Abstract

A system for use with a well can include a perforating assembly with at least one perforator, the perforating assembly conveyed through a wellbore with fluid flow through the wellbore, and plugging devices spaced apart from the perforating assembly in the wellbore, the plugging devices conveyed through the wellbore with the fluid flow. A method of deploying plugging devices in a wellbore can include conveying a perforating assembly including a dispensing tool through the wellbore, the dispensing tool including a container, and then releasing the plugging devices from the container into the wellbore at a downhole location. Another method of deploying plugging devices in a wellbore can include conveying the plugging devices through the wellbore with fluid flow through the wellbore, and conveying a perforating assembly through the wellbore while the plugging devices are being conveyed through the wellbore.

Claims

1. A system for use with a subterranean well, the system comprising:

a perforating assembly including at least one perforator, the perforating assembly conveyed through a wellbore with fluid flow through the wellbore, wherein the wellbore is free of any production string; and

plugging devices spaced apart from the perforating assembly in the wellbore, the plugging devices conveyed through the wellbore with the fluid flow,

wherein the plugging devices are released from a container of the perforating assembly,

wherein the perforating assembly further includes an actuator configured to release the plugging devices from the container, and

wherein each of the plugging devices comprises a body that is configured to engage an opening in a wall of a tubular string in the wellbore to substantially block fluid from flowing outward through the opening the body can engage the opening but is too large to pass through the opening and, extending outwardly from the body, at least one of the group consisting of lines and fibers.

2. The system of claim 1, wherein the at least one of the group consisting of lines and fibers has a lateral dimension substantially less than a size of the body.

3. The system of claim 1, wherein the body of each of the plugging devices comprises a knot.

4. A method of deploying plugging devices in a wellbore, the method comprising:

conveying a perforating assembly including a dispensing tool through the wellbore with fluid flow through the wellbore, the dispensing tool including a container, and the wellbore not including a production string; and

then releasing the plugging devices from the container into the wellbore at a downhole location,

wherein each of the plugging devices comprises a body that is configured to engage an opening in a wall of a tubular string in the wellbore to substantially block fluid from flowing outward through the opening, the body can engage the opening but is too large to pass through the opening and, extending outwardly from the body, at least one of the group consisting of lines and fibers.

5. The method of claim 4, wherein the at least one of the group consisting of lines and fibers has a lateral dimension substantially less than a size of the body.

6. The method of claim 4, wherein the body of each of the plugging devices comprises a knot.

7. A method of deploying plugging devices in a wellbore, the method comprising:

releasing the plugging devices from a dispensing tool into the wellbore;

conveying the plugging devices through the wellbore with fluid flow through the wellbore; and

prior to the plugging devices engaging respective openings in the wellbore, conveying a perforating assembly through the wellbore while the plugging devices are being conveyed through the wellbore,

wherein each of the plugging devices comprises a body and, extending outwardly from the body, at least one of the group consisting of lines and fibers.

8. The method of claim 7, wherein the at least one of the group consisting of lines and fibers has a lateral dimension substantially less than a size of the body.

9. The method of claim 7, wherein the body of each of the plugging devices comprises a knot.
