Abstract:
A release system comprises a torsional lock sleeve disposed about a mandrel, and a collet prop engaged with the mandrel. The torsional lock sleeve and the mandrel are configured to substantially prevent rotational movement of the torsional lock sleeve about the mandrel, and the torsional lock sleeve is configured to shift between a first position and a second position with respect to the mandrel. When the torsional lock sleeve is in the first position, the collet prop is retained in engagement with a collet and the collet prop is retained in a torsionally locked engagement with the torsional lock sleeve. The collet prop is configured to longitudinally translate in response to a rotational movement when the torsional lock sleeve is disposed in the second position. A shifting assembly is configured to engage the torsional lock sleeve and shift the torsional lock sleeve from the first position to the second position.
