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.

We claim: 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 that control fluid flow through the downhole tool; a cont
We claim: 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 that control fluid flow through the downhole tool; a controller for activating the actuator; a tag that is fixed relative to casing in the wellbore, wherein the downhole tool is passable through the casing and by the tag; and a sensor disposed on the downhole tool for detecting the tag in the wellbore, wherein the sensor comprises a radio frequency tag reader and detection of the tag is transmitted to the controller, thereby causing the actuator to operate the downhole tool. 2. The apparatus of claim 1, wherein the flow downhole tool comprises a movable sleeve adapted to open or close one or more ports. 3. The apparatus of claim 1, wherein the downhole tool is repeatedly actuated and unactuated. 4. The apparatus of claim 1, wherein the downhole tool comprises a diverter tool. 5. The apparatus of claim 4, wherein when the diverter tool comprises: an upper sub; a lower sub; a sliding sleeve disposed between the upper sub and lower sub; and at least one bypass port adapted to communicate between an interior and an exterior of the diverter tool, wherein the sliding sleeve is adapted to open and close the bypass ports. 6. The apparatus of claim 5, wherein the actuator activates the sliding sleeve to open the bypass ports. 7. The apparatus of claim 5, wherein the actuator activates the sliding sleeve to close the bypass ports. 8. The apparatus of claim 1 wherein when the downhole tool is disposed in the wellbore, the radio frequency tag reader sends a first signal and receives a second signal. 9. The apparatus of claim 1, wherein when the downhole tool is disposed in the wellbore, the radio frequency tag reader receives a signal. 10. The apparatus of claim 1, wherein the radio frequency tag reader detects a signal generated by the tag that is a radio frequency tag. 11. The apparatus of claim 10, wherein the radio frequency tag receives a first signal and sends a second signal. 12. the apparatus of claim 10, wherein the radio frequency tag comprises a battery adapted to increase the signal. 13. A method for activating a downhole tool, comprising: providing the downhole tool with a sensor; providing a tag fixed relative to casing in the wellbore; detecting the tag with the sensor while running the downhole tool through the casing; signaling detection of the tag and operating an actuator based on the signaling of the tag being detected, wherein the actuator activates the downhole tool between actuated and unactuated positions that control fluid flow through the downhole tool. 14. The method of claim 13, wherein the downhole tool. comprises a diverter tool. 15. The method of claim14, wherein the diverter tool comprises: an upper sub; a lower sub; a sliding sleeve disposed between the upper sub and lower sub; and at least one bypass port adapted to communicate between an interior and an exterior of the diverter tool, wherein the sliding sleeve is adapted to open and close the bypass ports. 16. The method of claim 15, wherein the actuator activates the sliding sleeve to close the bypass ports on the diverter tool. 17. The method of claim 15, wherein the actuator activates the sliding sleeve to open the bypass ports on the diverter tool. 18. The method of claim 13, wherein the sensor comprises a radio frequency tag reader. 19. The method of claim 18, wherein detecting the tag comprises sending a first signal from the radio frequency tag reader to the tag that is a radio frequency tag and receiving a second signal from the radio frequency tag. 20. The method of claim 18, wherein detecting the tag comprises receiving a signal generated by the tag that is a radio frequency tag. 21. The method of claim 18, wherein signaling the detection of the tag comprises transmitting a signal from the radio frequency tag reader to a controller. 22. The method of claim 21, wherein the controller activates the actuator.
