Patent
·
OSTI ID:6606468
A permanent thermal packer is disclosed for sealing the annulus between an injection tubing string and a well casing. The packer is thermal cement and is placed from within the injection tubing string to seal a substantial portion of the annulus above the injection zone. The packer provides a means for sealing the annulus above the injection zone thus permitting insulating material to be placed in the annulus above the packer with the expectation that it will not be damaged by well bore fluids.
