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 system and method for maintaining fluid pressure within a well bore includes: (a) an axially reciprocable choke; (b) a mud pump; (c) a programmable controller in communication with the choke and providing operational control of the axial reciprocation of the choke to maintain a set point choke pressure; (d) the controller configured to associate a drilling set point choke pressure within the well bore with a drilling pump rate and associate a predetermined connection set point choke pressure within the well bore with a pump rate; and (e) a mud pump monitor configured to communicate with the mud pump and the programmable controller, measure the pump rate of the pump, and communicate the measured pump rate to the programmable controller.

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.

Abstract: A proportional control valve system and a method for operating the same is provided. The system includes a proportional control valve (PCV), an electric motor, a worm gear drive, and a programmable drive. The proportional control valve has a sealing structure that is positionable in a closed position, a fully open position, and a plurality of partially open positions there between. The worm gear drive is in driving communication with the sealing structure of the proportional control valve. The programmable drive is operable to control the positioning of the sealing structure within the proportional control valve.

Abstract: A hydraulic power unit (HPU) configured for use with a pressure relief valve (PRV) having an open port and a close port is provided. The HPU includes a pneumatic primary pump, a hydraulic fluid reservoir, an accumulator, and a two position solenoid directional valve (TPSDV). The hydraulic fluid reservoir is in fluid communication with the primary pump. The TPSDV is in communication with the primary pump, the reservoir, the accumulator. The TPSDV is configured for fluid communication with the PRV. The HPU is configurable in a PRV fail open configuration and a PRV fail close configuration.

Abstract: A pressure relief valve control system provides a method and apparatus for rapidly closing a relief valve in response to excess fluid pressure. The system uses a programmable controller to rapidly communicate pressure changes to a solenoid actuated valve and two control valves. The solenoid actuated valve has a dedicated accumulator and the two control valves have another dedicated accumulator.

Abstract: The smokeless liquid two-phase burner system of the present invention relates to a method and apparatus for burning a wide variety of flammable liquids using an integrated burner system. The system has both a primary injection path and an alternate injection path for the fuel to be burned, as well as a main air pump or blower. The present invention also provides a method and apparatus for selectably injecting a secondary stream of a gas or vapor or volatile liquid into a flare system for the purpose of enhancing combustion. The apparatus is self-contained and self erecting on a transportable trailer.
