Abstract: A greasing system may be placed partially within the red zone and partially outside of the red zone. Grease and pneumatic power is supplied from outside of the red zone to a pod, inside of the red zone, having local storage, high-pressure pumping capacity, and a distribution mechanism. The grease is supplied from outside of the red zone to the pod at low-pressure through a hose having at least a 1 inch inside diameter and is usually at least 100 feet long. The pod pressurizes the grease to a high-pressure and distributes the grease via a distribution mechanism to a relatively short hose, generally less than 8 feet between the distribution mechanism and the greasing point on the wellhead, in order to minimize pressure losses.

Abstract: A hydraulic accumulator system is provided to remove the motors or engines from the red zone while maintaining sufficient capacity within the red zone to quickly close the designated blowout preventer or other gate valves. Additionally, a single point is provided outside of the red zone to charge the local storage units or to open or close the designated blowout preventer or other gate valves when time is not a critical consideration.

Abstract: A sensor system to prevent the unintended severing or damage to a cable or other object within the throughbore of a standpipe or wellhead that may include a blowout preventer and gate valves. Generally, a sensor which may include both an emitter and receiver, is affixed externally to the standpipe, wellhead, blowout preventer, or gate valves. None of the emitter or receiver penetrates the pressure vessel formed by the standpipe, wellhead, blowout preventer, or gate valves. The sensor system may detect disturbances in a pre-existing field such as a geomagnetic sensor detecting the earth's magnetic field, the sensor may create a field and then detect disturbances within that created field such as a magnetic sensor, or the sensor may send a pulse of energy towards the area to be sensed and then read the reflected energy. Generally, the sensor system includes a logic controller, a memory, a sensor or sensors that may or may not include emitters and receivers, and a display.

Abstract: A sensor system to indicate whether or not the gate valve is open, closed, or at some position between. In certain instances, two sensors may be used to indicate the position of an attachment to the gate within the gate valve thereby indicating whether or not the gate within the gate valve is fully opened or fully closed. In other instances, a single sensor may be utilized to indicate the position of an attachment to the gate within the gate valve such position being between and including fully opened and fully closed. Generally, a sensor which may include both an emitter and receiver, is affixed externally of the pressurized portion of the gate valve or other type of valves.

Abstract: A wellhead is provided having a port or ports about the external periphery of the wellhead. The center bore of each port is generally directed at a point within the wellhead having a location where a portion of a tool or an object is expected. Each port does not provide fluid access from the exterior to the interior of the wellhead and preferably has a flat bottom. Each port is fitted with a sensor and preferably the sensor contacts the bottom of the port. And ultrasonic a sensor emits an ultrasonic waveform which proceeds through the bottom of the port and a portion of the ultrasonic waveform is reflected back to the ultrasonic receiver. A comparison is then performed to compare the predicted value versus the received value to determine whether or not the expected tool or object is in place or partially in place within the wellhead.

Abstract: An artificial lift system has a surface pump operated by a prime mover powered by a variable speed drive. A jet pump disposed downhole in tubing receives pressurized power fluid from the surface pump, mixes the power and production fluid and delivers the product uphole. A controller disposed at surface adjusts the artificial lift system relative to a set value based on a measured discharged pressure or a measured flowrate and trends a change in the other of the measured flowrate or the measured discharged pressure over time. The controller can also trend an operating condition (intake pressure vs. production rate) to determine changes relative to cavitation conditions. Based on the trended changes, the controller initiates an operation in the artificial lift system, such as adjusting the discharge pressure, initiating an alarm condition, etc.

Abstract: A wellbore completion is configured for multiple forms of artificial lift. A downhole assembly on production tubing defines a production port communicating a throughbore with the wellbore annulus. A bypass, such as a snorkel or riser tube, on the assembly also communicates the throughbore between the packer and the production port with the annulus. A packer on the assembly seals in the annulus downhole of the production port and bypass. The assembly can then be configured for any selected artificial lift. To do this, at least one isolation (a sleeve insert, a sliding sleeve, a check valve, or a rupture disk) selectively prevents/allows communication via one or both of the production port and the bypass as needed. Additionally, removable lift equipment, including jet pump, gas lift valve, plunger assembly, rod pump, piston pump, or standing valve, is selectively inserted into the assembly's throughbore as needed.

Abstract: In some aspects, the present disclosure provides a method of allocating memory resources on a system-on-chip (SoC). The method includes receiving audio data from a first master, the first master being an audio subsystem. The method further includes receiving non-multimedia data from a second master, the second master being a non-multimedia subsystem. The method also includes communicating the audio data to a first partition of the memory management unit circuit, where the first partition is configured to be accessible by the first master and not the second master. The method further includes communicating the non-multimedia data to a second partition of the memory management unit circuit, where the second partition is configured to be accessible by the second master and not the first master, and where communication of the audio data is prioritized over communication of the non-multimedia data.

Abstract: A plunger lift method can include introducing a plunger sleeve and a plunger closure into a well, engaging the sleeve with the closure, securing the sleeve and closure to each other in a flow passage of the well, and then retrieving the sleeve and closure from the well. A plunger lift system can include a plunger sleeve configured for reciprocal displacement in a flow passage of the well, a plunger closure configured to block flow through a flow path of the sleeve and being displaceable in the flow passage separate from the sleeve. A plunger retrieval device may displace with the sleeve in the flow passage and secure the closure against displacement away from the sleeve. Another plunger retrieval device may be positioned in a lubricator, whereby the plunger retrieval device engages the closure and secures the closure against displacement away from the sleeve in the lubricator.

Abstract: A machine has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to receive data from a data source that continuously generates records, selectively identify conditions within the data that satisfy specified rules, and report the conditions prior to routing the data to a message system node forming a segment of a distributed transaction log with messages persisted in non-volatile memory and replicated within a cluster of nodes.

Abstract: A network gateway is implemented on behalf of a customer entity. The network gateway may be implemented using a distributed computer system and the network gateway may connect a network of the customer entity to a public communications network. The network gateway may include network-related services without the need for adding specialized hardware. The network gateway may be provisioned programmatically in response to instructions received from the customer entity. The network gateway may be provisionable and accessible over several different types of data connections. The network gateway, by virtue of being implemented on a distributed computer system, is scalable upon demand without additional input by the customer entity.
