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 main or branch wellbore below the junction. In described embodiments, formations intersected by a main or branch wellbore below a wellbore junction may be stimulated by fracturing after installing an assembly at the wellbore junction, in a straddling and sealing relationship therewith, to isolate it from pressures applied during the fracturing operation. The illustrated isolation assembly may be installed in a single trip into the main wellbore. |
