Abstract

A method can include conveying a dispensing tool through a wellbore, the dispensing tool including an enclosure containing plugging devices, and then opening the enclosure by cutting a material of the enclosure, thereby releasing the plugging devices from the enclosure into the wellbore at a downhole location. A dispensing tool can include a container having an enclosure therein, the enclosure including a flexible material that contains the plugging devices, and an end of the enclosure being secured to a member displaceable by an actuator. The enclosure material is cut in response to displacement of the member by the actuator. A plugging device can include at least one body configured to engage an opening in the well and block fluid flow through the opening, and multiple fibers including staple fibers or filaments formed into yarn.

First claim

What is claimed is:

1. A method of deploying plugging devices in a wellbore, the method comprising:
conveying a dispensing tool through the wellbore, the dispensing tool including an enclosure containing the plugging devices; and
then
pulling one end of the enclosure relative to an opposite end of the enclosure, thereby tearing open the enclosure and releasing the plugging devices from the enclosure into the wellbore at a downhole location.

2. The method of claim 1 , in which the pulling comprises displacing a member of a valve.

3. The method of claim 2 , in which the valve member comprises an inner sleeve that selectively blocks flow through at least one port of the valve.

4. The method of claim 1 , in which the releasing comprises producing fluid flow through a flow passage in communication with an interior of the enclosure.

5. The method of claim 4 , in which the pulling comprises opening a valve, thereby permitting the fluid flow from an exterior of the dispensing tool to the flow passage.

6. The method of claim 1 , in which the pulling comprises operating an actuator of the dispensing tool.

7. The method of claim 1 , further comprising connecting the dispensing tool and a perforator in a perforating assembly.
