Downhole connector orientation for wetmate connectors
Systems and methods are provided to facilitate connection of multiple stage completions. A first completion stage is deployed at a wellbore location. Subsequently, the next completion stage is moved downhole into engagement with the first completion stage. The completion stages each have communication lines that are coupled together downhole via a wetmate connection. Systems and methods for determining an orientation of the communication lines relative to the wellbore are also provided.
1. A downhole completion system, comprising:
an upper completion stage comprising at least one first communication line connector;
a lower completion stage comprising at least one second communication line connector, the at least one first communication line connector configured to couple to the at least one second communication line connector; and
an orientation device configured to help determine and/or control orientation of the at least one second communication line connector relative to a well during or prior to installation, wherein the at least one first communication line connector is configured to be de-mated from the at least one second communication line connector based on an orientation of the at least one first communication line connector relative to the at least one second communication line connector.
2. The downhole completion system of claim 1 , the lower completion stage comprising two second communication line connectors, the orientation device configured to help center the second communication line connectors about the top of the well.
3. The downhole completion system of claim 1 , the orientation device configured to help position the at least one second communication line connector at, near, or about a top of a deviated or horizontal well during installation.
4. The downhole completion system of claim 1 , wherein the upper completion stage comprises a stinger and the lower completion stage comprises a receptacle, and wherein the stinger is configured to engage the receptacle.
5. The downhole completion system of claim 4 , wherein the stinger comprises the at least one first communication line connector and the receptacle comprises the at least one second communication line connector, and engagement of the stinger with the receptacle engages the at least one first communication line connector with the at least one second communication line connector.
6. The downhole completion system of claim 1 , the orientation device comprising accelerometers and/or gyrometers configured to provide data to determine orientation of the second communication line connector.
7. The downhole completion system of claim 6 , the orientation device further comprising a telemetry module configured to transmit the data from the accelerometers and/or the gyrometers to the surface to determine the orientation of the at least one second communication line connector.
8. The downhole completion system of claim 1 , comprising a service string comprising the orientation device, the service string coupled to the lower completion stage for deployment of the lower completion stage in the well.
9. The downhole completion system of claim 1 , the orientation device comprising an index casing coupling incorporated into a casing string deployed in the well, the index casing coupling comprising an orientation feature.
10. The downhole completion system of claim 9 , further comprising a service tool comprising an orientation measurement tool and an orientation key, wherein the orientation measurement tool is configured to provide data to determine an orientation of the index casing coupling when the service tool is run in hole in the casing string and the orientation key of the service tool is engaged with the orientation feature of the index casing coupling.
11. A method of forming a completion in a wellbore, the method comprising:
deploying a lower completion stage in a wellbore, the lower completion stage comprising at least one first communication line connector;
determining an orientation of the at least one first communication line connector with respect to the wellbore;
deploying an upper completion stage in the wellbore, the upper completion stage comprising at least one second communication line connector; and
coupling the at least one first communication line connector and the at least one second communication line connector, wherein the at least one first communication line connector is configured to be de-mated from the at least one second communication line connector based on an orientation of the at least one first communication line connector relative to the at least one second communication line connector.
12. The method of claim 11 , wherein determining the orientation of the at least one first communication line connector comprises transmitting data from an orientation device located on or connected to the lower completion to the surface via an electrical cable or wireless telemetry.
13. The method of claim 11 , wherein the wellbore is a deviated or horizontal wellbore.
14. The method of claim 11 , further comprising rotating the lower completion if needed to orient the at least one first communication line connector in a desired orientation or position.
15. The method of claim 14 , wherein the wellbore is a deviated or horizontal wellbore and the desired orientation or position is at, near, or centered on or about a top of the wellbore.
16. A method of forming a completion in a wellbore, the method comprising:
incorporating a casing orientation device into a casing string;
deploying the casing string in the wellbore;
running a service tool in hole within the casing string;
measuring an orientation of the casing orientation device using an orientation measurement tool of the service tool;
deploying a lower completion stage in the wellbore such that one or more first communication line connectors of the lower completion stage are positioned in a desired orientation based on the orientation of the casing orientation device measured by the service tool;
deploying an upper completion stage in the wellbore, the upper completion stage comprising at least one second communication line connector; and
coupling the first and second communication line connectors.
17. The method of claim 16 , wherein the casing orientation device comprises an orientation feature, the service tool comprises a corresponding orientation feature, and running the service tool in hole comprises engaging the orientation feature of the service tool with the orientation feature of the casing orientation device.
18. The method of claim 17 , wherein measuring the orientation of the casing orientation device comprises determining an orientation of the orientation feature relative to the desired orientation of the one or more first communication line connectors when deployed in the wellbore.
19. The method of claim 18 , further comprising, prior to deploying the lower completion stage in the wellbore, coupling an orientation landing tool comprising an orientation feature to the lower completion stage, and orienting the orientation landing tool and the lower completion stage relative to each other such that when the orientation feature of the orientation landing tool is positioned at the orientation of the orientation feature of the casing orientation device as measured by the service tool, the one or more first communication line connectors are positioned at the desired orientation.
20. The method of claim 16 , wherein the wellbore is a deviated or horizontal wellbore and the desired orientation or position is at, near, or centered on or about a top of the wellbore.
