Q1: What is the primary function of PAC Drilling Grade in drilling fluids?
A1: PAC Drilling Grade acts as a fluid loss reducer and viscosifier, improving drilling fluid properties, stabilizing boreholes, and minimizing filtration loss.
Q2: What is the difference between PAC HV and PAC LV?
A2: PAC HV (High Viscosity) provides strong viscosity and suspension, while PAC LV (Low Viscosity) focuses on fluid loss control with minimal impact on viscosity.
Q3: Is PAC Drilling Grade suitable for both freshwater and brine drilling fluids?
A3: Yes, Unionchem PAC Drilling Grade performs excellently in both freshwater and brine-based mud systems, with strong salt resistance.
Q4: What is the typical dosage of PAC in drilling fluids?
A4: Typical dosage is 0.2–1.0% depending on drilling conditions and mud system. We provide technical guidance for optimal application.
Q5: Can you provide technical and regulatory documents?
A5: Yes, we supply COA, MSDS, TDS, and offer technical support for your field operations and compliance needs.
