Water-based fluids are often used due to their relatively low cost, the ease of acquiring the base fluid (water), and their low impact on the environment. QMax offers a wide variety of water-based fluids, which are classified based on the presence of a clay inhibitor, and the use of polymers for its formulation. Fluids selection depends on the composition of the water phase (pH, iconic content, etc.), viscosity builders (clay or polymers), and rheological control agents (deoflocculants or dispersants).
