Reversible invert-emulsion reservoir drill-in fluid system
Deposit an oil-wet filtercake that reverts to a water-wet state once a low pH treatment is applied.
VERSA-WAY invert-emulsion filtercake breaker system slowly and uniformly reacts with the filtercake created by the VERSAPRO invert-emulsion reservoir drill-in fluid system, delaying breakthrough by more than 20 hours and enabling you to pull out the service tool or washpipe without incurring losses.
Designed for use in wells with temperatures greater than 200 degF [93 degC], the VERSA-WAY system is ideal for openhole completions that use stand-alone or expandable screens, and for use after openhole gravel-pack operations. The elevated viscosity of the system permits its use as a spacer or pill during displacement in openhole stand-alone applications.
