  • Patent number: 4415269
    Abstract: A reinforced hardened foam lining may be constructed in a particular zone of a well such as a water well, a geothermal well, or an oil well to plug off or contain salt water intrusion or lost circulation by placing a length of perforated pipe in the desired location; placing foam generating components in a foam generating device in the length of perforated pipe; mixing the resin and catalyst (components) forming a mixture of components under pressure which fills the length of perforated pipe, flows through the perforations and fills the voids between the pipe and the side wall of the hole, then swells forming a foam and hardens. The area inside the length of perforated pipe may then be drilled out providing a strong reinforced channel.
