Abstract: A coil tubing hanger system and a method of installing such system is provided. The coil tubing hanger system comprises a body having an axial opening there through. A slip bowl having a base and housing a slip that can be retained in a first position spaced apart from bowl base and a second position proximate the bowl base is fitted within the opening. The slip has inner teeth. Tubing is fitted within the slip and through the bowl while the slip is retained in the first position. The slip is then allowed to drop to the second position such that the slip teeth bite onto the outer surface of the tubing.

Abstract: A mandrel rotator is provided is mounted in a housing for coupling to a well casing head. The mandrel rotator comprises of an annular gear having external gear teeth and an axial opening. The annular gear is coupled to a mandrel outer surface, such that rotation of the annular gear causes rotation of the mandrel. A retainer limits or prevents axial movement of gear within the housing. A second gear is coupled to the annular gear for rotating the annular gear.

Abstract: A quick connector fitting assembly is provided which includes a fitting which releasably connects to a well casing for providing an interface for the attachment of various types of well related equipment.

Abstract: This invention includes an above ground compressed gas storage vessel of ular or cylindrical configuration. A plug assembly is inserted into the tube and retained therein by a tri-part ring positioned within a groove of larger internal diameter than that of the tube and retained together with said plug. O-rings or a singular packing assembly would be used to seal the plug to the internal diameter of the tube to prevent the escape of gas. A plurality of cylinders are secured in a parallel arrangement using a support structure to increase gas storage capacity while taking up a minimal amount of ground space.

Abstract: This invention includes an above ground gas storage vessel of tubular or cylindrical configuration. A head or cap with threads mating the threads of the tube is screwed on each end of the tube to form a pressure vessel. Each cap contains a passage therein threaded to mate a reducing bushing. The reducing bushing likewise contains a passage which is at least partially threaded. This passage may be capped to prevent gas flow or valve to allow the flow of gas as required. In an alternative embodiment, the cap assembly is inserted into the tube and retained therein. A packing assembly would be used to seal the tube to prevent the escape of gas. A plurality of vessels are secured in a vertical-parallel arrangement using a support structure to increase gas storage capacity while taking up a minimal amount of ground space.

Abstract: A jacketed valve in which an annular jacket or ring is received over a wafer-type check valve. The ring includes eight axial bores therethrough spaced at 45.degree. intervals to accommodate flange studs when the jacketed valve is received between a pair of pipe flanges. In one embodiment, the annular ring is split in half along a plane normal to the ring axis.

Abstract: A fluid check valve having a cylindrical tubular body member which is symmetrical and is adapted to receive a pair of opposed head members which have suitable coupling ends formed thereon. The head members may be threaded on to the body or secured to the body with pins that prevent transmission of uncoupling torque to head retaining nuts engaged with the body. A valve closure disc is mounted on a removable support ring retained in a counterbore formed in the valve body by one of the head members. A valve seat surface may be integrally formed on a transverse face of one or both of the head members or may be provided as a separate seat insert threadedly mounted on the head members. The head members may be interchanged to accommodate particular coupling arrangements. The seat surface on the downstream head member is protected by a removable wear ring, or a removable wear ring insert is mounted in the head member in place of the seat insert.
