Abstract
The present disclosure describes a cable head for a wireline tool that includes a housing that comprises an outlet opening for a wireline and an interface configured to connect the housing to the wireline tool; a spool rotatably mounted in the housing; an anchoring point configured for mechanical attachment to an end of the wireline; and a drive configured to rotate the spool and thereby wrap a portion of the wireline around the spool to and retract the wireline into the housing. A wireline tool and a method of retrieving a lost wireline tool are also described.

A cable head for a wireline tool, the cable head comprising:
- a housing that comprises an outlet opening for a wireline and an interface configured to connect the housing to the wireline tool;
- a spool rotatably mounted in the housing;
- an anchoring point configured for mechanical attachment to an end of the wireline;
- and
- a drive configured to rotate the spool and thereby wrap a portion of the wireline around the spool to and retract the wireline into the housing.
A wireline tool comprising:
- a housing that comprises an outlet opening for a wireline;
- one or more sensors arranged in the housing and configured to detect one or more physical properties of a wellbore;
- a spool rotatably mounted in the housing;
- an anchoring point inside the housing that is configured for mechanical attachment to an end of the wireline;
- and
- a drive configured to rotate the spool and thereby wrap a portion of the wireline around the spool to and retract the wireline into the housing.
A method of retrieving a lost wireline tool, the method comprising:
- connecting a first wireline to an anchoring point of a wireline tool;
- lowering, by the first wireline, the wireline tool into a wellbore;
- determining that the first wireline has been severed;
- and
