<p>In accordance with the present invention, a plurality of methods are provided for solving important and serious problems posed by lateral (and especially multilateral) completion in a wellbore including methods for sealing the junction between a vertical and lateral (70) well. Methods are disclosed for improved juncture sealing including novel techniques for establishing pressure tight seals between a liner (88) in the lateral wellbore (70) and a liner (66) in the vertical wellbore. These methods generally relate to the installation of a liner (88) to a location between the vertical and lateral (70) wellbore such that the vertical wellbore is blocked. Thereafter, at least a portion of the liner (88) is removed to reopen (76) the blocked vertical wellbore.</p> |
