In accordance with the present invention, a plurality of methods and devices are provided for solving important and serious problems posed by lateral (and especially multilateral) completion in a wellbore including methods and devices for sealing the junction between a vertical and lateral well. Methods are disclosed wherein deformable devices are utilized to selectively seal the juncture between the vertical and lateral wells. Such deformable devices may comprise (1) an inflatable mold which utilizes a hardenable liquid (e.g., epoxy or cementious slurry) to form the seal; (2) expandable memory metal devices; and (3) swaging devices for plastically deforming a sealing material.
