Abstract: A tool for use within a subterranean well extending from a wellhead to a subterranean location, wherein the wellhead resides at a first temperature and the subterranean well increases in temperature in a direction from the wellhead to the subterranean location, increasing from the first temperature to a higher second temperature, includes a component including a meltable material. The meltable material is configured to have a solid first state while the meltable material is at the first temperature. The meltable material in the first state has one or more mechanical properties sufficient to avoid mechanical failure of the component and is configured to have a second state when the meltable material is at the second temperature. The meltable material in the second state is lacking the one or more mechanical properties necessary to avoid mechanical failure.

Abstract: A perforating gun assembly includes a body having an axial length extending between a first axial end and a second axial end, an outer radial surface extending between the first axial end and the second axial end, and an inner bore and at least one explosive charge extending from the outer radial surface to the inner bore. The at least one explosive charge includes a charge casing and a cavity liner mounted within the charge casing. The charge casing and the cavity liner define a charge cavity there between. The at least one explosive charge further includes an explosive material retained within the charge cavity. The at least one explosive charge further includes a deactivation composition retained within the charge cavity.

Abstract: A perforating gun system for use in a well casing disposed within a subterranean well includes a plurality of perforating gun sections each having at least one shaped charge. The plurality of perforating gun sections includes an initial perforating gun section and at least one secondary perforating gun section having an activator and a sensor configured to sense an actuation of another of the plurality of perforating gun sections. The sensor is further configured to cooperate with the activator to actuate the at least one secondary perforating gun section upon sensing the actuation of the another of the plurality of perforating gun sections.

Abstract: A tubing conveying perforating system with a firing head is provided, and a method for using the same is provided. The firing head includes a firing pin and a percussion initiator. The firing pin is configured to degrade over a predetermined period of time from an initial state to a degraded state, and in the degraded state the firing head is inoperable.
