Abstract
A system for use in a wellbore includes a tubing having an inner bore and flow switcher assembly. The flow switcher assembly including a first conduit coaxial with the tubing inner bore and a second conduit formed annularly around the first conduit. One of the first and second conduits is adapted to carry production fluid flow, and the other one of the first and second conduits is adapted to carry injection fluid flow. The flow switcher assembly includes ports in communication with the first and second conduits to enable cross-over flow. In addition, one or more valves may be provided to control fluid flow through the ports.

A system for use in a wellbore, comprising:
- a tubing having an inner bore;
- a flow switcher assembly including:
- a first conduit coaxial with the tubing inner bore, and
- a second conduit formed annularly around the first conduit,
- one of the first and second conduits adapted to carry production fluid flow and the other one of the first and second conduits adapted to carry injection fluid flow;
- and
- a retrievable plug attached in the first conduit.
A system for use in a wellbore, comprising:
- a tubing having an inner bore;
- a flow switcher assembly including:
- a first conduit coaxial with the tubing inner bore, and
- a second conduit formed annularly around the first conduit,
- one of the first and second conduits adapted to carry production fluid flow and the other one of the first and second conduits adapted to carry injection fluid flow;
- a pipe connected below the flow switcher assembly;
- a first annular region outside the tubing above the flow switcher assembly;
- and
- a second annular region outside the pipe below the flow switcher assembly.
An apparatus for use in a wellbore having a plurality of zones, comprising:
- a first pipe having a bore;
- a second pipe having a bore through which the first pipe is passed through, an annular region defined between an outer wall of the first pipe and an inner wall of the second pipe to provide a first fluid path in communication with a first zone;
- and
- an assembly having a conduit sealably mounted through the first and second pipes to allow fluid communication between the first pipe bore and the outside of the second pipe to provide a second, separate fluid path in communication with another zone.
A method for use in a well having a plurality of zones, comprising:
- injecting fluids through a first fluid path including an annular region between a first tubing and a second tubing, the fluid path being in communication with a first zone;
- and
- producing fluids through a second fluid path in communication with a second zone and including the inner bore of the first tubing, a region outside the second tubing, and a conduit member sealably mounted through side walls of the first and second tubings.
A method of simultaneously providing injection and production fluids to or from a plurality of zones in a well, comprising:
- injecting fluids through a first fluid path in communication with a first zone including an inner bore of a first tubing, a region outside a second tubing, and a conduit member sealably mounted through side walls of the first and second tubings;
- and
- producing fluids through a second fluid path including an annular region between the first tubing and the second tubing, the second fluid path being in communication with a second zone.
A system for use in a wellbore, comprising:
- a tubing having an inner bore and defining a well annulus between the tubing and the wellbore;
- and
- a flow switcher including:
- a flow switcher housing defining a first fluid path providing fluid communication between the inner bore and a first formation zone, and a second fluid path providing fluid communication between the inner bore and a second formation zone, and
- at least one flow control device to control flow through at least one of the first fluid path and the second fluid path.
A system for use in a wellbore, comprising:
- a tubing having an inner bore and defining a well annulus between the tubing and the wellbore;
- a flow switcher housing;
- the flow switcher housing defining a first fluid path providing fluid communication between the inner bore and a first formation zone, the first fluid path providing substantially a full bore flow, and
- the flow switcher housing further defining a second fluid path providing fluid communication between the inner bore and a second formation zone, the second fluid path providing substantially a full bore flow.
