Double Poppet Wash-Down Shoe (DPWDS)
The wash-down shoe is a poppet, steel body, set-type
shoe. It is run as the bottom tool on screen and liner
assemblies, usually in open-hole completions.
The wash-down shoe enables complete circulation
out the bottom of the open-hole sand control
assembly. This can be important in the event that
circulation is used to assist in working the assembly
completely in the hole. The wash-down shoe prevents
fluid flow back while allowing fluid flow through the assembly.
