Abstract
A setting and retrieval mechanism for a well tool including a mandrel, a body lock ring disposed on the mandrel, a body lock ring engagement member engaged and disengagable with the body lock ring, and a setting load and retrieval sleeve disposed on the mandrel and having an engagement member support region and an engagement member release region. A method for retrieving a downhole tool including moving a setting and retrieval sleeve to position an engagement member release region of the setting and retrieval tool to allow disengagement of an engagement member with a body lock ring, placing a tensile force on the setting and retrieval sleeve, disengaging the engagement sleeve from the body lock ring under the impetus of the tensile force on the setting and retrieval sleeve, and releasing captured energy in the downhole tool by the disengaging and the tensile force on the setting and retrieval sleeve.
