Polyanionic Cellulose Polymer (Regular/High Viscosity) – Premium PAC-REG
Innova Corporate (India) is a world-class manufacturer and global exporter of Polyanionic Cellulose Polymer (Regular), widely recognized in the industry as PAC-REG or PAC-HV. This technical-grade Carboxy Methyl Cellulose (CMC-HV) is a high-yielding, premium polymer designed to serve dual functions: as a potent viscosifier and a superior fluid loss reducer in a variety of water-based drilling fluid systems.
Detailed Description & Benefits:
- Multi-Functional Polymer: Innova PAC-REG is engineered to provide maximum carrying capacity (viscosity) while simultaneously creating a thin, resilient filter cake to inhibit fluid migration into the formation.
- High-Performance Dispersion: It is readily dispersible across various water-based muds, offering excellent ion tolerance against salt, calcium, and other common contaminants found in complex geologies.
- Scale Inhibition: Beyond rheology control, it acts as a secondary scale inhibitor, ensuring the long-term integrity of drilling equipment and the borehole.
Applications & Technical Stability:
Innova’s PAC-Regular is successfully utilized in fresh water, sea water, and brine-based drilling systems. Its performance is heavily dependent on the polymer's concentration in the water phase and its effective absorption on solids. To maintain optimal rheological properties, it is essential to monitor and replace the polymer lost on drilled cuttings during the circulation cycle.
Thermal Performance:
- Temperature Resistance: PAC-REG demonstrates exceptional thermal stability up to 300°F (149°C) in laboratory conditions. In field applications, proper mud treatment can further extend this thermal threshold, making it suitable for deep and high-temperature wells.
