Abstract

The present invention relates to apparatus and methods for remotely actuating a downhole tool. In one aspect, the present invention provides an apparatus for activating a downhole tool in a wellbore, the downhole tool having an actuated and unactuated positions. The apparatus includes an actuator for operating the downhole tool between the actuated and unactuated positions; a controller for activating the actuator; and a sensor for detecting a condition in the wellbore, wherein the detected condition is transmitted to the controller, thereby causing the actuator to operate the downhole tool.
In one embodiment, conditions in the wellbore are generated at the surface, which is later detected downhole. These conditions include changes in pressure, temperature, vibration, or flow rate. In another embodiment, a fiber optic signal may be transmitted downhole to the sensor. In another embodiment still, a radio frequency tag is dropped into the wellbore for detection by the sensor.

Claims (29)

1. An apparatus for activating a downhole tool in a wellbore, wherein the downhole tool has an actuated and unactuated positions, comprising:
an actuator for operating the downhole tool between the actuated and unactuated positions;
a controller for activating the actuator; and a sensor for detecting a condition in the wellbore, wherein the detected condition is transmitted to the controller, thereby causing the actuator to operate the downhole tool.
2. The apparatus of claim 1, wherein the condition in the wellbore is generated at the surface.
3. The apparatus of claim 1, wherein the sensor comprises a radio frequency tag reader.
4. The apparatus of claim 1, wherein the sensor comprises a radio frequency tag.
5. The apparatus of claim 1, wherein the downhole tool is operated to regulate fluid flow therethrough.
6. The apparatus of claim 1, wherein the downhole tool comprises a float valve.
7. The apparatus of claim 1, wherein the downhole tool comprises a flow control apparatus.
8. The apparatus of claim 7, wherein the flow control apparatus comprises a movable sleeve adapted to open or close one or more ports.
