METHOD OF ENHANCING CIRCULATION DURING DRILL-OUT OF A WELLBORE BARRIER USING DISSOLVABLE SOLID PARTICULATES

A fluid-impermeable barrier, used to isolate stimulated intervals in a reservoir during a multi-zone fracturing operation, may be removed from the wellbore which penetrates the reservoir using a circulating fluid containing dissolvable solid particulates. The dissolvable solid particulates bridge pe...

More Information
Summary:A fluid-impermeable barrier, used to isolate stimulated intervals in a reservoir during a multi-zone fracturing operation, may be removed from the wellbore which penetrates the reservoir using a circulating fluid containing dissolvable solid particulates. The dissolvable solid particulates bridge perforation clusters during clean-out of the wellbore and thus inhibit passage of the circulating fluid into the fracture network through the perforation clusters.
