Baroid’s SOLUTION

Baroid DRIL-N™ Fluids are acid soluble and non-damaging drill-in fluids that help increase wellbore stability, provide effective fluid loss control, and enable high penetration rates, ultimately leading to maximum production.

5 © 2012 HALLIBURTON. ALL RIGHTS RESERVED.

BARADRIL-N™, BRINEDRIL-N™, and COREDRIL-N™ systemsare specially formulated with thermally-stable polymers for suspension and filtration control, and sized calcium carbonate bridging particles for low filtration rates.

Baroid’s SOLUTION

COREDRIL-N™ systems can prevent the alteration to core samples by containing only a small amount of passive emulsifiers which remain inactive until water contaminates the system.
