  • Patent number: 4385664
    Abstract: A subsurface wellbore completion assembly for a cased well is disclosed. The assembly includes thermal cup packers which may be set at a subsurface location along the well above a hot fluid injection zone. The assembly is run into the well on a tubing string and, at the desired depth, the assembly is converted to operating condition where the packers and slips are set. The apparatus may be reassembled to running condition for withdrawal from the well or the packers may be drilled-over to permit washover in the well.
