Abstract
A shock de-coupler for use with a perforating string can include perforating string connectors at opposite ends of the de-coupler, a longitudinal axis extending between the connectors, and a biasing device which resists displacement of one connector relative to the other connector in both opposite directions along the longitudinal axis, whereby the first connector is biased toward a predetermined position relative to the second connector. A perforating string can include a shock de-coupler interconnected longitudinally between components of the perforating string, with the shock de-coupler variably resisting displacement of one component away from a predetermined position relative to the other component in each longitudinal direction, and in which a compliance of the shock de-coupler substantially decreases in response to displacement of the first component a predetermined distance away from the predetermined position relative to the second component.
