Polyanionic Cellulose (PAC) is a staple in the oil drilling industry, offering essential functionalities for fluid management. However, PAC comes in different grades, primarily High Viscosity (HV) and Low Viscosity (LV), each suited for distinct applications within drilling fluid formulations. NINGBO INNO PHARMCHEM CO.,LTD. guides you through selecting the appropriate PAC grade for your needs.

The fundamental difference between PAC-HV and PAC-LV lies in their molecular weight and viscosity-building capacity. PAC-HV, with its higher molecular weight, is specifically engineered to provide significant viscosity enhancement and robust fluid loss control. It is an excellent drilling fluid additive viscosity enhancer, particularly useful in systems where suspending cuttings and maintaining wellbore stability are paramount. When you need strong rheological properties, PAC-HV is the preferred choice.

Conversely, PAC-LV offers lower viscosity but still provides effective fluid loss control. It is often selected for applications where maintaining a lower viscosity profile is desired, perhaps in certain completion fluids or when seeking precise rheological adjustments without excessive thickening. While both grades are excellent PAC-HV fluid loss reducers and PAC-LV fluid loss reducers respectively, their impact on fluid viscosity differs.

The selection between PAC-HV and PAC-LV hinges on the specific requirements of the drilling fluid system. For instance, in high-temperature, high-pressure (HTHP) environments, or in drilling operations where cuttings carrying capacity is critical, PAC-HV is often favored. Its superior viscosity-building properties contribute to better suspension of drilled solids, preventing bridging and stuck pipe incidents. This highlights the diverse nature of polyanionic cellulose oilfield application.
