Abstract: A cognate specification system manages and enforces digital, canonical representations of entities that are added to and in the system by creating a composite entity key (“EntityKey”) that uniquely and immutably identifies each entity within the system, and that is created based upon the attributes of the entity rather than being arbitrarily assigned. Entities may be organized into various types or cognates, each associated with distinct sets of attributes. A physical or digital referent may be added to the system as an entity by specifying attributes. In such a system, any entity, whether a physical or digital referent, a process, or other type, is uniquely and verifiably identifiable, and may be linked to or associated with other entities, allowing users of the system to produce and access specification granularity beyond traditional approaches focused on systems interoperability.

Abstract: A multifunction blowout preventer has a housing formed from a single piece of material, which has a central bore, a bottom connection, a gate valve section, an integrated ram assembly/flow tee section, and a top connection. The blowout preventer optionally includes a gas lift/electrical ports section. The components of the blowout preventer are radially offset and/or staggered from one another about the periphery of the housing to help minimize the height of the blowout preventer.

Abstract: An adjustable blowout preventer may be configured to be adjustable, such that a central bore of the blowout preventer may be adjusted or repositioned. The blowout preventer may include one or more adjustment mechanisms for adjusting an angle of tilt of the central bore and/or an offset distance of the central bore. The adjustment mechanisms may be arranged between a stack of the blowout preventer and a wellhead. The adjustment mechanisms may generally be tubular structures having angled and/or laterally offset bores therein. The adjustment mechanisms may be configured to be rotatable, such that rotation of the mechanisms may change an angle of tilt and/or lateral offset of the blowout preventer central bore, or portions thereof.

Abstract: A blowout preventer (BOP) and a seal anti-extrusion apparatus is provided for well control about a tubular such as a polish rod. Each of opposing ram blocks support a semi-circular primary seal and at least one downstream backup ring. An extrusion gap is formed between the ram block and the rod. The backup ring has profile that is axially compressible by the primary seal when activated, causing an inner diameter diminish, and closing the extrusion gap for improved sealing integrity of the primary seal.

Abstract: Apparatus and methodologies are provided for modifying the wellhead structure of a production well to seal the production well before subterranean fracturing operations. The apparatus includes an enclosure tubular and adapter 5 for sealingly engaging the polish rod extending from the wellhead structure, while maintaining the entire rod string in tension in a manner to ensure that the string and its connection with the downhole pump are not compromised. More specifically, the present preparations involve retaining the rod string in tension while removing at least the stuffing box from the wellhead structure, and 10 temporarily installing the enclosure tubular and adapter to seal the wellhead, preventing wellbore blowouts.

Abstract: The present disclosure relates to adjustable blowout preventers and methods of adjusting a central bore of a blowout preventer. A blowout preventer of the present disclosure may be configured to be adjustable, such that a central bore of the blowout preventer may be adjusted or repositioned. In particular, a blowout preventer of the present disclosure may have one or more adjustment mechanisms for adjusting an angle of tilt of the central bore and/or an offset distance of the central bore. The adjustment mechanisms may be arranged between a stack of the blowout preventer and a wellhead. The adjustment mechanisms may generally be tubular structures having angled and/or laterally offset bores therein.

Abstract: An aligning apparatus may include a housing configured for arrangement about a reciprocating rod, a bore extending through the housing and having a size configured to allow the reciprocating rod to pass through the bore in a reciprocating and longitudinal motion, and a plurality of rolling elements arranged along the bore and configured to guide the rod through the bore during reciprocation operations, wherein the housing includes a plurality of portions and is configured for lateral removal from the reciprocating rod. A wellhead assembly having an aligning apparatus and/or a pump jack with an aligning apparatus may also be provided.

Abstract: A system for improving signal timing measurement resolution for an asynchronous measurement signal, the system being adapted to produce multiple phase shifted timing outputs, each having a fixed phase and being representative of timing information for the asynchronous measurement signal, and combine the multiple phase shifted timing outputs to provide a single combined timing output. Preferably but not essentially, the system is configured to produce the multiple phase shifted timing outputs using multiple fixed phase shifted clocks; multiple counters each one associated with one of the phase shifted clocks; and multiple samplers each one associated with one of the phase shifted clocks and its counter, wherein each clock, counter and sampler combination is used to sample the asynchronous measurement signal to produce a timing output, thereby to provide multiple phase shifted timing outputs.

Abstract: Circuits, methods, and apparatus that provide for the powering of active components in connector inserts at each end of a cable may in various ways. For example, where a host is coupled to a device that is not self-powered, the host may provide power for circuitry at each end of the cable. In various embodiments of the present invention, the device may request higher voltage from the host, such that more power can be delivered. In these cases, the device may regulate the voltage received from the host to a lower voltage, and then provide the lower voltage to circuitry at one or both ends of the cable. Where the host is connected to a device that is self-powered, the host and the self-powered device may power their respective connector insert circuits.
