Abstract
A sealed branch wellbore transition joint. A method of completing a well having intersecting wellbores includes the steps of: positioning a diverter in a wellbore; diverting an assembly from the wellbore into another wellbore; and swelling a sealing material on the assembly, so that a seal is formed between the assembly and the diverter. A completion system for a well having intersecting wellbores includes a diverter positioned in a wellbore, an assembly extending laterally across the wellbore, and a sealing material on the assembly. The sealing material is swollen so that a seal is formed between the assembly and the diverter.
