Product Description
Aquathin is a high-performance Salt-Tolerant Copolymer Thinner specifically engineered for water-based drilling fluids in deep and ultra-deep well applications. As a highly effective Salt-Tolerant Copolymer Thinner, it maintains optimal rheological stability in the presence of severe electrolyte contamination from salt, gypsum, and cement, while also preventing high-temperature gelation and minimizing thermal flocculation. Under extreme drilling conditions, including ultra-high temperatures and elevated mud weights, this Salt-Tolerant Copolymer Thinner further inhibits shale hydration, enhances filter cake quality, and ensures long-term drilling fluid performance, supporting safer and more efficient operations.
Applications/Functions
Deflocculates water-based drilling fluids in deep, ultra-deep, and high-temperature wells;
Minimizes thermal flocculation and reduces shear strength development under dynamic downhole conditions;
Maintains fluid stability in salt-saturated, gypsum, or cement-contaminated environments;
Improves filter cake integrity and inhibits shale hydration to enhance wellbore stability;
Supports high-density fluid systems without compromising rheological control.
Advantages
Exceptional thermal stability up to 500°F (260°C), suitable for the most challenging well conditions;
High salt tolerance and resistance to divalent ions (e.g., Ca²⁺, Mg²⁺), ensuring broad applicability;
Liquid formulation allows direct addition to agitated mud pits for rapid and uniform dispersion;
Environmentally friendly and compliant with international environmental standards;
Significantly reduces viscosity (over 80% reduction rate) and enhances fluid efficiency;
Compatible with other water-based drilling fluid additives.
Typical Properties
Appearance: Dark viscous liquid
pH: 11–12
Viscosity Reduction Rate: >80%
Recommended Treatment
A typical dosage of 1–2% (v/v) is recommended for most applications. However, specific drilling conditions-such as temperature, contamination levels, and mud weight-may require adjustments to achieve optimal performance. It is advised to add the product directly to the circulating system under agitation for immediate integration and effectiveness. Pilot testing is recommended to determine the ideal concentration for specific operational needs.
