Optimize filtercake removal with placement during the completion

VERSA-OUT water-based filtercake breaker system allows placement during the completion operation when it is possible to make direct contact with the invert-emulsion-based filtercake, even for difficult-to-contact situations like openhole gravel packs. This improves efficiency and uniformity of the filtercake removal process, improving injection and production in openhole wells with stand-alone screens or gravel packs. 

The delay in breakthrough can be extended by viscosifying the breaker system. Unviscosified systems will provide about 6 hours of delay under mild conditions. Viscosifying the system can almost double the delay time under the same conditions and will increase the time required for thorough filtercake destruction.
