Abstract

A method of installing multi-trip completions in a borehole. The method includes interfacing a health monitoring system with a first section of the multi-trip completions, the health monitoring system configured to engage with at least one of a first control line and first equipment of the first section. Running the health monitoring system and the first section downhole to a selected position within the borehole; storing information about a health of the at least one of the first control line and first equipment of the first section within the health monitoring system. Removing the health monitoring system from the borehole while leaving the first section within the borehole; accessing the information from the health monitoring system; and, determining, based on the information, whether or not to run a second section having a second control line into the borehole. The second control line configured to connect with the first control line.

First claim

What is claimed is:

1. A method of installing multi-trip completions in a borehole, the method comprising:
interfacing a health monitoring system with a first section of the multi-trip completions, the health monitoring system configured to engage with a equipment including a first control line and a device of the first section;
running the health monitoring system and the first section into the borehole in a downhole direction to a selected position within the borehole;
storing information about a health of at least one of the first control line and the device of the first section within the health monitoring system;
removing the health monitoring system from the borehole while leaving the first section within the borehole;
accessing the information from the health monitoring system; and,
determining, based on the information, whether or not to run a second section having a second control line into the borehole, the second control line configured to connect with the first control line.

2. The method of claim 1 , wherein interfacing a health monitoring system with a first section includes connecting the first section to a running tool, the health monitoring system integrated with the running tool.

3. The method of claim 2 , wherein interfacing a health monitoring system with a first section further includes connecting the running tool to a wetmate connector on the first section.

4. The method of claim 2 , wherein running the health monitoring system and the first section into the borehole in a downhole direction to a selected position within the borehole includes running the health monitoring system, running tool, and first section downhole together to the selected position.

5. The method of claim 1 , wherein removing the health monitoring system from the borehole includes bringing the health monitoring system to a surface location of the borehole, and accessing the information at the surface location.

6. The method of claim 1 , wherein storing information about a health of the at least one of the first control line and the device of the first section within the health monitoring system includes storing monitored information from the at least one of the first control line and the device in the first section, and further comprising analyzing the monitored information to determine if the at least one of the first control line and the device is operatively functional or damaged.

7. The method of claim 1 , further comprising using the health monitoring system to test the at least one of the first control line and the device of the first section, and storing information about a health of the at least one of the first control line and the device of the first section within the health monitoring system includes storing information about whether the at least one of the first control line and the device is operatively functional or damaged.

8. The method of claim 1 , wherein determining, based on the information, whether or not to run a second section having a second control line into the borehole, includes determining not to run the second section if the at least one of the first control line and the device is damaged and determining to run the second section downhole to the first section if the at least one of the first control line and the device is operatively functional.

9. A multi-trip completions system comprising:
a first section having at least one of a first control line and a device;
a health monitoring system configured to interface with the first section and to store information regarding a health of the at least one of the first control line and the device, the health monitoring system independent from surface control; and,
a second section having at least one second control line, the second section configured to connect with the first section after the health monitoring system is disconnected from the first section.

10. The multi-trip completions system of claim 9 , wherein information regarding a health of the at least one first control line and the device includes information regarding if the at least one of the first control line and the device is damaged or operatively functional.

11. The multi-trip completions system of claim 9 , wherein the health monitoring system further includes a battery.

12. The multi-trip completions system of claim 9 , wherein the health monitoring system further includes at least one sensor configured to detect at least one of temperature and pressure.

13. The multi-trip completions system of claim 9 , further comprising a first wetmate connector connected to the first section, a second wetmate connector connected to the second section, the first and second wetmate connectors configured to connect the at least one first control line to the at least one second control line.

14. The multi-trip completions system of claim 9 , further comprising a running tool, the health monitoring system connected to the running tool, the running tool configured to deliver the first section downhole with the health monitoring system.

15. The multi-trip completions system of claim 14 , wherein the health monitoring system is connected to the at least one first control line through the running tool via a control line connection.

16. The multi-trip completions system of claim 14 , further comprising a first wetmate connector connected to the first section, a second wetmate connector connected to the second section, the first and second wetmate connectors configured to connect the at least one first control line to the at least one second control line, and a third wetmate connector connected to the running tool, the third wetmate connector configured to connect to the first wetmate connector and configured to connect the at least one first control line to the health monitoring system.

17. The multi-trip completions system of claim 9 , wherein the health monitoring system is configured to be internal to the first section.

18. The multi-trip completions system of claim 9 , further comprising a control system at a surface location of a borehole in which the first section is disposed, wherein the health monitoring system is disconnected from the control system when disposed in the borehole with the first section, and the at least one first control line is in communication with the control system when the at least one first control line is connected to the at least one second control line.

19. The multi-trip completions system of claim 9 , wherein the first section includes a gravel pack assembly.

20. The multi-trip completions system of claim 9 , further comprising a test signal deliverable by the health monitoring system to the at least one of the first control line and the device.
