AI Technical Summary
Technical Problem
Existing multilateral wellbore technologies face challenges in efficiently accessing and stimulating multiple lateral wellbores due to limitations in selective access and anchoring mechanisms.
Method used
The use of an expandable metal anchor integrated into a multilateral junction sleeve assembly, which expands in response to hydrolysis to provide a secure anchor and seal within the wellbore, while also incorporating degradable materials to facilitate selective access and operation.
Benefits of technology
This solution enables efficient and selective access to multiple lateral wellbores, allowing for effective pressure stimulation treatments and ensuring reliable anchoring and sealing within the wellbore.

Abstract
Provided is multilateral junction sleeve assembly, a well system, and a method. The multilateral junction sleeve assembly, in one aspect, includes a multilateral deflector assembly, the multilateral deflector assembly including a deflector body having a deflector face and an opening extending therethrough, as well as a deflector assembly sleeve coupled to an uphole end of the deflector body, the deflector assembly sleeve having a sidewall opening in a sidewall thereof aligned with the deflector face. The multilateral junction sleeve assembly in accordance with this aspect, further includes an expandable metal anchor positioned on a radial exterior surface of the deflector assembly sleeve, the expandable metal anchor including a metal configured to expand in response to hydrolysis to axially and rotationally fix the multilateral deflector assembly within a wellbore tubular.
