Abstract
A system for completing a well with multiple zones of production includes a casing having a plurality of valves that are integrated therein for isolating each well zone. Communication is established between each underlying formation and the interior of the casing, and a treatment fluid is delivered to each of the multiple well zones. Mechanisms for actuating one or more of the valves include, but are not limited to, a dart, a drop ball, a running tool, and a control line actuating system.
Claims9
A system for use in a wellbore having a plurality of well zones, comprising:
- a casing deployed in the wellbore;
- and
- a plurality of valves connected to the casing, each valve for establishing communication between the casing and a well zone;
- wherein the casing is fixed to the wellbore by cement,
- wherein at least one of the valves comprises a filter moveable between a filtering position at which the filter is aligned with at least one port of the valve and another position in which the filter is not aligned with said at least one port.
A system for use in a wellbore having a well zone, comprising:
- a casing deployed in the wellbore, the casing having an axial bore therein;
- and
- a valve connected to the casing for establishing communication between the casing and the well zone, the valve moveable between an open position wherein a flowpath exists between the axial bore of the casing and the well zone and a closed port position wherein the flowpath is interrupted,
- wherein the casing is fixed to the wellbore by cement, the valve has a selectable filtering position to filter fluid communicated from the well zone, and the valve is adapted to, in the selectable filtering position, filter sand or proppant from the fluid communicated from the well zone.
