding fluid loss control in modern drilling practices.
