APPARATUS AND METHODS FOR ISOLATING A WELLBORE JUNCTION |
摘要 |
A wellbore junction isolation method and associated apparatus provide convenient isolation of a wellbore junction while permitting certain operations to be performed in a wellbore below the junction. In a described embodiment, a formation intersected by a main wellbore below a wellbore junction is stimulated by fracturing after installing an assembly at the wellbore junction to isolate it from pressures applied during the fracturing operation. In this embodiment, the assembly is installed in a single trip into the main wellbore.
