Abstract
Devices for controlling the flow of fluids past a location in a wellbore and methods for using such devices are disclosed. Embodiment devices are configured such that the throughbore is maximized because of the devices' thin cross sectional length. Embodiment devices may be optimized to expand into larger casing sizes by use of a multi-part cone system while maintaining the thin cross section. Embodiment devices may also permit the plug to be communicated into the well with the flow control devices, reducing the fluid volume required to treat well stages separated by the disclosed embodiment devices.
Claims21
A downhole tool having a run-in state and a set state, the downhole tool comprising:
- A mandrel having in interior surface defining a passage therethrough and an exterior surface;
- a plug seat;
- a first setting ring;
- and
- an element, a cone having a first angular surface and a second angular surface, a cone extension and at least one slip positioned below the first setting ring and around the mandrel;
- wherein
- in the set state, the at least one slip engages the cone extension;
- and
- engagement of a plug on the plug seat prevents fluid communication through the passage.
A tubing baffle having a run-in state and a set state, the tubing baffle comprising:
- A mandrel having in interior surface defining a passage therethrough and an exterior surface;
- a plug seat;
- a first setting ring and a bottom section;
- an element, and at least one slip positioned below the setting ring and around the mandrel;
- and
- a plug;
- wherein
- the plug is configured to engage the plug seat to prevent fluid communication through the mandrel passage;
- the plug is engaged with the tubing baffle in the run-in state and in the set state.
A method for installing a flow control device into a well, the method comprising:
- connecting the flow control device to a wireline string, the flow control device comprising a mandrel with an element therearound, a plug seat, a plug in communication with the plug seat, an upper setting ring, a slip, and a bottom section;
- placing the flow control device into a well;
- conveying the flow control device to a desired location in the well;
- moving the upper setting ring and the bottom section toward one another;
- expanding the slip radially outward to engage a casing in the well;
- releasing the flow control device from the wireline string;
- and
- removing the wireline string from the well.
