Abstract

A tool, system, and method for reentry access into a lateral wellbore. The tool, utilized in the system and the method, can include a body with an internal flow passage, an inflatable bladder disposed along an exterior portion of the body, and a flow restrictor that can partially restrict fluid flow through the internal flow passage and create a pressure differential across the tool when fluid pressure rises at an inlet of the internal flow passage. The pressure differential can cause inflation of the inflatable bladder and a surface of the inflatable bladder can be extended radially outward from the body in response to the inflation, where the extended surface can push the tool away from a wall of a main wellbore toward an opposite wall of the main wellbore and divert the tool into a lateral wellbore.
