Abstract
Certain aspects are directed to self-assembling packers that seal an annulus in a downhole wellbore. In one aspect, the packer is formed from a magnetorheological fluid, which may be a carrier fluid formed from a polymer precursor and magnetically responsive particles. The fluid is allowed to be shaped by a magnetic field provided by one or more magnets exerting a radially extending magnetic field from a tubing section used to place the packer.
Claims14
A self-assembling packer for use downhole in a wellbore, comprising:
- a tubing section containing a carrier fluid comprising a polymer precursor and magnetically responsive particles;
- one or more magnets positioned on or within the tubing section, the one or more magnets bordering a space and creating a radially extending magnetic field;
- a component to cause deployment of the carrier fluid into the space to be filled;
- wherein a magnetic field from the one or more magnets is operable for directing the carrier fluid to fill the space,
- wherein the carrier fluid is delivered through a conduit and further comprising a shunt between the conduit and at least one of the one or more magnets.
