Abstract

A liner assembly ( 100 ) includes a drill string ( 120 ) to drill a borehole ( 105 ) in a formation ( 110 ). The liner assembly further includes a liner assembly releasably coupled to the drill string to move with the drill string in the borehole while the drill string drills, and to be released from the drill string in the borehole after the drill string drills to a depth.

First claim

What is claimed is:

1. A liner assembly, comprising:
a drill string coupled to a drill bit to drill a borehole in a formation;
a latch device, wherein the latch device comprises an anchor and a latch coupling, wherein the latch coupling prevents the anchor from moving axially with respect to the latch coupling when the anchor is at a specific orientation, wherein the latch coupling comprises one or more grooves and one or more pockets on an interior portion of the latch coupling, wherein each of at least one of the one or more grooves and at least one of the one or more pockets comprises a shoulder that prevents the anchor from passing further downhole when the anchor is at the specific orientation, wherein the anchor comprises one or more latch keys, and wherein the one or more latch keys comprise one or more lugs that matingly engage with the one or more pockets to provide force transfer;
a liner assembly releasably coupled to the drill string based, at least in part, on the latch device to move with the drill string in the borehole while the drill string drills, and to be released from the drill string in the borehole after the drill string drills to a depth;
a setting tool coupled to the drill string, wherein the setting tool includes a piston movable in an axial direction with respect to a longitudinal axis of the liner assembly to expand at least a portion of the liner assembly; and
a bottom hole assembly tool coupled between the liner assembly and the drill bit.

2. The liner assembly of claim 1 , wherein the liner assembly comprises a liner hanger coupled to a liner.

3. The liner assembly of claim 2 , wherein the liner hanger is expandable.

4. The liner assembly of claim 1 , wherein the liner assembly comprises a liner hanger that is expandable.

5. The liner assembly of claim 4 , wherein the setting tool comprises a port to allow expansion of the liner hanger based, at least in part, on movement of the piston.

6. The liner assembly of claim 4 , wherein the setting tool allows expansion of the liner hanger based, at least in part, on displacement of a ball or a dart through the drill string.

7. The liner assembly of claim 4 , wherein the setting tool sealingly engages a surface of the liner hanger.

8. The liner assembly of claim 1 , wherein the latch device permits transfer of one or more of an axial force and a rotation force between the drill string and the liner assembly.

9. The liner assembly of claim 1 , further comprising:
a lower latch device, wherein the liner assembly is releasably coupled to the drill string based, at least in part, on the lower latch device; and
wherein the latch device is an upper latch device.

10. The liner assembly of claim 1 , further comprising:
an isolation valve coupled the liner assembly to prevent cement from flowing up the liner assembly.

11. The liner assembly of claim 1 , wherein the drill string comprises:
a drill bit coupled to at least one of a sensor and a drill pipe.

12. The liner assembly of claim 11 , wherein the drill string further comprises:
a reamer coupled to the drill bit to follow the drill bit through the borehole.

13. A method of disposing a liner in a borehole, the method comprising:
releasably coupling a liner assembly to a drill string based, at least in part, on a latch device, the drill string coupled to a drill bit to drill a borehole in a formation;
moving the liner assembly with the drill string in the borehole while the drill string drills to a depth;
moving an anchor of the latch device to a specific orientation;
preventing, by a latch coupling of the latch device, the anchor from moving axially with respect to the latch coupling based on the specific orientation, wherein preventing the anchor from moving axially comprises:
aligning one or more pockets of the latch coupling with one or more latch keys of the anchor, wherein the latch coupling comprises one or more grooves on an interior portion of the latch coupling; and
expanding the one or more latch keys to engage a shoulder of at least one of the one or more latch keys, a shoulder of at least one of the one or more grooves, one or more lugs of the at least one or more latch keys and at least one of the one or more pockets;

releasing the liner assembly from the drill string in the borehole after the drill string drills to the depth;
disposing a bottom hole assembly between the liner assembly and the drill bit; and
setting the liner assembly in the borehole by expanding at least a portion of the liner assembly with a piston of a setting tool, wherein the piston is movable in an axial direction with respect to a longitudinal axis of the liner assembly.

14. The method of disposing a liner in a borehole of claim 13 , wherein the step of setting the liner assembly in the borehole with the setting tool comprises:
displacing an activation device through the drill string.

15. The method of disposing a liner in a borehole of claim 13 , wherein the step of setting the liner assembly in the borehole with the setting tool comprises:
opening a port to allow expansion of the liner hanger based, at least in part, on movement of the piston.

16. The method of disposing a liner in a borehole of claim 13 , wherein the step of setting the liner assembly in the borehole with the setting tool comprises:
expanding an expandable liner hanger of the liner assembly.

17. The method of disposing a liner in a borehole of claim 13 , further comprising:
removing the drill string from the borehole after the liner assembly is set.
