  • Patent number: 12091947
    Abstract: A method and an apparatus for sealing perforations or cracks found in an oil well casing. The apparatus includes a hydraulic cylinder with an oil supply section at one end and a rod at another end, a cylindrical liner at least a portion of which is a malleable metal and a receiver; and a frusto-conical wedge being disposed at a lower end of the liner and fixedly connected to the rod. The method includes lowering the apparatus into the well casing and increasing hydraulic pressure to the hydraulic cylinder sufficient to pull the frusto-conical shaped wedge into the liner providing sufficient lateral force to force sufficient liner material into the perforations or cracks of the well casing to seal the well casing wall.

  • Patent number: 11933134
    Abstract: A method of sealing a well having a casing wall comprises transporting a camera into the casing wall making a visual recording by visually recording perforations, microfractures or other breach type damages of the wall and vertical location thereof on the wall. Selecting a vertical location for sealing the well, the vertical location being determined from the visual recording. Transporting an expandable sealing device being made of an expandable metal and a hydraulic cylinder attached to the sealing device by a shear pin into the well. Expanding the sealing device to engage the casing wall such that a gas seal is made between the sealing device and the casing wall, the sealing device being expanded through engagement by the hydraulic cylinder.
