Abstract

A liner deployment assembly (LDA) for use in a wellbore includes: a crossover tool. The crossover tool includes: a seal for engaging a tubular string cemented into the wellbore; a tubular housing carrying the seal and having bypass ports straddling the seal; a mandrel having a bore therethrough and a port in fluid communication with the mandrel bore, the mandrel movable relative to the housing between a bore position where the mandrel port is isolated from the bypass ports and a bypass position where the mandrel port is aligned with one of the bypass ports; a bypass chamber formed between the housing and the mandrel and extending above and below the seal; and a control module. The control module includes: an electronics package; and an actuator in communication with the electronics package and operable to move the mandrel between the positions.

First claim

The invention claimed is:

1. A liner deployment assembly (LDA) for use in a wellbore, comprising:
a crossover tool, comprising:
a seal for engaging a tubular string cemented into the wellbore;
a tubular housing carrying the seal and having bypass ports straddling the seal and formed through a wall of the tubular housing;
a mandrel having a bore therethrough and a port in fluid communication with the mandrel bore, the mandrel movable relative to the housing between a bore position where the mandrel port is isolated from the bypass ports and a bypass position where the mandrel port is aligned with one of the bypass ports;
a bypass chamber formed between the housing and the mandrel and extending above and below the seal; and
a control module, comprising:
an electronics package; and
an actuator in communication with the electronics package and operable to move the mandrel between the positions;

wherein the mandrel port is radially aligned with the one of the bypass ports in the bypass position.

2. The LDA of claim 1 , wherein:
the crossover tool further comprises:
a piston connected to the mandrel; and
an actuation chamber formed between the piston and the housing and having a pusher portion and a puller portion, and

the LDA further comprises first and second hydraulic conduits connecting the respective actuation chamber portions to the actuator.

3. The LDA of claim 2 , wherein:
the LDA further comprises a circulation sub,
the circulation sub comprises a circulation housing; a circulation valve; a bore valve; a circulation piston; and an actuation chamber formed between the circulation piston and the circulation housing and having an opener portion and a closer portion, and
the LDA further comprises third and fourth hydraulic conduits connecting the respective opener and closer chamber portions to the actuator.

4. The LDA of claim 3 , wherein:
the circulation sub further comprises a circulation bore formed therethrough,
the circulation housing is connected to the crossover housing and the control module and has a circulation port formed through a wall thereof,
the circulation valve comprises a valve sleeve having a port formed through a wall thereof and movable relative to the circulation housing between an open position having the circulation port aligned with the valve sleeve port and a closed position having the valve sleeve wall covering the circulation port,
the circulation piston is connected to the valve sleeve, and
the bore valve comprises:
a valve member connected to the valve sleeve below the valve sleeve port for opening and closing the circulation bore; and
a cam for opening the valve member when the valve sleeve moves from the open position to the closed position and for closing the valve member when the valve sleeve moves from the closed position to the open position.

5. The LDA of claim 1 , wherein the seal is a rotary seal, comprising:
a bearing;
a sleeve supported from the housing by the bearing;
a gland connected to the seal sleeve; and
a directional seal connected to the gland.

6. The LDA of claim 5 , wherein:
the directional seal has a first orientation, and
the rotary seal further comprises a second directional seal having a second orientation opposite to the first orientation.

7. The LDA of claim 1 , wherein the control module further comprises:
an antenna housing having an antenna bore formed therethrough; and
an inner antenna disposed in the antenna housing adjacent to the antenna bore for receiving a signal from a radio frequency identification (RFID) tag pumped through the antenna bore.

8. The LDA of claim 1 , further comprising:
a setting tool connected to the crossover tool and hydraulically operable to set a liner hanger; and
a liner isolation valve (LIV) connected to the setting tool for closing of a bore of the LDA to operate the setting tool and comprising:
a valve module operable between a check or closed position for operating the setting tool and an open position; and
a valve control module comprising:
an antenna housing having an antenna bore formed therethrough;
an inner antenna disposed in the antenna housing adjacent to the antenna bore for receiving a signal from a radio frequency identification (RFID) tag pumped through the antenna bore;
an electronics package in communication with the antenna and comprising a pressure sensor in fluid communication with the antenna bore; and
an actuator in communication with the electronics package and operable to actuate the valve module between the positions.

9. The LDA of claim 8 , wherein:
the valve module is operable between the check position and the open position, and
the valve module comprises a check valve operable to allow fluid flow from the LIV to the setting tool and prevent reverse fluid flow from the setting tool to the LIV and a stem operable to prop open the check valve.

10. The LDA of claim 8 , wherein:
the valve module comprises a flapper,
the open position is an upwardly open position of the flapper, and
the flapper is further operable to a downwardly open position.

11. The LDA of claim 8 , further comprising:
a stinger connected to the LIV for propping open a float collar of a liner string; and
a latch for longitudinally and torsionally connecting the liner string to the LDA.

12. The LDA of claim 1 , wherein:
the mandrel is disposed in the tubular housing;
the one of the bypass ports is in fluid communication with an annulus between the wellbore and the tubular housing below the seal; and
another of the bypass ports is in fluid communication with the annulus above the seal.

13. The LDA of claim 1 , wherein the bypass ports are formed radially through the wall of the tubular housing.

14. The LDA of claim 1 , further comprising a circulation sub, the circulation sub comprises:
a circulation housing;
a circulation valve;
a bore valve;
a circulation piston; and
an actuation chamber formed between the circulation piston and the circulation housing and having an opener portion and a closer portion.

15. The LDA of claim 14 , the circulation sub further comprises a circulation bore formed therethrough, and
the circulation housing is connected to the crossover housing and the control module and has a circulation port formed through a wall thereof.

16. The LDA of claim 15 , wherein the circulation valve comprises:
a valve sleeve having a port formed through a wall thereof and movable relative to the circulation housing between an open position having the circulation port aligned with the valve sleeve port and a closed position having the valve sleeve wall covering the circulation port,
wherein the circulation piston is connected to the valve sleeve, and
wherein the bore valve comprises:
a valve member connected to the valve sleeve below the valve sleeve port for opening and closing the circulation bore; and

a cam for opening the valve member when the valve sleeve moves from the open position to the closed position and for closing the valve member when the valve sleeve moves from the closed position to the open position.

17. A liner deployment assembly (LDA) for use in a wellbore, comprising:
a crossover tool, comprising:
a seal for engaging a tubular string cemented into the wellbore;
a tubular housing carrying the seal and having bypass ports straddling the seal;
a mandrel having a bore therethrough and a port in fluid communication with the mandrel bore, the mandrel movable relative to the housing between a bore position where the mandrel port is isolated from the bypass ports a
