Abstract

Combined wireline and wireless apparatus and related methods are disclosed herein. An example apparatus includes a tool string including a tool bus and a first acoustic repeater coupled to the tool string. The first acoustic repeater is to communicate with a second acoustic repeater to exchange data. The second acoustic repeater is communicatively coupled to a first tool. The first tool is not communicatively coupled to the tool bus.

First claim

1. A system comprising:
a wireline tool string including a tool bus; and
a first acoustic repeater mechanically coupled to the tool string, the first acoustic repeater to communicate with a second acoustic repeater to exchange data, the second acoustic repeater communicatively coupled to a first tool disposed below an mechanical obstruction relative to a surface when the tool string is disposed in a wellbore, the first tool is not communicatively coupled to the tool bus, and the mechanical obstruction prevents electrical communication between the tool bus and the first tool, and
a downhole cable coupled to the tool string for deploying the tool_string in the wellbore, the cable including a first set of electrical lines, the first acoustic repeater to transmit the data to a surface computer via the first set of electrical lines.

2. The system of claim 1 , wherein the obstruction is a second tool of the tool string.

3. The system of claim 1 , further including a propagation medium coupled to the obstruction, the propagation medium to relay the data between the first acoustic repeater and the second acoustic repeater.

4. The system of claim 3 , wherein the propagation medium includes a first and second propagators movable in the wellbore along with the mechanical obstruction.

5. The system of claim 1 , wherein the first acoustic repeater is communicatively coupled to the tool bus.

6. The system of claim 5 , wherein the first acoustic repeater includes a controller, the controller coupled to the tool bus.

7. The system of claim 1 , wherein the first tool is coupled to the tool string via a threaded connection.

8. The system of claim 1 , wherein the cable includes a second set of electrical lines and the tool string includes a second tool, the tool bus to transmit data between the second tool and the surface computer via the second set of electrical lines.

9. The apparatus of claim 1 , wherein the first tool is mechanically coupled to a third acoustic repeater, the first acoustic repeater to communicate with the first tool via the second acoustic repeater and third acoustic repeater.

10. The system of claim 1 , wherein the first tool comprises a pressure gauge.

11. The system of claim 1 , wherein the mechanical obstruction prevents deployment of the wireline tool string below the obstruction.

12. The system of claim 1 , wherein the first tool is mechanically coupled to the mechanical obstruction.

13. A method comprising:
deploying a wireline tool string in a wellbore using a cable having a set of electrical lines coupled to the wireline tool string, the wireline tool string including a first acoustic repeater and a tool bus;

by executing instructions with a processor:
setting a mechanical obstruction in the wellbore via the wireline tool string, wherein the mechanical obstruction prevents deployment of the wireline tool string below the mechanical obstruction;
communicating first data from the first acoustic repeater to a second acoustic repeater, the second acoustic repeater not communicatively coupled with the tool bus and communicatively coupled with a first tool disposed in the wellbore below a mechanical obstruction relative to a surface when the wireline tool string is disposed in the wellbore, the second acoustic repeater to transmit second data to the first acoustic repeater; and
transmitting the second data from the first acoustic repeater to the processor via the set of electrical lines of the cable.

14. The method of claim 13 ,
wherein the mechanical obstruction is a pressure barrier and wherein the method further includes:
analyzing the second data; and
one of unsetting the wireline tool string from the second tool pressure barrier or adjusting a setting of the second tool pressure barrier via the wireline tool string based on the analysis.

15. The method of claim 14 , wherein the first tool is a pressure gauge.

16. The method of claim 13 , wherein the wireline tool string includes a second tool, and
wherein the method further includes:
transmitting the second data to the processor via a first front-end surface interface; and
transmitting third data from the second tool to the processor via a second frontend surface interface.

17. The method of claim 16 , further including transmitting fourth data from the processor to the first acoustic repeater via the first front-end surface interface, the first acoustic repeater to transmit the fourth data to the first tool via the second acoustic repeater.

18. The method of claim 17 , further including transmitting fifth data from the processor to the second tool via the second front-end surface interface, the transmitting of the fifth data via the second front-end surface interface to occur at substantially the same time as the transmitting of the fourth data via the first front-end surface interface.

19. The method of claim 13 , further including transmitting the second data from the first acoustic repeater to the processor via the tool bus of the tool string.

20. A method comprising:
disposing a pressure gauge in a wellbore using a wireline tool string deployed via a cable in a wellbore, the pressure gauge to be coupled to a first acoustic repeater;
setting a pressure barrier in the wellbore via the wireline tool string, the pressure gauge to be disposed below the pressure barrier relative to a surface, the tool string including a second acoustic repeater mechanically coupled to the tool string;
accessing, by executing an instruction with a processor and via the second acoustic repeater, first pressure data collected by the pressure gauge, the first pressure data to be transmitted to the second acoustic repeater via the first acoustic repeater;
increasing, by executing an instruction with the processor, a pressure in wellbore;
accessing, by executing an instruction with the processor and via the second acoustic repeater, second pressure data collected by the pressure gauge after the increasing of the pressure in the wellbore;
performing, by executing an instruction with the processor, a comparison of the first pressure data and the second pressure data; and
one of unsetting the wireline tool string from the pressure barrier or adjusting the setting of the pressure barrier via the wireline tool string based on the comparison.

21. The method of claim 20 , further including comparing a pressure differential between the first pressure data and the second pressure data to a threshold pressure differential, the one of the unsetting the tool string from the pressure barrier or adjusting the setting of the pressure barrier based on the threshold pressure differential.

22. The method of claim 20 , further including:
unsetting the pressure barrier from the wellbore; and
monitoring the pressure in the wellbore below pressure barrier during the unsetting based on third pressure data collected by the pressure gauge, the third pressure data to be accessed via the second acoustic repeater.
