Abstract:
A release mechanism for use with a downhole component in a wellbore environment comprises a shifting sleeve disposed about a mandrel, where the shifting sleeve is torsionally locked with respect to the mandrel, a collet prop disposed about the mandrel and engaged with the shifting sleeve, where the engagement between the collet prop and the shifting sleeve is configured to torsionally lock the collet prop with respect to the shifting sleeve, and a collet engaged with the collet prop, wherein the collet couples the mandrel to the downhole component.
