Abstract
A system and method is provided for creating a packer in a wellbore for utilization in a variety of wellbore applications. The packer is created by flowing a slurry of particular matter and liquid to a desired location. At the desired location, the slurry is dehydrated, leaving deposition of the particulate matter to create a packer.
Claims49
A method of creating a packer in a wellbore, comprising:
- deploying a screen downhole via a tubing;
- flowing a slurry of liquid and particulate matter from a wellhead downwardly to the screen through an annulus surrounding at least the tubing;
- and
- generating a packer by passing the liquid through the screen while substantially blocking movement of the particulate matter through the screen.
1 more element
A method of creating a packer in a wellbore, comprising:
- supplying a slurry to a dehydration device located downhole, via a single supply flow path;
- depositing particulate matter on an external side of the dehydration device to generate a packer;
- removing liquid along a single removal flow path;
- conducting a well related procedure;
- moving the dehydration device to another wellbore location without removing the dehydration device from the wellbore;
- and
- repeating the process of generating a packer and conducting a well related procedure.
4 more elements
A method of creating a packer in wellbore, comprising:
- deploying a wellbore assembly in a wellbore, the wellbore extending from an upper surface;
- flowing a slurry from the upper surface through an annulus surrounding the wellbore assembly to a desired location in wellbore;
- and
- dehydrating the slurry at the desired location.
1 more element
A system for creating a packer in a wellbore, comprising:
- a wellbore assembly deployed in a wellbore, the wellbore assembly creating an annulus along its exterior, the annulus serving as a first flow path from a surface location to a downhole location, the wellbore assembly also defining a second flow path along its interior, wherein the wellbore assembly comprises a dehydration device positioned to create a packer when a slurry of particular matter and liquid is directed along the first flow path such that the liquid moves through the dehydration device to the second flow path while the particulate matter is deposited to form the packer.
