Introduction

In drilling fluids, few additives have stood the test of time like Polyanionic Cellulose (PAC) and Carboxymethyl Cellulose (CMC). Despite newer materials entering the market, these two remain indispensable in modern drilling operations.

Why Fluid Loss Control Matters

• Prevents filtrate invasion into formations

• Protects wellbore stability

• Reduces formation damage and non-productive time

PAC & CMC at Work

• PAC LV & R: Excellent for filtration control, fully soluble in water-based systems.

• CMC LV & HV: Improve viscosity, stabilize wellbores, and reduce seepage.

Excelex Quality Advantage
