Drilling reagent ASDA PAC HV high viscosity

Drilling reagent ASDA PAC HV high viscosity (Polyanionic cellulose) is a carboxymethyl cellulose with an increased degree of substitution. In the process of drilling production and production oil, gas and water wells, polyanionic cellulose (PAC) used as additives for drilling fluids performs two functions - creates a filter layer at the walls of the well to minimize water losses and controls the rheology of liquid systems. Both water and organic solvents can serve as the basis of drilling fluids, but today's environmental protection requirements and technological features of well drilling processes determine the use of water-based drilling fluids in most cases.

ASDA PAC LV drilling reagent is low-viscosity (Polyanionic cellulose), used to increase the conditional viscosity and reduce the filtration rate of clay-free solutions and solutions with a low solid phase content. It is effective as a stabilizing reagent in all types of water-based drilling fluids, provides stabilization of the well walls during drilling of clay shales, and helps to reduce the solid phase in the drilling fluid. Reduces the filtration rate. It forms a thin and elastic filtration crust, which reduces the loss of drilling fluid, preserves the diameter of the annular space as much as possible and reduces hydraulic resistance in the wellbore. It is thermally stable and stable in highly mineralized environments (saturated solutions of sodium and potassium chlorides).
