Abstract
An asymmetric release configuration including a projection, a recess receptive to the projection the recess having a first shoulder that when brought into contact with the projection in a first direction loads the projection in a first way that results in a first release threshold, and a second shoulder that when brought into contact with the projection in a second direction loads the projection in a second way that results in a second release threshold, the second release threshold being different than the first release threshold. A method for operating a borehole including running a configuration into a borehole to a target depth, resisting a load on the configuration in a first direction to a first release threshold, and resisting a load in another direction to a second release threshold different than the first release threshold.
