  • In-situ polymerization method and apparatus to seal a junction between a lateral and a main wellbore
    Patent number: 6015012
    Abstract: An improved method and apparatus for sealing a junction between a central and lateral wellbore is provided. In a broad aspect, the method of the present invention includes installing a polymerizable sealing sleeve within a first casing in a central wellbore at a junction between the first casing and a second casing in a lateral wellbore. After the sealing sleeve has been installed and allowed to cure, a milling tool is used to mill a window through a sidewall of the sealing sleeve and flush with the inner diameter of the second casing. The sealing sleeve may be used alone to establish a primary seal, or in combination with cement or other sealing substance, as used heretofore in prior art sealing methods, as a back-up seal. The sealing sleeve of the present invention may be provided with at least one orienting means to enable the second casing to be located and to direct a well tool thereinto.
