This disclosure presents a latch back pressure valve for use with a wellhead assembly. The latch back pressure valve includes a body and at least one seal extending circumferentially around the body. A plurality of extendable latches are supported by the body and configured to engage with corresponding locking grooves. A poppet is configured to be displaced to open a passageway through the body. A hold-down ring is configured to engage a miming tool such that rotation of the miming tool causes the plurality of extendable latches to an extended position.

Systems and methods include a computer-implemented method for determining an integrated surface-downhole integrity score for a natural flow oil well. Wellness surface parameters of a natural flow oil well are determined. Wellness downhole parameters for the natural flow oil well are determined, including parameters indicating well integrity and tubing/casing conditions. An integrated surface-downhole integrity score is determined using the wellness surface parameters and the wellness downhole parameters. An alert is provided for presentation to an operator in a user interface. The alert is provided in response to the integrated surface-downhole integrity score exceeding a threshold.

A hydraulic fracturing system can include valve apparatuses that control the delivery of fluid to high-pressure pumps that supply the fluid to a wellhead. The valve apparatuses can receive electronic signals from a control system to regulate the flow rate of the fluid to the high-pressure pumps. In one or more examples, the flow rate of the fluid can be controlled such that proppant in the fluid remains in solution.

Fracturing systems with frac valves for controlling flow of fracturing fluid are provided. In one embodiment, a fracturing apparatus includes a frac valve having a housing with a bore to convey fracturing fluid, a seal disposed within the bore, and an actuator coupled to control movement of the seal. The actuator can be disposed within the bore so as to move the seal between a closed position in which the seal blocks fracturing fluid flow through the bore and an open position that allows fracturing fluid flow through the bore. Additional systems, devices, and methods for fracturing are also disclosed.

An annulus pressure release system includes a gas metering valve assembly having a fluid pathway. The gas metering valve assembly includes a pressure sensor configured to be fluidly coupled to an annulus and to output a sensor signal indicative of a fluid pressure within the annulus. The gas metering valve assembly also includes an electronically actuated adjustable control valve disposed along the fluid pathway and a electronically actuated two-position valve disposed along the fluid pathway. Furthermore, the gas metering valve assembly includes a flow controller. The flow controller, in response to determining the fluid pressure exceeds a threshold pressure, is configured to output a first control signal to the electronically actuated two-position valve indicative of instructions to open the electronically actuated two-position valve, and to output a second control signal to the electronically actuated adjustable control valve indicative of instructions to adjust a flow of fluid through the fluid pathway.

A valve block may be assembled, in a controlled environment, a valve block to be modular and purpose built for a specific application. The specific application may be an operation to be performed at a well site. The modular purpose built valve block may be function tested, in the controlled environment. Additionally, the modular purpose built valve block may be pre-packaged, in the controlled environment, to have a digital system to operate and automate the modular purpose built valve block. Further, the modular pre-packaged purpose built valve block may be deployed to the well site, and the modular pre-packaged purpose built valve block may be fluidly coupled to a wellhead. The modular pre-packaged purpose built valve block may be operated to perform the operation at the well site.
