Abstract
An improved wireline head and related methods are disclosed. The wireline head can incorporate a release device that allows for a clean cable release while maintaining the portions of the wireline head that were used to retain the cable. For example, the wireline head can include an outer cone and an inner cone configured to trap a portion of a cable, such as armor cabling, between the inner cone and the outer cone. A mechanical link can be positioned within the wireline head, where the mechanical link is configured to separate at a predetermined location such that the cable is freed from the wireline head. A retaining component can be positioned to retain the outer and inner cones within the wireline head after the mechanical link separates.
