High-performance brine-compatible drilling fluids
Maintain efficient well control in the Bakken.
EnduraDril inhibitive divalent water-based drilling fluid is a low-solids, nondispersed system that is highly compatible with the Bakken base brine. The EnduraDril fluid is versatile in applications for the Bakken plays and is proven to match and exceed the performance of the traditional oil-based mud (OBM).
EnduraDril fluid chemistry works with existing produced water for a full range of clear water drilling to a fluid exhibiting inhibitive characteristics and a rheological profile like OBM yet solids-free.
Because EnduraDril fluid is saltwater based, impacts from saltwater contamination are largely reduced. Depending on the salinity of saltwater inflow, density is minimally impacted. Viscosity dilution, if encountered, is easily recovered.

Highly compatible with produced brine fluids, including Bakken produced brine.
Solids-free fluid brings multiple operational benefits and eliminates the need to change fluid type between the vertical and the curve sections.
