Abstract: A hydraulic sleeve valve that includes a valve position indication system that provides an indication that the valve has reached a predetermined position, such as, for example, the fully opened or fully closed condition. The hydraulic sleeve valve may include a bypass relief system and may also provide a valve control fluid circulation function to filter or otherwise manipulate the control fluid.

Abstract: A frangible flapper valve that may be closed to hydraulically isolate a portion of a wellbore tubular. The flapper valve is made of a frangible material adapted to shatter upon impact from an impact sleeve. The sleeve may be used to initially hold open the flapper valve. A latching mechanism may be used to retain the sleeve above its initial position allowing the flapper to close isolating a portion of the tubular. The latching mechanism may engage a piston to retain the sleeve at the second position. A shearable device adapted to shear under a predetermined pressure selectively connects the piston to the tubular. When the pressure within the tubular increases above the predetermined amount the shearable device releases the piston and pushes the sleeve into the closed flapper valve causing the flapper valve to shatter. A second latching mechanism may prevent further movement of the sleeve.

Abstract: An isolation system for producing oil and gas from one or more formation zones and methods of use are provided comprising one or more pressure activated and tool shiftable valve assemblies. The tool shiftable valve may be actuated before or after actuation of the pressure activated valve.

Abstract: A radial flow valve is disclosed which includes a plurality of flow openings, a first piston and a second piston, the first and second pistons being independently actuable relative to one another, and a sleeve operatively coupled to the second piston, the sleeve adapted to be positioned so as to cover the plurality of flow openings. A method is also disclosed which includes positioning a radial flow valve in a subterranean well bore having an upper zone pressure and a lower zone pressure, increasing a pressure within the valve to a value above the upper zone pressure to release a first piston within the valve and, after releasing the first piston, reducing the pressure within the valve to a value that is less than the lower zone pressure to thereby cause a second piston within the valve to move and thereby permit fluid flow through the valve.

Abstract: A step ratchet mechanism that allows for the incremental movement of an assembly that may be adapted to incrementally open or close an adjustable orifice. The step ratchet mechanism may be comprised of a modified body lock ring that permits incremental movement along a mandrel in either direction along the mandrel. The step ratchet mechanism may be actuated a designated distance by the application of pressure to the mechanism. The step ratchet mechanism may be ideal for using pressure to drive a downhole multi-position device. The modified body lock ring is adapted to both secure the mechanism at each set position as the mandrel is pumped down as well as allowing the mechanism to ratchet when the mandrel is pumped back.

Abstract: A mechanical flow control device is provided that allows flow of production fluids along an annular path and across an valve body. A sliding sealing member can be mechanically transitioned between an opened flow position and a closed flow position as desired. The mechanical flow control device may be combined with one or more interventionless flow control devices.

Abstract: A mounting assembly that is used to attach an alternate material railing system to an underlying flat surface. The mounting assembly attaches to the underlying flat surface so that the mounting assembly extends vertically upwardly from the flat surface. A hollow post from the railing system is then placed over the mounting assembly and is attached to the mounting assembly. The mounting assembly therefore acts as an intermediate connector that joins a hollow post to an underlying flat surface. The mounting assembly itself has a base plate and a vertical structure extending upwardly from the base plate. The base plate is attached to the underlying flat surface with a mechanical fastener. The hollow post of the synthetic railing system is placed over the mounting assembly, wherein the vertical structure engages the inside of the hollow post and holds the hollow post in a vertical orientation.

Abstract: An interventionless actuator for oil well tools is described wherein the actuator comprises at least one floating piston adapted to equalize a pressure differential and lock onto an actuating member. An interventionless actuator is described that is charged to an initial energy level less than the expected at-depth well pressure and then recharged down hole to approximately the at-depth well pressure by a floating piston. At the time of desired interventionless actuation, the actuator is overcharged to a pressure greater than the at-depth well pressure, which pressure is reacted by an actuating piston to generate an actuating movement.

Abstract: The present invention provides a bi-directional ball seat and method of use. In at least one embodiment, the present invention provides a fluid control system that includes a radial protrusion that can be selectively engaged and disengaged upstream and/or from a ball seat. For example, a ball can be placed in a passageway, engaged with a downstream ball seat, and the radial protrusion radially extended into the passageway distally from the seat relative to the ball. A reverse movement of the ball is restricted by the active radial movement of the radial protrusion into the passageway. The control system can be used to control a variety of tools associated with the well. Without limitation, the tools can include crossover tools, sleeves, packers, safety valves, separators, gravel packers, perforating guns, decoupling tools, valves, and other tools know to those with ordinary skills in the art.
