Abstract

A method and system for completing a wellbore in a subsurface formation including first and second sand screens and intermediate tubular joint for gravel transport and/or gravel packing. The assembly provides transport conduits for carrying gravel slurry and packing conduits for gravel slurry placement. The method also includes running the sand screens and intermediately connected joint assembly into the wellbore, and gravel packing not only in the wellbore annulus behind the sand screens, but also behind the intermediate joint assembly to provide a reserve of packing sand behind the intermediate joint assembly to supplement or repack any annular packing sand in the annulus behind the sand screens that may be lost due to sand screen breach, partial collapse of tubular, or other shifting of the gravel pack sand. A wellbore completion apparatus and system is also provided that allows for placement of such gravel reserve.

First claim

What is claimed:

1. A method for completing a wellbore in a subsurface formation, the method comprising: providing a first sand screen assembly having one or more sand control segments; providing a second sand screen assembly having one or more sand control segments; providing a first joint assembly comprising: a non-perforated base pipe, at least one transport conduit extending substantially along the non-perforated base pipe, at least one packing conduit having at least one nozzle configured to release gravel packing slurry into an annular region between the non-perforated base pipe and the subsurface formation; a load sleeve including an inner diameter, with the load sleeve being operably attached to the non-perforated base pipe at or near a first end, the load sleeve having at least one transport conduit and at least one packing conduit; a coupling assembly operably attached to at least a portion of the first end of the non-perforated base pipe, the coupling assembly including a coupling and a manifold region, with the manifold region being located in an annulus exterior to the coupling and is at least partially defined by an exterior surface of the coupling and the manifold region is configured to be in fluid flow communication with the at least one transport conduit and at the least one packing conduit of the load sleeve; and a torque sleeve comprising an inner diameter, with the torque sleeve being operably attached to the non-perforated base pipe at or near the second end, the torque sleeve comprising at least one transport conduit; connecting the first joint assembly in series between the first sand screen assembly and the second sand screen assembly; running the first sand screen assembly, the first joint assembly, and the second sand screen assembly into the wellbore; and injecting a gravel slurry into the wellbore to form a gravel pack around the first and the second sand screen assemblies and at least a portion of the injected gravel slurry introduced into the annular region through the at least one nozzle.

2. The method of claim 1 , further comprising: at least one or more sand control segments comprises; a perforated base pipe having one or more joints, at least one transport conduit extending substantially along the base pipe for transporting gravel packing slurry, a filtering medium radially around the base pipe along a substantial portion of the base pipe so as to form a sand screen, and at least one packing conduit having a nozzle; and releasing gravel packing slurry through the nozzle and into the annular region between the filtering medium and the surrounding subsurface formation.

3. The method of claim 2 , wherein connecting the first sand screen assembly, the first joint assembly, and the second sand screen assembly in series comprises providing that the at least one transport conduit in the first and second sand control segment is in fluid communication with the at least one transport conduit in the first joint assembly, and the first joint assembly is in fluid communication with the second sand screen assembly.

4. The method of claim 2 , wherein at least one of providing the first and second sand screen assemblies comprises providing at least one of a wire-wrapped screen, a slotted liner, a ceramic screen, a membrane screen, an expandable screen, a sintered metal screen, a wire-mesh screen, a shape memory polymer, and a pre-packed solid particle bed.

5. The method of claim 3 , further comprising:
providing a second joint assembly comprising:
a non-perforated base pipe, and
at least one transport conduit extending substantially along the non-perforated base pipe.

6. The method of claim 5 , wherein the second joint assembly does not include a nozzle.

7. The method of claim 3 , further comprising:
providing the at least one transport conduit of the first joint assembly with at least three transport conduits placed concentrically around the non-perforated base pipe, and
providing the at least one packing conduit of the first joint assembly with at least two packing conduits.

8. The method of claim 3 , further comprising injecting the gravel slurry through the nozzle and into the wellbore to deposit gravel packing material around at least a portion of the non-perforated base pipe.

9. The method of claim 1 , wherein providing the joint assembly further comprises:
providing a protective shroud radially around at least a portion of the at least one transport conduit and the at least one packing conduit.

10. The method of claim 9 , wherein the protective shroud is permeable and gravel slurry thereby passes through the protective shroud.

11. A system for completing a wellbore in a subsurface formation, the system comprising:
a first sand screen assembly having one or more sand control segments;
second sand screen assembly having one or more sand control segments;
a first joint assembly comprising;
a non-perforated base pipe,
at least one transport conduit extending substantially along the non-perforated base pipe,
at least one packing conduit having at least one nozzle configured to release gravel packing slurry into an annular region between the non-perforated base pipe and the subsurface formation,
a load sleeve including an inner diameter, with the load sleeve being operably attached to the non-perforated base pipe at or near a first end, the load sleeve having at least one transport conduit and at least one packing conduit;
a coupling assembly operably attached to at least a portion of the first end of the non-perforated base pipe, the coupling assembly including a coupling and a manifold region, with the manifold region being located in an annulus exterior to the coupling and is at least partially defined by an exterior surface of the coupling and the manifold region is configured to be in fluid flow communication with the at least one transport conduit and at the least one packing conduit of the load sleeve; and
a torque sleeve comprising an inner diameter, with the torque sleeve being operably attached to the non-perforated base pipe at or near the second end, the torque sleeve comprising at least one transport conduit;

the first joint assembly connected in series between the first sand screen assembly and the second sand screen assembly;
running the first sand screen assembly, the first joint assembly, and the second sand screen assembly into the wellbore; and
injecting a gravel slurry into the wellbore to form a gravel pack around the first and the second sand screen assemblies and at least a portion of the injected gravel slurry introduced into the annular region through the at least one nozzle.

12. The method of claim 1 , wherein at least one or more sand control segments comprises: a perforated base pipe having one or more joints, at least one transport conduit extending substantially along the base pipe for transporting gravel packing slurry, a filtering medium radially around the base pipe along a substantial portion of the base pipe so as to form a sand screen, and at least one packing conduit having a nozzle configured to release gravel packing slurry into an annular region between the filtering medium and the surrounding subsurface formation.

13. The system of claim 11 , wherein connecting the first sand screen assembly, the first joint assembly, and the second sand screen assembly in series comprises providing that the at least one transport conduit in the first and second sand control segment is in fluid communication with the at least one transport conduit in the first joint assembly, and the first joint assembly is in fluid communication with the second sand screen assembly.
