Systems and methods are described for controlling pressure relief valve (PRV) set points in real-time during various well and drilling operations. An example method may include receiving, by one or more processors, one or more input variables associated with one or more characteristics of a well during a first time period. The method may include calculating a first PRV set point based at least partially on a model of the well utilizing the one or more input variables received during the first time period. The method may include determining whether the first PRV set point is valid based at least partially on a predetermined expected range of PRV set points for the well. Additionally, the method may include transmitting the first PRV set point to a PRV controller when the first PRV set point is determined to be valid.

A method and apparatus are disclosed for providing auxiliary equipment at a subsea location. The apparatus includes a housing including at least one wet mate receptacle connector and at least one wet mate plug connector spaced apart from the receptacle connector, at least one electronic auxiliary device in the housing, at least one connector member extending through a portion of the housing connecting at least one connection element of the wet receptacle connector to a respective at least one connection element of the wet plug connector; wherein the auxiliary device is connected to the connector member in the housing to thereby connect the auxiliary device to the connector member.

An assembly and method for a choke valve body having a choke valve to control flow of fluids. A sleeve positioned in and attached to the choke valve body to flow the fluids through an inner sleeve region internal to the sleeve instead of an outer sleeve region external to the sleeve.

A choke manifold and methods for assembling the same are provided. The choke manifold can include a choke line, a first pulsation dampener in fluid communication with the choke line, and a first choke valve in fluid communication with the first pulsation dampener. The first pulsation dampener is downstream of the choke line and up stream of the first choke valve.

An oil and gas configuration is disclosed that creates and uses a single straight-line fluid path between a zipper module and a fracturing (or Christmas) tree. The single straight-line fluid path is created through connecting a series of valves (e.g., manual or automatic gate or plug valves) that coaxially share inner fluid passageways for transporting hydraulic fracturing fluid between the zipper module and the fracturing tree. The hydraulic fracturing fluid flows along the single straight-line fluid path upon from the zipper module to the fracturing tree. The fracturing tree is equipped with a multi-way block that directsthrough one or more internal angled wallsthe hydraulic fracturing fluid downward and toward a wellhead.

The modular managed pressured drilling system provides multiple skids with individual chokes and PRVs on the skids. These skids secure to one another to construct a modular MPD system that provides the proper equipment for the drilling operation. An inlet flow block and an outlet flow block are secured to each skid. The flow blocks provide multiple apertures to provide different pathways for the drilling fluid through the flow blocks. The flow blocks may direct the fluid through a first choke, a second choke, a pressure relief valve, or a bypass.

A choke valve is provided that includes a valve body, a plurality of seats, and a gate. The valve body has an inlet port and an outlet port. The plurality of seats is in communication with the valve body, where each seat has a fluid flow configuration, and the fluid flow configuration for each seat is different from the fluid flow configuration of each of the other seats within the plurality of seats. The gate is linearly translatable along a gate axis. The valve body is configured so that so that one of the plurality of seats at a time is selectively positionable in an engagement position aligned with the gate axis.

An intermitter valve for controlling the flow rate and/or pressure of a fluid produced from a well drilled into an oil and gas reservoir includes several seals between a seat connected to the valve body and a sleeve connected to a reciprocating stem. An O-ring disposed in an inner groove of the sleeve can be used to intermittently form an elastomer-to-metal seal against the seat. An O-ring disposed in an outer groove of the seat can be used to intermittently form an elastomer-to-metal seal against the sleeve. A surface proximate to the end of the sleeve can be used to intermittently form a metal-to-metal seal against a surface of the seat. The seat and the sleeve can be part of a valve kit for converting a production choke valve into a flow shut-off device.

A wet Christmas tree (WCT) is segmented into a lower safety module containing safety valves and an upper multifunctional module for controlling the flow and/or pumping and/or subsea processing. The WCT can be applied to completion systems using completion mode with tubing heads or directly on the wellhead. The modular WCT can be used in oil and gas production well applications or injection of water and/or gases in subsea fields in shallow water to deep water.

Embodiments of the present disclosure relate to an apparatus, a system and a process for regulating a wellhead control mechanism. The apparatus is configured to control actuation of a 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 and when the apparatus is in the second position the valve actuator is physically interfered from actuating. 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. Other embodiments of the present disclosure relate to a system that directly controls actuation of a wellhead actuation mechanism.
