DRISTEMP® POLYMER

Dristemp® Polymer is a white, free-flowing synthetic polymer designed for high temperature drilling environments. It is compatible with all commonly used materials in water-based drilling fluids and is used for high temperature fluid loss control and inhibition of cutting and shales. In typical fresh and saltwater muds, it performed well up to 375 °F in lab testing and has shown excellent performance in formate fluids above 400 °F. In field muds, thermal stability might be expected to be higher.

Feature And Benefits
Works well at any salinity - Reduces differential sticking tendencies - Is calcium tolerant to 5,000 ppm - Temperature stable to 375 °F (190 °C) - Can improve thermal stability of whole mud system - Non-fermenting - Helps maintain the integrity of cuttings - Inhibits hydratable and sloughing shale - Increases the effectiveness of solids control equipment - Hydrates quickly without forming “fish-eyes” - Improves drilling fluid suspension properties specially where barite settling can be an issue - Works well in formate muds
Product Function
Dristemp® Polymer is an excellent replacement for starch in hard, salty systems particularly as increasing down hole temperatures degrade such products. It will also contribute to shale inhibition and cuttings integrity.
Recommended treatment
HTHP Fluid-loss control: 1 to 6 ppb Shale Inhibition /encapsulation: 0.5 to 3.0 ppb Completion & workover fluids: 0.5 to 6.0 ppb
