Abstract
A borehole packer includes a shunt tube and a fluid chamber coupled to the shunt tube. The fluid chamber includes a release assembly that releases fluid stored in the fluid chamber into the shunt tube. The fluid includes magnetically responsive particles. The packer also includes one or more magnetic field generators that generate one or more magnetic fields that arrest released fluid within the shunt tube by activating the magnetically responsive particles, thereby plugging the shunt tube.
Claims20
A borehole packer comprising:
- a shunt tube;
- a fluid chamber, coupled to the shunt tube, with a release assembly that releases fluid, including magnetically responsive particles, stored in the fluid chamber into the shunt tube;
- and
- one or more magnetic field generators that generate one or more magnetic fields that arrest released fluid within the shunt tube by aligning the magnetically responsive particles, thereby plugging the shunt tube.
A method of performing a gravel packing operation within a borehole comprising:
- releasing fluid comprising magnetically responsive particles into a shunt tube;
- and
- plugging the shunt tube by activating the magnetically responsive particles to arrest the fluid released into the shunt tube.
