Abstract
An assembly for creating a packer can include a downhole tool positionable within a wellbore. The downhole tool can include an outflow control device that includes a substantially circumferential slot, a port in the slot for receiving a sealant from a reservoir, and a flow restriction device that can be positioned between the substantially circumferential slot and an annulus of the wellbore. The flow restriction device can create a pressure difference between the substantially circumferential slot and the annulus of the wellbore.
Claims20
An assembly comprising:
- a downhole tool positionable within a wellbore comprising:
- an outer surface that defines an outer circumference of the downhole tool, and
- an outflow control device comprising:
- a slot extending through the outer surface of the downhole tool, the slot extending around substantially the entire outer circumference of the downhole tool;
- a port extending through a surface that defines the slot for receiving a sealant from a reservoir;
- and
- a flow restriction device positioned between the slot and an annulus of the wellbore for creating a pressure difference between the slot and the annulus of the wellbore.
An assembly comprising:
- a downhole tool positionable within a wellbore, the downhole tool including a tubing string including an outflow control device comprising:
- a slot extending through an outer surface of the tubing string, the slot extending substantially entirely around an outer circumference of the tubing string;
- a port extending through a surface that defines the slot for receiving a sealant;
- and
- a flow restriction device positioned above the slot for creating a pressure difference between the slot and an annulus of the wellbore;
- a reservoir for containing the sealant;
- a delivery conduit that couples the reservoir to the port;
- and
- an ejection device for ejecting the sealant from the reservoir into the delivery conduit.
An assembly, comprising:
- a downhole tool including a flow control device comprising:
- a slot extending partially through an outer surface of the downhole tool, the slot extending at least substantially entirely around an outer circumference of the downhole tool;
- a port extending through a surface that defines the slot for receiving a sealant;
- and
- a flow restriction device positioned between an inner area of the slot and an outer area of the slot for creating a pressure difference between the inner area of the slot and the outer area of the slot;
- and
- a reservoir for containing the sealant.
