EnduraDril
Inhibitive divalent water-based drilling fluid
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).
How it works
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.
Advantages
- Compatibility with Bakken base brine
- Faster drilling
- Enhanced hole cleaning
- Greater wellbore stability
Limitations
- Optimal performance in applications with mud density ≤13.5 lb/galUS (1.62 sg)
- Thermal stability ≤275 degF [135 degC]
