## Abstract

A hanger system including an expandable liner, an expandable first slip subsystem disposed about the liner, an expandable second slip subsystem disposed about the liner, a seal disposed about the liner and between the first slip subsystem and the second slip subsystem, and an expandable lock ring disposed about the liner and against one of the first slip subsystem or the second slip subsystem. A method for lining a borehole including running a liner system into a borehole, landing the liner system in a liner hanger, expanding the first slip subsystem simultaneously with a portion of the liner, expanding the second slip subsystem simultaneously with another portion of the liner, and sealing the liner to the liner hanger between the first slip subsystem and the second slip subsystem with the seal. A borehole system including a borehole in a subsurface formation, a casing in the borehole, and a liner system.

## Claims

### Claim 1

A liner hanger system comprising:
an expandable liner;
an expandable first slip subsystem disposed about the liner;
an expandable second slip subsystem disposed about the liner;
a seal disposed about the liner and between the first slip subsystem and the second slip subsystem; and
an expandable lock ring disposed about the liner and against one of the first slip subsystem or the second slip subsystem, wherein the lock ring compresses the first slip subsystem, second slip subsystem and seal against one another for run in.

### Claim 2 (depends on 1)

The system as claimed in claim 1 further comprising an expandable anchor having a wicker on an outside surface thereof.

### Claim 3 (depends on 2)

The system as claimed in claim 2 wherein the wicker is a plurality of wickers.

### Claim 4 (depends on 2)

The system as claimed in claim 2 wherein the wicker is unhardened.

### Claim 5 (depends on 2)

The system as claimed in claim 2 wherein the anchor includes a polished bore therein.

### Claim 6 (depends on 1)

The system as claimed in claim 1 wherein the lock ring is disposed about the liner adjacent one of the first slip subsystem and the second slip subsystem.

### Claim 7 (depends on 1)

The system as claimed in claim 1 wherein the lock ring includes a wicker on an exterior surface thereof.

### Claim 8 (depends on 7)

The system as claimed in claim 7 wherein the wicker is a plurality of wickers.

### Claim 9 (depends on 7)

The system as claimed in claim 7 wherein the wicker is hardened.

### Claim 10 (depends on 1)

A method for lining a borehole comprising:
running a liner hanger system as claimed in claim 1 into a borehole;
landing the liner hanger system in the borehole;
expanding the first slip subsystem simultaneously with a portion of the liner;
expanding the second slip subsystem simultaneously with another portion of the liner; and
sealing the liner to the liner hanger between the first slip subsystem and the second slip subsystem with the seal.

### Claim 11 (depends on 10)

The method as claimed in claim 10 further comprising expanding an anchor of the liner system.

### Claim 12 (depends on 11)

The method as claimed in claim 11 wherein the expanding is by swaging.

### Claim 13 (depends on 11)

The method as claimed in claim 11 wherein wickers of the anchor are driven into a parent casing.

### Claim 14 (depends on 11)

The method as claimed in claim 11 wherein the anchor is expanded without splitting thereof.

### Claim 15 (depends on 10)

The method as claimed in claim 10 wherein the wickers of the anchor arrest longitudinal movement of the liner while expanding thereby causing the first and second slip subsystems to set without axial movement relative to the hanger.

### Claim 16 (depends on 10)

The method as claimed in claim 10 further comprising expanding the lock ring simultaneously with another portion of the liner.

### Claim 17 (depends on 16)

The method as claimed in claim 16 further including splitting the lock ring due to expansion thereof.

### Claim 18 (depends on 16)

The method as claimed in claim 16 further comprising driving a wicker on an exterior surface of the lock ring into the hanger to arrest longitudinal movement of the liner relative to the hanger.

### Claim 19 (depends on 1)

A borehole system comprising:
a borehole in a subsurface formation;
a casing in the borehole; and
a liner hanger system as claimed in claim 1 disposed within the casing.
