MULTILATERAL BORE JUNCTION ISOLATION

摘要

Abstract A junction can be isolated from fracturing pressure using a liner extending from a one bore through a junction into a lateral bore, where at least a portion of the liner is 5 retrievable from the lateral bore prior to completion of wellbore construction. The junction may be temporarily isolated from high pressure, such as high pressure from a fracturing stimulation process. Part of the liner can be retrieved using a disconnect mechanism or technique. 27/10/15,23171 abstract.doex,2
