Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) Published: — with international search report (Art. 21(3)) = (54) Title: SHUNT SYSTEM FOR DOWNHOLE SAND CONTROL COMPLETIONS (57) : A downhole sand control completion system includes a completion string extendable within a wellbore and including one or more sand control screen assemblies arranged about a base pipe, each sand control screen assembly including one or more sand screens positioned about the base pipe. A shunt system is positioned about an exterior of the base pipe to receive and redirect a gravel slurry flowing in an annulus defined between the completion string and a wellbore wall. A return tube is positioned about the exterior of the base pipe and extends longitudinally along a portion of the completion string. The return tube defines a plurality of openings to receive a portion of a fluid in the annulus into the return tube to be conveyed into an interior of the base pipe via the return tube.
