Abstract
A release mechanism for incorporation into a logging head. The release mechanism may be a tensile release mechanism that employs a plurality of tensile members for interchangeable insertion into a plurality of tensile compartments. As a result, a weakpoint for the logging head may be user defined on location at the oilfield. Furthermore, for potentially deeper wells, a rotatable release mechanism may be alternatively or additionally incorporated into the logging head. The rotatable release mechanism may be employed to effectuate a release of the logging head upon signaling from surface equipment. Additionally, the rotatable release mechanism may be powered to achieve the release solely from a downhole power source.
