Abstract
An adjustable flow control device. In one aspect, the flow control device comprises a base pipe having one or more openings extending from an exterior to an interior of the base pipe; and a movable sleeve positioned along the interior of the base pipe, the movable sleeve having one or more associated openings extending from an exterior to an interior of the movable sleeve, and configured to rotate to a first position that aligns a first of the base pipe openings with a first of the movable sleeve openings.
Claims20
An adjustable flow control device, comprising:
- a base pipe having two or more base pipe openings extending from an exterior of the base pipe to an interior of the base pipe, wherein the two or more base pipe openings are axially offset from one another;
- and
- a movable sleeve positioned along at least a portion of the interior of the base pipe, the movable sleeve having two or more associated movable sleeve openings extending from an exterior of the movable sleeve to an interior of the movable sleeve, the two or more associated movable sleeve openings axially offset from one another and radially offset from one another, the movable sleeve configured to rotate to a first position that aligns a first of the two or more base pipe openings with a first of the two or more movable sleeve openings and rotate to a second position that aligns a second of the two or more base pipe openings with a second of the two or more movable sleeve openings.
A method for modifying an adjustable flow control device, comprising:
- providing an adjustable flow control device, the adjustable flow control device including:
- a base pipe having two or more base pipe openings extending from an exterior of the base pipe to an interior of the base pipe, wherein the two or more base pipe openings are axially offset from one another;
- and
- a movable sleeve positioned along at least a portion of the interior of the base pipe, the movable sleeve having two or more associated movable sleeve openings extending from an exterior of the movable sleeve to an interior of the movable sleeve, the two or more associated movable sleeve openings axially offset from one another and radially offset from one another;
- and
- rotating the movable sleeve from a first position that aligns a first of the two or more base pipe openings with a first of the two or more movable sleeve openings to a second position that aligns a second of the two or more base pipe openings with a second of the two or more movable sleeve openings.
A well system, comprising:
- a base pipe having two or more base pipe openings extending from an exterior of the base pipe to an interior of the base pipe, wherein the two or more base pipe openings are axially offset from one another;
- a screen subassembly, including
- a filter medium disposed about the base pipe for receiving production fluid from
- an oil and gas formation;
- and
- a flow control module fluidly coupled beneath the screen subassembly, the flow control module including a movable sleeve positioned along at least a portion of the interior of the base pipe, the movable sleeve having two or more associated movable sleeve openings extending from an exterior of the movable sleeve to an interior of the movable sleeve, the two or more associated movable sleeve openings axially offset from one another and radially offset from one another, the movable sleeve configured to rotate to a first position that aligns a first of the two or more base pipe openings with a first of the two or more movable sleeve openings and rotate to a second position that aligns a second of the two or more base pipe openings with a second of the two or more movable sleeve openings.
