Abstract
A control system may comprise a flow control device, wherein the flow control device comprises water floats and gas floats and a regulatory valve connected to the flow control device through a control line. An autonomous flow control device may comprise a housing, one or more floats disposed within the housing, one or more protrusions connected to the outside of the housing, and an outlet disposed in the housing.
Claims20
A control system comprising:
- a flow control device, wherein the flow control device comprises at least one water float and at least one gas float, the flow control device operable to rotate due to protrusions of the flow control device;
- and
- wherein the at least one water float is disposed between a first set of walls and wherein the at least one gas float is disposed between a second set of walls.
A control system comprising:
- a housing comprising a chamber;
- a first float and a second float disposed within the chamber, wherein the first float is disposed between a first set of walls, and wherein the second float is disposed between a second set of walls, the control system operable to rotate due to protrusions of the control system, to control a flow of formation fluid through the chamber, wherein the control system is disposed in a wellbore;
- and
- openings disposed along an exterior surface of the housing.
1 more element
A control system comprising:
- a housing comprising protrusions and an internal chamber;
- and
- a first float and a second float disposed within the internal chamber, wherein each float comprises at least one gas float or at least one water float, wherein the first float is disposed between a first set of walls, and wherein the second float is disposed between a second set of walls, the control system operable to rotate due to the protrusions, to control a flow of formation fluid through the internal chamber, wherein the control system is disposed in a wellbore.
