## Abstract

Systems and methods of the present disclosure relate to protecting a control line as it passes through a junction in a downhole environment. An ETJ deployment tool (ETJDT) comprises a tool body comprising a central bore; at least one first component and at least one second component, each component operable to extend and retract laterally from the tool body, wherein the at least one second component is disposed at an axial distance from the at least one first component along the tool body; a member disposed within the central bore and operable to move forward upon receiving fluid; and a spring disposed axially between a portion of the member and the at least one second component.

## Claims

### Claim 1

A method for passing a control line from a primary wellbore to a secondary wellbore, the method comprising:
disposing an extensible transition joint (ETJ) into the secondary wellbore;
extending the ETJ from the secondary wellbore into the primary wellbore through a window that is disposed between the primary wellbore and the secondary wellbore;
passing a completion string through the ETJ, the completion string comprising a control line; and
retracting the ETJ within the secondary wellbore.

### Claim 2 (depends on 1)

The method of claim 1, further comprising unlocking the ETJ for extension and pushing a movable member of the ETJ to retract the movable member in the secondary wellbore by use of a completion string with one or more control lines or another tubular string or a multi-bore junction assembly.

### Claim 3 (depends on 1)

The method of claim 1, further comprising disposing a multi-bore junction assembly into the primary and secondary wellbores.

### Claim 4

An extensible transition joint (ETJ) for a primary wellbore and a secondary wellbore, comprising:
a first member;
a second member, wherein the first member is movably disposed in the second member to retract into the secondary wellbore from the primary wellbore; and
a lock operable to secure the first member relative to the second member to provide different positions of the first member relative to the second member.

### Claim 5 (depends on 4)

The ETJ of claim 4, wherein the first member is operable to move due to a pull force and/or a fluid pressure, wherein the first member is operable for pull back into the primary wellbore from the secondary wellbore, wherein the first member is operable to extend from a retracted position.

### Claim 6 (depends on 4)

The ETJ of claim 4, further comprising a feature to urge control lines and other equipment to enter the ETJ without causing damage to the ETJ, control lines or other equipment.

### Claim 7 (depends on 4)

The ETJ of claim 4, wherein the ETJ comprises at least one solid or fluted component made of brass, steel, elastomer, or combinations thereof.

### Claim 8 (depends on 4)

The ETJ of claim 4, further comprising ports operable to flush debris.

### Claim 9 (depends on 4)

The ETJ of claim 4, wherein the lock is releasable.

### Claim 10 (depends on 4)

The ETJ of claim 4, further comprising a tapered profile, and wherein the ETJ is sealed.

### Claim 11 (depends on 4)

The ETJ of claim 4, wherein a proximal end of the ETJ is operable to shift the first member from an extended position to a retracted position, upon actuation of a lock release, and wherein the ETJ is operable for re-extension.

### Claim 12

A system for passing a control line from a primary wellbore to a secondary wellbore, the system comprising:
an extensible transition joint (ETJ) comprising:
at least two members;
wherein a first member is operable to retract into a second member, wherein the first and second members of the ETJ are operable to receive the control line passing through the primary and secondary wellbores; and
a tool operable to engage and disengage the ETJ to position the ETJ.

### Claim 13 (depends on 12)

The system of claim 12, wherein the tool comprises a completion deflector running tool (CDRT) operable to extend the ETJ.

### Claim 14 (depends on 12)

The system of claim 12, further comprising a completion string including the control line.

### Claim 15 (depends on 14)

The system of claim 14, further comprising a feature on the completion string to retract the ETJ into the secondary wellbore.

### Claim 16 (depends on 15)

The system of claim 15, wherein the feature includes a shoulder to contact the ETJ.

### Claim 17 (depends on 15)

The system of claim 15, wherein the feature is operable to provide full-bore access to the primary wellbore.

### Claim 18 (depends on 12)

The system of claim 12, wherein the ETJ further comprises a lock operable to secure the first member relative to the second member to provide different positions of the first member relative to the second member.

### Claim 19 (depends on 18)

The system of claim 18, wherein the lock is releasable.

### Claim 20

A method for passing a control line from a primary wellbore to a secondary wellbore, the method comprising:
disposing an extensible transition joint (ETJ) into the secondary wellbore, wherein the ETJ comprises:
a first member; and
a second member, wherein the first member is movably disposed in the second member to retract into the secondary wellbore from the primary wellbore;
extending the ETJ from the secondary wellbore into the primary wellbore through a window that is disposed between the primary wellbore and the secondary wellbore; and
passing a completion string through the ETJ, the completion string comprising a control line.
