Studies of Potassium Polyanionic Cellulose as a Drilling Fluid Additive
Keywords:
Potassium Polyanionic Cellulose, Drilling Fluid, Rheology, Filtration Control, AdditivesAbstract
Potassium Polyanionic Cellulose (K-PAC) is a widely used additive in water-based drilling fluids due to its excellent rheological and filtration control properties. This study investigates the effectiveness of K-PAC in enhancing the performance of drilling fluids under various conditions. Experiments were conducted to evaluate its influence on viscosity, yield point, gel strength, and filtration rate. Results demonstrate that K-PAC significantly improves drilling fluid stability, reduces fluid loss, and enhances lubricity, making it a suitable additive for challenging drilling environments.
