Abstract

Methods and apparatus are provided that permit downhole tools to be run into a well along with logging tools that can log the downhole tools into place by real time transmission of the data to a surface location. In one aspect, an apparatus includes a telemetry tool, a logging tool in communication with the telemetry tool and a downhole tool.

Claims

1. An apparatus for performing a wellbore operation comprising:

a wireless transmitter;

at least one logging tool in communication with the transmitter; and

at least one wellbore component, whereby the apparatus can be run into the wellbore on a tubular string.

2. The apparatus of claim 1, whereby the transmitter is an electromagnetic telemetry tool.

3. The apparatus of claim 2, whereby the at least one logging tool is a gamma ray tool.

4. The apparatus of claim 2, whereby the at least one logging tool is a reservoir interface tool.

5. The apparatus of claim 4, whereby the reservoir interface tool is a neutron tool.

6. The apparatus of claim 1, whereby the at least one wellbore component includes a perforating gun.

7. The apparatus of claim 6, wherein the perforating gun is a tubing conveyed perforating gun.

8. The apparatus of claim 1, wherein the at least one wellbore component includes a packer

9. The apparatus of claim 1, wherein the at least one wellbore component includes a bridge plug.

10. The apparatus of claim 1, wherein the at least one wellbore component includes a whipstock and an anchor to fix the whipstock in a predetermined position within the wellbore.

11. The apparatus of claim 10, further including a cutting tool temporarily disposed on the whipstock by means of a frangible connection.

12. The apparatus of claim 2 wherein the electromagnetic telemetry tool comprises:

a processor;

a battery connected to the processor; and

a transmitter/receiver disposed in communication with the processor.

13. The apparatus of claim 12 wherein the electromagnetic telemetry tool further comprises:

a modulator disposed in communication with the processor;

a preamplifier disposed in communication with the modulator; and

a power amplifier disposed in communication with the preamplifier and with the transmitter/receiver

14. The apparatus of claim 13 wherein the electromagnetic telemetry tool further comprises:

a pressure sensor; and

a temperature sensor, both sensors disposed in communication with the processor.

15. The apparatus of claim 3 wherein the gamma ray tool comprises a radiation detector

16. The apparatus of claim 15 wherein the gamma ray tool further comprises a telemetry tool interface disposed in communication with the electromagnetic telemetry tool.

17. The apparatus of claim 1, further comprising:

a surface system comprising a controller having input/output devices and a transmitter/receiver disposed in connection with the controller to communicate signals selectively with the transmitter and the logging tool.

18. The apparatus of claim 17 wherein the surface system further comprises a depth-determining system for determining a depth position of the logging tool.

19. A method for logging into place a wellbore component disposed on a tubular string, comprising:

lowering the wellbore component, an electromagnetic telemetry tool and a gamma ray tool disposed on the tubular string into a wellbore;

producing a partial log utilizing the gamma ray tool while the wellbore component is moved adjacent a correlative formation marker;

comparing the partial log to a well log to determine a depth position adjustment; and

adjusting a position of the wellbore component according to the depth position adjustment.

20. The method of claim 19, further comprising:

transmitting signals representing data collected by the gamma ray tool to a surface system.
