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 transmitter for wireless conveyance of information to a surface system;

a radio frequency reader in communication with the transmitter;

a wellbore component positioned in the wellbore by using information provided by the radio frequency reader.

2. The apparatus of claim 1, wherein the wellbore component is selected from the group consisting of a packer, a bridge plug, perforating gun and combinations thereof.

3. The apparatus of claim 1, wherein the surface system is configured to analyze, consolidate and present data collected by the radio frequency reader.

4. The apparatus of claim 1, wherein the radio frequency reader is configured for communicating with radio frequency identification tags.

5. The apparatus of claim 1, further comprising a memory for storing data pertaining to the characteristics of formations surrounding the wellbore.

6. The apparatus of claim 1, further comprising a central processing unit.

7. The apparatus of claim 1, further comprising:

a memory for storing data pertaining to the characteristics of formations surrounding the wellbore; and

a central processing unit coupled to the memory.
