Abstract
Thread leaks, small holes, and leaks around packers in well casings and production tubing are repaired by applying a compressed foam mixture which includes discrete solid particles of various sizes for forcing the suspended particles into the opening to provide a high friction seal. The foam mixture is moved along the inside of the conduit sandwiched between fluid bodies for maintaining the foam mixture intact. Back pressure is applied to the foam mixture for aiding the mixture to be forced through the openings.
