## Abstract

A method of completing a wellbore system that includes a main wellbore and a lateral wellbore intersecting the main wellbore at a junction is disclosed, wherein in one embodiment the method includes placing a first outer assembly below the junction in the main wellbore and placing a second outer assembly below the junction in the lateral wellbore; placing a first inner assembly in the second outer assembly with a top end thereof below the junction, the top end of the first inner assembly including a first wet connect associated with at least one link in the first inner assembly; and connecting a second wet connect of a string with the first wet connect with a top end of the string having a third wet connect corresponding to the at least one link above the junction in the main wellbore.

## Claims

### Claim 1

A method of completing a first wellbore and a second wellbore intersecting the first wellbore at a junction; the method comprising:
placing a first outer assembly below the junction in the first wellbore and placing a second outer assembly below the junction in the second wellbore;
placing a first inner assembly in the second outer assembly with a top end thereof below the junction, the top end of the first inner assembly including a first wet connect associated with at least one link in the first inner assembly; and
connecting a second wet connect of a string with the first wet connection with a top end of the string having a third wet connect corresponding to the at least one link above the junction in the first wellbore.

### Claim 2 (depends on 1)

The method of claim 1 further comprising:
placing a second inner string in the first outer string; and
connecting a fourth wet connect to the third wet connect to provide a continuous link from the first inner assembly to a surface location.

### Claim 3 (depends on 1)

The method of claim 1, wherein the first inner string includes at least one sensor for determining a parameter of interest relating to a downhole operation in the second wellbore.

### Claim 4 (depends on 3)

The method of claim 3, wherein the at least one link includes one of: an electrical conductor; a fiber optic link; and a hydraulic line.

### Claim 5 (depends on 3)

The method of claim 3, wherein the parameter of interest is selected from a group consisting of: pressure; temperature, flow rate; vibration; abrasion and corrosion.

### Claim 6 (depends on 2)

The method of claim 2, wherein the inner string includes at least one sensor coupled to the at least one link.

### Claim 7 (depends on 1)

The method of claim 1 further comprising fracturing a zone in one of the first wellbore and the second wellbore before placing the first inner string in the second wellbore.

### Claim 8 (depends on 1)

The method of claim 1, wherein the junction is an open hole junction extending from a first selected location below the junction in the second wellbore to a second selected location above the junction in the first wellbore.

### Claim 9 (depends on 6)

The method of claim 6 further comprising monitoring an operation of the second wellbore in response to measurements provided by the at least one sensor in the second wellbore.

### Claim 10 (depends on 9)

The method of claim 9, wherein the measurement is selected from a group consisting of: temperature; pressure; and flow rate; vibration; abrasion; and corrosion.

### Claim 11

A wellbore system having a lateral wellbore formed from a main wellbore at a junction thereof, the wellbore system comprising:
an outer assembly in the lateral wellbore with a top end thereof below the junction in the lateral wellbore and an inner assembly in the outer assembly in the lateral wellbore, wherein the inner assembly includes a top end that has a first wet connect corresponding to a link in the inner assembly below the junction; and
a string having a second wet connect at a lower end connected to the first wet connect in the lateral wellbore and further having a third wet connect in the main wellbore above the junction.

### Claim 12 (depends on 11)

The wellbore system of claim 11 further comprising a string extending from a surface location having a fourth wet connect connected to the third wet connect to provide a continuous link from the lateral wellbore to the surface.

### Claim 13 (depends on 12)

The wellbore system of claim 12, wherein the inner string in the lateral wellbore includes a sensor for determining a parameter of interest relating to the lateral wellbore.

### Claim 14 (depends on 13)

The wellbore system of claim 13, wherein the link includes one of: an electrical conductor; a fiber optic link; and a hydraulic line.

### Claim 15 (depends on 13)

The wellbore system of claim 13, wherein the parameter of interest is selected from a group consisting of: pressure; temperature, flow rate; vibration; abrasion; and corrosion.

### Claim 16 (depends on 12)

The wellbore system of claim 12 further comprising a sensor in the second wellbore for providing information relating to a parameter of interest in the first wellbore.

### Claim 17 (depends on 12)

The wellbore system of claim 12 further comprising a controller that controls a device in the second wellbore via the continuous link.

### Claim 18 (depends on 11)

The wellbore system of claim 11, wherein the junction is an open hole junction extending from a first location below the junction in the second wellbore to a second location above the junction in the first wellbore.

### Claim 19

A method of completing a main wellbore and a lateral wellbore intersecting the main wellbore at a junction, the method comprising:
providing a first wet mate assembly below the junction, the first wet mate assembly including a first wet connect coupled to a first link in the lateral wellbore and a second wet connect connected to the first wet connect; and
providing a second wet mate assembly in the main wellbore that includes a third wet connect coupled to the second wet connect via a second link and a fourth wet connect connected to the third wet connect.
