Reversible invert-emulsion reservoir drill-in fluid system

FAZEPRO drill-in fluid system

Drill fast while oil-wet. Complete clean while water-wet.

FAZEPRO reversible invert-emulsion reservoir drill-in fluid system is the industry’s most uniquely engineered invert-emulsion reservoir drill-in fluid. As an oil-based fluid, it deposits an oil-wet filtercake. Once a low-pH (acid) breaker treatment is applied, the filtercake reverts to a water-wet state. The FAZEPRO system combines the drilling advantages of an invert-emulsion with the completion benefits of water-based systems. It provides the low fluid loss, high ROP, and excellent wellbore stability of an oil-based fluid with the simple filtercake dispersion and dissolution of its water-based counterpart. The FAZEPRO system is designed for drilling both open- and cased hole completions.

Reversible invert-emulsion reservoir drill-in fluid


  • Faster drilling and stable wellbore
  • Reduced waste generation
  • Environmental acceptability
  • Better production rates
  • Cleanup through all openhole completions, including gravel packs
  • Elimination of remedial treatments
  • No flowback required for injector wells
The FAZE-OUT breaker system completely dissolves FAZEPRO system filtercakes by removing the bridging elements that bind the filtercake together.
