Reversible oil-base reservoir drill-in fluid

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-base 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-base systems. It provides the low fluid loss, high ROP, and excellent wellbore stability of an oil-base fluid with the simple filtercake dispersion/dissolution of its water-base counterpart. The FAZEPRO system is designed for drilling both open- and cased-hole completions.
