Abstract

A ported tubular is provided for use in casing a wellbore, to permit selective access to the adjacent formation during completion operations. A system and method for completing a wellbore using the ported tubular are also provided. Ports within the wellbore casing may be opened, isolated, or otherwise accessed to deliver treatment to the formation through the ports.

Claims

1. A method for delivering treatment fluid to a formation intersected by a wellbore, the method comprising the steps of:

lining the wellbore with tubing, the liner tubing comprising at least a first ported segment and a second ported segment each ported segment having at least one lateral opening through the liner tubing;

deploying a tool assembly downhole in the lined wellbore on tubing string, the tool assembly comprising an abrasive fluid perforation device and a sealing member;

locating the tool assembly at a depth generally corresponding to the first ported segment;

setting the sealing member against the liner tubing below the first ported segment;

delivering treatment fluid to the first ported segment;

unsetting the sealing member from the liner tubing;

locating the tool assembly at a depth generally corresponding to the second ported segment;

resetting the sealing member against the liner tubing below the second ported segment; and

delivering treatment fluid to the second ported segment.

2. The method recited in claim 1, wherein the step of locating the tool assembly comprises the step of engaging a casing collar locator on the tool assembly in at least one casing collar in the liner tubing.

3. The method recited in claim 1, wherein the lateral openings are ports provided in the liner tubing prior to lining the wellbore.

4. The method recited in claim 1, wherein the tool assembly further comprises a straddle isolation device comprising first and second sealing members, and a treatment aperture between the first and second sealing members, the treatment aperture continuous with the tubing string for delivery of treatment fluid from the tubing string to the formation through the port.

5. The method recited in claim 4, wherein the first and second sealing members are inflatable sealing elements.

6. The method recited in claim 4, wherein the first and second sealing members are compressible sealing elements.

7. The method recited in claim 4, wherein the first and second sealing members are cup seals.

8. The method recited in claim 1, wherein the sealing member is selected from the group consisting of mechanically-set packers, inflatable packers, and bridge plugs.

9. The method recited in claim 1, wherein the first ported segment comprises a closure over the lateral opening, and wherein the method further comprises the step of moving the closure from over the lateral opening.

10. The method recited in claim 9, wherein the closure comprises a sleeve slidingly disposed within the tubular segment, and wherein the method further comprises the step of sliding the sleeve to open the lateral opening.

11. The method recited in claim 10, wherein the step of sliding the sleeve comprises the application of hydraulic pressure to the sleeve.

12. The method recited in claim 10, wherein the step of sliding the sleeve comprises application of mechanical force to the sleeve by the tool assembly.

13. The method recited in claim 10, wherein the step of sliding the sleeve comprises application of mechanical force and hydraulic pressure to the sleeve.

14. The method recited in claim 1, wherein the tubing string is coiled tubing.

15. The method recited in claim 1, further comprising the step of jetting perforations in the liner tubing.

16. The method recited in claim 15, wherein the step of jetting perforations in the liner tubing comprises delivering abrasive fluid through the tubing string to jet nozzles in the abrasive fluid perforation device.

17. The method recited in claim 1, further comprising the steps of:

closing an equalization valve in the tool assembly to provide a dead leg; and

monitoring the bottom hole pressure while delivering treatment fluid.

18. A method for hydraulically fracturing a formation intersected by a wellbore comprising the steps of:

lining the wellbore with tubing, the liner tubing comprising at least one ported segment, the ported segment having at least one lateral opening through the liner tubing covered by a closure;

deploying a tool assembly downhole in the lined wellbore on tubing string, the tool assembly comprising an abrasive fluid perforation device and a sealing member;

locating the tool assembly at a depth at which the sealing member is adjacent the closure;

setting the sealing member against the closure;

moving the tool assembly;

determining whether the closure has moved from a closed position;

delivering pressured fluid through the ported segment if the closure has moved from the closed position; and

jetting perforations in the liner tubing with the abrasive fluid perforation device and delivering pressurized fluid to the jetted perforations if the closure has not moved from the closed position.
