Summary:A system can include a bottom hole assembly, a wireline and a capillary tube connected to the bottom hole assembly, and a dual pack-off assembly that seals about the wireline and the capillary tube. A method can include connecting a bottom hole assembly to a wireline and a capillary tube, deploying the bottom hole assembly into a wellbore, and increasing pressure in the capillary tube, thereby setting a packer of the bottom hole assembly. A dual pack-off assembly can include a lubricator connector, pack-offs configured to seal about a capillary tube and a wireline, and pipes connected between the respective pack-offs and the lubricator connector.
