Zusammenfassung:An apparatus can include a cable head assembly with a cable head stinger connected to a weak link, and a release assembly including a bushing that radially outwardly supports a dog in engagement with an internal groove formed in an outer housing. A method can include connecting a bottom hole assembly to a wireline, the connecting including connecting the wireline to a cable head stinger of a cable head assembly; deploying the wireline and bottom hole assembly into the well; applying a tensile force to the wireline, thereby breaking a weak link of the cable head assembly; and then displacing the cable head stinger into engagement with a bushing of the release assembly, thereby permitting a dog to displace radially inwardly out of engagement with an internal groove in the release assembly.
