Abstract

A system including a plurality of differential pressure actuated tools; a seat receptive to a plug; a first conduit fluidly communicating tubing pressure upstream of the seat to one end of each of the plurality of tools; and a second conduit fluidly communicating tubing pressure downstream of the seat to an opposite end of each of the plurality of tools and method.

Claims (32)

1. A system comprising:

a plurality of differential pressure actuated tools;

a seat receptive to a plug;

a first conduit fluidly communicating tubing pressure upstream of the seat to one end of each of the plurality of tools; and

a second conduit fluidly communicating tubing pressure downstream of the seat to an opposite end of each of the plurality of tools.

2. A system as claimed in claim 1 wherein the plug is a ball.

3. A system as claimed in claim 1 wherein the plug is a dart.

4. A system as claimed in claim 1 wherein the plurality of tools each include a piston chamber.

5. A system as claimed in claim 4 wherein the piston chamber is bifurcated by a piston.

6. A system as claimed in claim 5 wherein the first conduit is fluidly connected to the piston chamber at one side of the piston and the second conduit is connected to the piston chamber at the other side of the piston.

7. A system as claimed in claim 5 wherein the first conduit is fluidly connected to the piston chamber at one side of the piston and the second conduit is connected to the piston chamber at the other side of the piston.

8. A system as claimed in claim 4 wherein the piston chamber is bifurcated by a piston.

9. A system as claimed in claim 1 wherein one of the first and second conduit is a pathway.

10. A system as claimed in claim 1 wherein one of the first and second conduit is a control line.

11. A system as claimed in claim 1 wherein the plurality of tools include one or more valves.

12. A system as claimed in claim 1 wherein the plurality of tools include one or more sliding sleeves.

13. A method for actuating a plurality of tools in a downhole environment comprising:

deploying a plug into a borehole comprising the system claimed in claim 1 ;

landing the plug in the seat;

creating a differential pressure across each of the plurality of tools; and

actuating the plurality of tools with the differential pressure.

14. A system as claimed in claim 1 wherein the plug is a ball.

15. A system as claimed in claim 1 wherein the plug is a dart.

16. A system as claimed in claim 1 wherein the plurality of tools each include a piston chamber.

17. A system as claimed in claim 1 wherein one of the first and second conduit is a control line.

18. A system as claimed in claim 1 wherein the plurality of tools include one or more valves.

19. A system as claimed in claim 1 wherein the plurality of tools include one or more sliding sleeves.

20. A system comprising:

a plurality of differential pressure actuated tools;

a seat receptive to a plug;

a first conduit fluidly communicating tubing pressure upstream of the seat to one end of each of the plurality of tools; and

a second conduit fluidly communicating tubing pressure downstream of the seat to an opposite end of each of the plurality of tools, the system configured to be actuated by landing the plug into the seat to create a differential pressure across each of the plurality of tools.
