Patent ID: RE40308

Claim:
A system for injecting fluid into, and producing fluid from, multiple zones in a well bore, comprising: a tubular completion string, said completion string having a production fluid inlet port and an injection fluid outlet port; a production fluid flow path within said completion string; an injection fluid flow path within said completion string; a production fluid sleeve bypass channel connecting a portion of said injection fluid flow path above said production fluid inlet port to a portion of said injection fluid flow path below said production fluid inlet port; an injection fluid bypass channel connecting a portion of said injection fluid flow path above said injection fluid outlet port to a portion of said injection fluid flow path below said injection fluid outlet port; a production fluid conduit, said production fluid conduit being adapted to shift relative to said completion string to selectively conduct production fluid from said production fluid inlet port to said production fluid flow path; and an injection fluid conduit, said injection fluid conduit being adapted to shift relative to said completion string to selectively conduct injection fluid from said injection fluid flow path to said injection fluid outlet port.
