Abstract
A communication unit may be used within a wellbore tool string in communication with a surface unit and comprising at least one downhole tool. The communication unit may include a housing defining a chamber therein and an electronics board disposed within the chamber. The electronics board comprising a processing circuit. The processing circuit may be configured to perform receiving an electronic signal from one of the surface unit and the at least one downhole tool, processing the electronic signal, and transmitting the processed electronic signal to the other of the surface unit and the at least one downhole tool.
Claims20
A communication unit for use within a wellbore tool string in communication with a surface unit and comprising at least one downhole tool, the communication unit comprising:
- a housing defining a chamber therein;
- an electronics board disposed within the chamber, the electronics board comprising a processing circuit;
- a first signal line configured to provide electronic communication between the surface unit and the electronics board;
- a second signal line configured to provide electronic communication between the electronics board and the at least one downhole tool;
- and
- a feedthrough bypass configured to provide direct electronic communication between the first signal line and the second signal line;
- wherein the processing circuit is configured to perform:
- receiving an electronic signal from one of the surface unit and the at least one downhole tool, processing the electronic signal, and transmitting the processed electronic signal to the other of the surface unit and the at least one downhole tool.

A wellbore tool string in communication with a surface unit, the wellbore tool string comprising:
- a top connector configured to couple to a wireline;
- a communication unit;
- a wellbore tool;
- and
- a tandem sub or tandem seal adapter coupled between the communication unit and the wellbore tool;
- wherein the communication unit comprises:
- a housing defining a chamber therein;
- an electronics board disposed within the chamber, the electronics board comprising a processing circuit;
- a first signal line configured to provide electronic communication between the surface unit and the electronics board;
- a second signal line configured to provide electronic communication between the electronics board and the at least one downhole tool;
- and
- a feedthrough bypass configured to provide direct electronic communication between the first signal line and the second signal line:
- wherein the processing circuit is configured to perform:
- receiving an electronic signal from one of the surface unit and the at least one downhole tool, processing the electronic signal, and transmitting the processed electronic signal to the other of the surface unit and the at least one downhole tool.

A method of wellbore communication, the method comprising:
- providing a tool string comprising:
- a communication unit;
- and
- a wellbore tool;
- providing a surface unit configured to control the tool string;
- deploying the wellbore tool in a wellbore using a wireline;
- transmitting, from one of the surface unit and the wellbore tool, an electronic signal to the communication unit;
- processing the electronic signal with the communication unit;
- and
- transmitting the processed electronic signal to the other of the surface unit and the wellbore tool;
- wherein the communication unit comprises:
- a housing defining a chamber therein;
- an electronics board disposed within the chamber, the electronics board comprising a processing circuit;
- a first signal line configured to provide electronic communication between the surface unit and the electronics board;
- a second signal line configured to provide electronic communication between the electronics board and the wellbore tool;
- and
- a feedthrough bypass configured to provide direct electronic communication between the first signal line and the second signal line;
- and
- wherein the method further comprises:
- blocking electronic communication between the first signal line and the second signal line via the feedthrough bypass in response to a determination that the processing circuit is in an operable state, and
- enabling electronic communication between the first signal line and the second signal line via the feedthrough bypass in response to a determination that the processing circuit is in an inoperable state.
