<p>A method for completing a well comprises forming a lateral wellbore 20 extending laterally from a primary wellbore 12 so as to define a junction between the primary wellbore and the lateral wellbore, preventing fluid flow between the lateral wellbore and the primary wellbore, and then permitting fluid flow between the lateral wellbore and the primary wellbore. The method may further comprise installing completion infrastructure 70 in the primary wellbore in the region of the junction between the step of preventing fluid flow between the lateral wellbore and the primary wellbore and the step of permitting fluid flow between the lateral wellbore and the primary wellbore. The completion assembly may be an isolator and may include a timer, a rupture disc, glass disc, flapper valve or ball valve. Also disclosed is an isolator and a well system.</p> |
