Abstract

A service tool and methods for performing subterranean hydrocarbon services in a wellbore. The service tool can include a body that having an aperture formed therethrough. A valve system can be connected to the body. The valve system can selectively form a flow path between a first portion of the aperture and a second portion of the aperture; a flow path between a first flow port formed through a first portion of the body, the aperture, and the outer diameter of the body; and/or a flow path between a channel formed in a portion of the body, a second flow port formed through a second portion of the body, and the second portion of the aperture.

Claims

1. A service tool for performing subterranean hydrocarbon services in a wellbore, comprising:

a body having an aperture formed therethrough;

a valve system connected to the body, wherein a flow path between a first portion of the aperture and a second portion of the aperture is selectively formed by the valve system;

a first flow port formed through a first portion of the body, wherein the valve system selectively forms a flow path between the first portion of the aperture, the first flow port, and an outer diameter of the body;

a channel formed in a portion of the body, wherein the channel is isolated from the first portion of the aperture; and

a second flow port formed through a second portion of the body, wherein the valve system selectively forms a flow path between the second portion of the aperture, the second flow port, and the channel, wherein the valve system forms at least one of the flow paths without longitudinal movement of the body relative to the wellbore.

2. The service tool of claim 1, further comprising a wash pipe connected to the body.

3. The service tool of claim 2, wherein the wash pipe comprises at least one flow port configured to be selectively opened and closed.

4. The service tool of claim 2, wherein the wash pipe is movably connected to the end of the body.

5. The service tool of claim 2, wherein the wash pipe is dissolvable.

6. The service tool of claim 1, wherein the valve system comprises at least one flow control device.

7. The service tool of claim 1, wherein the valve system comprises a valve disposed in the aperture between the first and second flow ports and a flow control device adjacent the flow ports for opening and closing the flow ports.

8. A system for performing at least two subterranean hydrocarbon services in a single trip downhole, comprising:

a service tool disposed within a tubular member forming an annuls therebetween, wherein the service tool comprises;

a body having an aperture formed therethrough;

a valve system connected to the body, wherein a flow path between a first portion of the aperture and a second portion of the aperture is selectively formed by the valve system;

a first flow port formed through a first portion of the body, wherein the valve system selectively forms a flow path between the first portion of the aperture, the first flow port, and an outer diameter of the body;

a channel formed in a portion of the body, wherein the channel is isolated from the first portion of the aperture; and

a second flow port formed through a second portion of the body, wherein the valve system selectively forms a flow path between the second portion of the aperture, the second flow port, and the channel, wherein the valve system forms at least one of the flow paths without longitudinal movement relative to a wellbore; and

wherein the tubular member comprises;

a main body;

a third flow port formed through the main body, wherein a flow path is selectively formed through the third flow port between the annulus and an exterior of the main body without longitudinal movement of the main body; and

a sand screen disposed adjacent the main body.

9. The system of claim 8, further comprising monitoring equipment disposed on the tubular member, the service tool, or both.

10. The system of claim 8, further comprising telemetry equipment configured to provide two way telemetry between the wellbore and the exterior of the wellbore, wherein the telemetry equipment is disposed on at least a portion of the service tool.

11. The system of claim 8, wherein a wash pipe is connected to the body.

12. The system of claim 11, wherein the wash pipe is movably connected to the distal end of the body.

13. The system of claim 11, wherein the wash pipe is dissolvable.

14. A method for performing at least two hydrocarbon services on a wellbore in a single trip downhole, comprising:

locating a service tool within a wellbore adjacent a subterranean formation, the service tool comprising;

a body having an aperture formed therethrough;

a valve system connected to the body, wherein a flow path between a first portion of the aperture and a second portion of the aperture is selectively formed by the valve system;

a first flow port formed through a first portion of the body, wherein the valve system selectively forms a flow path between the first portion of the aperture, the first flow port, and an outer diameter of the body;

a channel formed in a portion of the body, wherein the channel is isolated from the first portion of the aperture; and

a second flow port formed through a second portion of the body, wherein the valve system selectively forms a flow path between the second portion of the aperture, the second flow port, and the channel, wherein the valve system forms at least one of the flow paths without longitudinal movement relative to a wellbore,

wherein during the locating the first and second flow ports are isolated from the aperture of the body by the valve system, and wherein the flow path between the first portion of the body and the second portion of the body is formed by the valve system;

isolating the first portion of the body from the second portion of the body with the valve system without moving the service tool relative to the wellbore;

forming the flow path through the first flow port between the first portion of the aperture of the body and the exterior of the body with the valve system without imparting motion to the service tool relative to the wellbore; and

forming the flow path through the second port between the second portion of the aperture of the body and the channel without moving the service tool relative to the wellbore.

15. The method of claim 14, further comprising disposing the service tool in a tubular member, wherein the tubular member comprises at least one sand screen.

16. The method of claim 15, further comprising providing a gravel slurry from the first portion of the aperture to an annulus about the outer diameter of the tubular member.

17. The method of claim 16, further comprising:

dehydrating the gravel slurry by diverting at least a portion of a fluid portion of the gravel slurry through the sand screen to the inner diameter of the tubular member;

flowing at least a portion of the fluid portion of the gravel slurry from the inner diameter of the tubular member to the second portion of the aperture of the body; and

flowing at least a portion of the fluid portion from the second portion of the aperture of the body to the channel.

18. The method of claim 14, further comprising:

isolating the first flow port and the second flow port from the aperture of the body with the valve system without moving the service tool relative to the wellbore; and

providing fluid communication between the first portion and second portion of the aperture of the body with the valve system without moving the service tool relative to the wellbore.

19. The method of claim 18, further comprising producing hydrocarbons from the wellbore into the aperture of the body.

20. The method of claim 18, further comprising real-time monitoring of the production rate of the hydrocarbons produced from the wellbore.
