Abstract
Preferential disconnection of a valve-actuating subassembly from a temporary abandonment safety valve and packer assembly is provided by stops which limit relative rotation between the valve-actuating subassembly within the valve along with a locking collar associated with the interconnection between the safety valve and the packer assembly so that high torque associated with rotational movement of a drill string in a highly deviated hole effects the release of the proper portion of the assembly without danger of undesirable release of other interconnections.
