Aspects of the disclosure relate to seal assemblies, and associated components thereof, and methods of using the same for use in pressure containing bodies, such as choke valves. In one example, a sensor is used with the seal assemblies. In one implementation, a pressure containing body apparatus includes a pressure containing body including a central opening and a central axis extending through the central opening. The pressure containing body apparatus includes a sleeve disposed in the central opening of the pressure containing body. The pressure containing body apparatus includes an angled seal disposed about the sleeve at an angle relative to the central axis of the pressure containing body. The angle is greater than 0 degrees and less than 90 degrees.

Embodiments of systems and methods for generating power in the vicinity of a drilling rig are disclosed. During a drilling operation, heat generated by drilling fluid flowing from a borehole, exhaust from an engine, and/or fluid from an engine's water (or other fluid) jacket, for example, may be utilized by corresponding heat exchangers to facilitate heat transfer to a working fluid. The heated working fluid may cause an ORC unit to generate electrical power.

Additive is introduced into a tubular that carries produced fluid from a wellhead; the additive addition prophylactically guards against damage to the tubular, such as from corrosion or oxidation. Gas from the wellhead is utilized as a pressure source for driving the additive into the tubular. The rate of additive injection is varied based on characteristics of the tubular or fluid in the tubular. Characteristics of the fluid in the tubular include iron content, residual additive, moisture content, and flowrate; characteristics of the tubular include its corrosion rate of the tubular. The characteristics are measured real time, measured historically, or predicted from a model.

A mechanical indexer for an intelligent flow control valve comprising a plurality of choke positions is provided. The indexer can cycle from a full closed position, to a full open position, to gradually decreasing choke sizes. The indexer can cycle from a full closed position, to a full open position, to gradually decreasing choke sizes alternating with the full open position. The indexer can cycle from a full closed position, to a full open position, to a full closed position, to a full open position, to gradually decreasing choke sizes alternating with a full open position. The indexer can cycle from a full closed position, to a full open position, to a full closed position, to a full open position, to gradually decreasing choke sizes.

A choke includes a cage having a plurality of openings extending therethrough, a first fluid port and a second fluid port, the openings in the cage fluidly interposed between the first and second fluid ports, and a selectively positionable blocking member positioned with respect to the openings to selectively overlie all of a portion of the openings, wherein the surface of the opening extending through the cage are a single crystal material. The single crystal material may be provided as an insert, having an opening therethrough, secured in position with respect to the cage.

A fluid conduit assembly for a fluid supply system includes a low-pressure monobore conduit assembly having a low-pressure monobore conduit and low-pressure outlets. The low-pressure outlets are configured to direct low-pressure fluid from the low-pressure monobore conduit to pumps. At least one first low-pressure outlet is positioned on a first side of the low-pressure monobore conduit, and at least one second low-pressure outlet is positioned on a second side of the low-pressure monobore conduit. The fluid conduit assembly includes a high-pressure monobore conduit assembly having a high-pressure monobore conduit and high-pressure inlets. The high-pressure inlets are configured to direct high-pressure fluid from the pumps to the high-pressure monobore conduit. At least one first high-pressure inlet is positioned on a first side of the high-pressure monobore conduit, and at least one second high-pressure inlet is positioned on a second side of the high-pressure monobore conduit.

An assembly includes an inlet hub (112) coupled to a first flow passage (124) located within a flow control module, the first flow passage having a first flow bore, a flow meter (144) associated with the first flow bore and positioned for top-down fluid flow, a choke (109) disposed in a second flow passage (136) having a second flow bore, and an outlet hub (119) coupled to a distal end of the second flow passage. A system includes a flow control module assembly (902) having an inlet (912) and at least two outlets (914, 916), a main line (920) in fluid communication with the inlet, a first branch line (922) coupled to the main line and to a first outlet (916) of the at least two outlets, and a second branch line (924) coupled to the main line and to a second outlet (914) of the at least two outlets, and a tie-in connector (918) coupled to the inlet of the flow control module assembly.

A pressure management device (PMD) for direct connection to a blowout preventor stack of a managed pressure drilling system, the PMD comprising a housing, one or more chokes, and a directional valve. The directional valve has a choke position and a bypass position. When the directional valve is in the choke position, the PMD operates to divert fluid entering the housing to one or more of the chokes. When the directional valve is in the bypass position, the PMD operates to divert fluid entering the housing to bypass the chokes. The inlet and outlet of each choke may be controlled by a dual shutoff valve, to selectively permit and restrict fluid flow through each choke.

A choke valve including a valve body defining an inlet defining a centrally disposed axis extending through the inlet, an outlet, and a chamber in fluidic communication with the inlet and the outlet, and a flow trim disposed within the chamber and having a side wall that defines a generally cylindrical shape, the flow trim defining a passage through the flow trim, a pair of diametrically opposing windows extending through the side wall, each window permitting fluid communication between the chamber and the passage in a direction orthogonal to the centrally disposed axis defined by the inlet, and a slot extending through the side wall, the slot being disposed substantially equidistantly between the pair of diametrically opposing windows orthogonal to the centrally disposed axis defined by the inlet and on a side of the flow trim opposite the inlet, the slot permitting containment of turbulence created by interaction of fluid flow through the windows.

An apparatus, a system and a process may be used for regulating a wellhead control mechanism. The apparatus may control actuation of the wellhead control mechanism by moving a moveable body of the apparatus between a first position and a second position. When the apparatus is in the first position, a valve actuator is actuatable. When the apparatus is in the second position the valve actuator is physically interfered from actuating. Additionally, when the apparatus is in the second position, the wellhead control mechanism cannot be actuated and is held in either an open, a partially open or a closed position. Further, a system may directly control an actuation of a wellhead actuation mechanism.
