Abstract
A system can include a tubing string, a filter screen, and an interval control valve deployed downhole in a wellbore. The tubing string may not have perforations. A first annulus may be formed between an exterior of the tubing string and a subterranean formation. The filter screen can be coupled to the exterior of the tubing string and can form a second annulus between the filter screen and the exterior of the tubing string. The interval control valve can be positioned inline with the exterior of the tubing string. The interval control valve can control flow of fluid between the second annulus and the interior of the tubing string.
Claims20
A system comprising:
- a tubing string positionable downhole in a wellbore and forming a first annulus between an exterior of the tubing string and a subterranean formation of the wellbore when positioned downhole;
- a first filter screen coupleable to the exterior of a first tubing joint of the tubing string and configurable to form a second annulus between the first filter screen and the exterior of the first tubing joint;
- an interval control valve positionable inline with the exterior of the tubing string and configurable to control flow of fluid between the second annulus and an interior of the tubing string;
- a second filter screen coupleable to the exterior of a second tubing joint of the tubing string and configurable to form a third annulus between the second filter screen and the exterior of the second tubing joint;
- and
- a shroud positionable on the exterior of the tubing string, the shroud comprising:
- a first end coupleable to the first filter screen;
- and
- a second end coupleable to the second filter screen to form a fluidic pathway between the second annulus and the third annulus.
A method comprising:
- deploying a tubing string downhole in a wellbore, the tubing string forming a first annulus between an exterior of the tubing string and a subterranean formation;
- filtering, by a first filter screen coupled to the exterior of the tubing string, fluid between the first annulus and a second annulus formed between the first filter screen and the exterior of a first tubing joint of the tubing string;
- filtering, by a second filter screen coupled to the exterior of a second tubing joint of the tubing string, fluid between the first annulus and a third annulus formed between the second filter screen and the exterior of the second tubing joint;
- forming, by a shroud positioned on the exterior of the tubing string, a fluidic pathway between the second annulus and the third annulus, the shroud being coupled at a first end to the first filter screen and being coupled at a second end to the second filter screen;
- and
- controlling, by an interval control valve positioned inline with the exterior of the tubing string, a flow path of the fluid between the second annulus and an interior of the tubing string.
An interval control valve system comprising:
- a first filter screen coupleable to an exterior of a first tubing joint of a tubing string that is positionable downhole in a wellbore, the tubing string configurable to form a first annulus between the exterior of the tubing string and a subterranean formation when positioned downhole, the first filter screen configurable to form a second annulus between the first filter screen and the exterior of the tubing string;
- an interval control valve positionable inline with the exterior of the tubing string and configurable to control flow of fluid between the second annulus and an interior of the tubing string;
- a second filter screen coupleable to the exterior of a second tubing joint of the tubing string and configurable to form a third annulus between the second filter screen and the exterior of the second tubing joint;
- and
- a shroud positionable on the exterior of the tubing string, the shroud comprising:
- a first end coupleable to the first filter screen;
- and
- a second end coupleable to the second filter screen to form a fluidic pathway between the second annulus and the third annulus.
