Title: Pressure switch

Description:
TECHNICAL FIELD OF THE INVENTION 
     The present disclosure relates generally to a pressure switch and more particularly to a durable switch that can activate at low pressures while in a high pressure environment. 
     BACKGROUND 
     Hydrocarbons, such as oil and gas, are produced from subterranean reservoir formations that may be located onshore or offshore. The processes involved in recovering hydrocarbons from a reservoir are becoming increasingly complex. Subterranean production is a highly expensive and extensive endeavor and the industry generally relies heavily upon educated predictions of reservoir conditions to characterize the reservoir prior to making substantial investments to optimize well placement within the reservoir, optimize production of hydrocarbons, and performing the necessary steps to produce, process and transport the hydrocarbons from the reservoir. 
     An operation at a well environment may require that a wellhead connection unit (WCU) be brought on site. Typically, one arm of the WCU will connect to a source, for example, a manifold or manifold trailer, that provides or supplies a pressurized fluid and then another arm of the WCU will connect to the wellhead. For example, a crane may be utilized to connect the WCU to the wellhead using a crane. The crane picks or lifts an arm of the wellhead connection unit and moves the arm over to the wellhead. A remote connector is disposed on each arm of the wellhead connection unit. An arm is positioned such that the remote connector of the arm engages the wellhead. Fluid flows from the manifold trailer into a first arm of the WCU coupled to the manifold trailer. The fluid is flowed through the first arm to the second arm of the WCU. The second arm is coupled to the wellhead such that the fluid flows through the second arm to the wellhead. 
     The flow of fluid from the manifold through the arm of the WCU coupled to the wellhead is pressurized. This pressurization may be hazardous to personnel and the surrounding environment. For example, opening up or activating the hydraulics system at the wellhead that connects the remote connector to the wellhead before depressurization may release pressurized fluid. Such a release may cause harm or injury to the surrounding environment including personnel and equipment. A fail-safe system that prevents the remote connector from disengaging from the wellhead while the manifold is pressurized is needed.

     While embodiments of this disclosure have been depicted and described and are defined by reference to exemplary embodiments of the disclosure, such references do not imply a limitation on the disclosure, and no such limitation is to be inferred. The subject matter disclosed is capable of considerable modification, alteration, and equivalents in form and function, as will occur to those skilled in the pertinent art and having the benefit of this disclosure. The depicted and described embodiments of this disclosure are examples only, and not exhaustive of the scope of the disclosure. 
     DETAILED DESCRIPTION 
     At a well site environment, a wellhead is generally coupled to other equipment so that fluid may be flowed to the wellhead. Personnel may be required to assist with engaging and disengaging tubing or piping. For example, a wellhead connection unit (WCU), for example, for example, an ExpressKinect™ Wellhead Connection Unit (EKWCU) or an ExpressKinect™ Quicklatch (EKQL) (both available from Halliburton), at a well site environment may be utilized to provide faster connection of the wellhead to a fluid as compared to traditional rig-up equipment. The WCU, for example, a EKWCU, may comprise a plurality of arms. One arm may couple to a manifold while another arm may couple to the wellhead via a remote connector of the arm. Fluid may flow from the manifold through the arms. The fluid that is flowed to the wellhead may be pressurized. The pressurization of the fluid may vary according to different stages of an operation. Thus, before disengagement of the remote connector, for example, an EKQL, from the wellhead, the pressure must be eliminated or reduced to prevent harm or injury to personnel or equipment at or about the wellhead. 
     To increase safety during operation and to comply with industry or customer-specific requirements, the present disclosure provides a fail-safe switch system or pressure switch assembly that prevents the remote connector from disengaging from the wellhead while pressurized. The fail-safe system must operate or function at both high and low pressures. However, typical pressure transducers have operating ranges that do not span both high and low pressures. According to one or more aspects of the present disclosure, a fail-safe switch system operates or functions accurately at both high and low pressure ranges to provide a safety mechanism that activates at low pressures while maintaining functionality at very high pressures to prevent disengagement of the remote connector for a wide range of pressurization. For example, the fail-safe switch system of the present disclosure may operate accurately from a low pressure threshold of at or about thirty pounds per square inch (PSI) (approximately 206.843 kilopascals (kPa)) to a high pressure threshold of at or about 15,000 PSI (approximately 103421.35 kPa) to 22,500 PSI (approximately 155132.04 kPa). 
     In one or more embodiments of the present disclosure, an environment may utilize an information handling system to control, manage or otherwise operate one or more operations, devices, components, networks, any other type of system or any combination thereof. For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities that are configured to or are operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for any purpose, for example, for a maritime vessel or operation. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communication with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, and a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components. The information handling system may also include one or more interface units capable of transmitting one or more signals to a controller, actuator, or like device. 
     For the purposes of this disclosure, computer-readable media may include any instrumentality or aggregation of instrumentalities that may retain data, instructions or both for a period of time. Computer-readable media may include, for example, without limitation, storage media such as a sequential access storage device (for example, a tape drive), direct access storage device (for example, a hard disk drive or floppy disk drive), compact disk (CD), CD read-only memory (ROM) or CD-ROM, DVD, RAM, ROM, electrically erasable programmable read-only memory (EEPROM), and/or flash memory, biological memory, molecular or deoxyribonucleic acid (DNA) memory as well as communications media such wires, optical fibers, microwaves, radio waves, and other electromagnetic and/or optical carriers; and/or any combination of the foregoing. 
     Illustrative embodiments of the present invention are described in detail herein. In the interest of clarity, not all features of an actual implementation may be described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions may be made to achieve the specific implementation goals, which may vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of the present disclosure. 
     The terms “couple” or “couples,” as used herein are intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection, or through an indirect electrical connection via other devices and connections. Similarly, the term “communicatively coupled” as used herein is intended to mean either a direct or an indirect communication connection. Such connection may be a wired or wireless connection such as, for example, Ethernet or LAN. Such wired and wireless connections are well known to those of ordinary skill in the art and will therefore not be discussed in detail herein. Thus, if a first device communicatively couples to a second device, that connection may be through a direct connection, or through an indirect communication connection via other devices and connections. 
       FIG. 1  illustrates a well site environment  100 , according to one or more aspects of the present invention. Well site environment  100  comprises a wellhead  160  at a surface  130 . In one or more embodiments, wellhead  160  may be located at a subsurface or subsea location. A wellhead connection unit  105  may comprise a hydraulics system  102 , a first arm  140  (for example, a pipe, tube or line) coupled to a remote connector  120 , a second arm  142  (for example, a pipe, tube or line) coupled to a source  107 , and a pressure switch assembly  150 . The remote connector  120  couples the first arm  140  to the wellhead  160 . In one or more embodiments, remote connector  120  may couple any one or more arms  140  to any type of wellhead, to a rig, or to another arm or piping at a surface  130  where the wellhead or arm or piping are at any location. The second arm couples to a source  107 , for example, a pressurized fluid source such as a manifold or manifold trailer. Pressure switch assembly  150  is fluidly coupled to the wellhead  160 . For example, pressure switch assembly  150  may be coupled between the first arm  140  and the second arm  142 . In one or more embodiments, an in-line connector  110 , for example a T-connector, couples the pressure switch assembly  150  to the first arm  140  and the second arm  142 . 
     Pressure switch system  190  comprises a pressure switch assembly  150  and a controller  180 . The controller  180  may be communicatively coupled to the pressure switch assembly  150 . In one or more embodiments, controller  180  is coupled directly or indirectly, wired or wirelessly or any combination thereof to pressure switch assembly  150 . In one or more embodiments, controller  180  may be included within pressure switch assembly  150 . In one or more embodiments, controller  180  may be located at a surface  130  of the well site environment  100  or may be located remotely from the well site environment  100 . 
     In one or more embodiments, the second arm  142  may flow fluid  170  from the source  107  through first arm  140  and remote connector  120  to the wellhead  160 . Fluid  170  may be pressurized at a high pressure by the source  107 . In one or more embodiments, fluid  170  may be flowed at one or more high pressures and one or more flow rates to the wellhead  160  as required by one or more operations, for example, a stimulation operation. The remote connector  120  must withstand high pressures such as those used in stimulation operations and must provide rapid and convenient connection of the arm  140  to the wellhead  160  without damage to any personnel or other components or equipment at the well site environment  100 . While the present disclosure references a stimulation operation, any high pressure operation may utilize any one or more embodiments of the present disclosure. A hydraulics system  102  comprises a hydraulic line  108 , a hydraulic valve  104  and an actuator  106 . The hydraulic line  108  couples the hydraulic valve  104  to the actuator  106 . The actuator  106  is communicatively coupled directly or indirectly, wired or wirelessly or any combination thereof to the controller  180 . The hydraulic valve  104  when actuated by the actuator  106  allows the remote connector  120  to be disengaged from the wellhead  160 . For example, the controller  180  may actuate the actuator  106  when one or more measurements from the pressure switch assembly  150  are indicative of a safe pressure or a pressure that is at or below a pressure threshold. The pressure switch system  190  provides a fail-safe safety mechanism such that the hydraulic valve  104  is not permitted to be actuated when pressurized fluid  170  or pressure at the remote connector  120  is at or exceeds a threshold pressure. 
     In one or more embodiments, the controller  180  may be disposed or positioned within the WCU  105 , proximal to the WCU  105  or remote from the WCU  105 . In one or more embodiments, the controller  180  may comprise an information handling system, for example, information handling system  600  of  FIG. 6 . 
       FIG. 2  is an illustrative pressure switch assembly  150  in a closed position, according to one or more aspects of the present disclosure. The pressure switch assembly  150  comprises a body  202 , a diaphragm  204 , a pin  206 , a compression assembly  208 , a dart  210 , communication pathway  214 , pressure release  216 , adjusting nut  222  and connector  224 . A fastener  212  couples a cap  218  to a first end of the body  202  to position or secure a sensor  220  to the body  202 . A second end of the body  202  comprises a connector  224 . Connector  224  couples the body  202  to the connector  110  of the well site environment  100  of  FIG. 1 . A diaphragm  204  is disposed or positioned within the connector  224 . The diaphragm  204  may be flush, abut, or otherwise proximal to the pin  206 . The diaphragm  204  presses, pushes or exerts a pressure or force against the pin  206  based on a pressure of a fluid  170  that is at or exceeds a diaphragm pressure threshold associated with the diaphragm  204 . For example, a pressurized fluid, such as to pressurized fluid  170  of  FIG. 1 , may be flowed to the wellhead  160  at one or more pressures. As the pressure of the pressurized fluid  170  increases, the diaphragm  204  is deflected or transitioned to an energized position. As the diaphragm  204  transitions to the energized position, the diaphragm  204  contacts the pin  206 . In one or more embodiments, the diaphragm  204  comprises a elastomer material. 
     A chamber  226  may comprise an adjusting nut  222 , a compression assembly  208 , a dart  210  and a pin  206 . The pin  206  is disposed or positioned between the diaphragm  204  and the dart  210 . In one or more embodiments, the dart  210  may be threaded in the pin  206  or otherwise coupled to the pin  206  such that the pin  206  and the dart  210  translationally move together within the chamber  226 . As the diaphragm  204  applies a pressure on the pin  206  based on the pressurized fluid  170 , a pressure is exerted against the dart  210  by the pin  206 . In one or more embodiments, the dart  210  may be disposed at least partially within or coupled to a compression assembly  208 , for example, a spring. An adjusting nut  222  is used to set a preloading force on the compression assembly  208 . The pressure exerted against the dart  210  is compared to a compression threshold and based on this comparison the compression assembly  208  compresses allowing the dart  210  to translationally move towards the sensor  220 . For example, when the pressure exerted against the dart  210  reaches or exceeds a compression threshold associated with the compression assembly  208 , the dart  210  translationally moves towards the sensor  220 . The sensor  220  detects or senses dart. For example, the sensor  220  detects the proximity, positioning, or location of the dart  210  to the sensor  220 . The sensor  220  communicates or transmits one or more measurements or one or more signals to a controller, for example, controller  180  of  FIG. 1 . The one or more measurements or one or more signals may indicate that the proximity, location or distance of the dart  210  is at, about or within a reading range or location associated with the sensor  220 . For example, the dart  210  is transitioned to a location that is sensed by the sensor  220 . This reading range is based, at least in part, on a predetermined safe pressure for disengagement of the remote connector  120 . Generally, the reading range is predetermined based on one or more factors related to safe pressures for disengagement of the remote connector  120  including but not limited to industry standards, customer requirements, specifications associated with the remote connector  120 , any other standard, requirement or specification and any combination thereof. When the diaphragm  204  is deflected such that the dart  210  is at or about the predetermined reading range or location, the pressure switch assembly  150  is in the closed position. 
     In one or more embodiments, the sensor  220  may couple to a controller  180  of  FIG. 1 . The sensor  220  may communicate or transmit one or more measurements or signals to the controller  180 . The one or more measurements or signals are indicative of an unsafe disengagement pressure such that the remote connector, for example, an EKQL, should be prevented from being disengaged from the wellhead. In one or more embodiments, the controller  180  may communicate or transmit a signal to the hydraulic system  102  that causes the hydraulic system  102  to bypass a hydraulic valve  104  that prevents the remote connector  120  from being disengaged from the wellhead  160 . In one or more embodiments, any one or more of the hydraulics system  102 , the hydraulic valve  104 , and the actuator  106  may comprise a manual override. In one or more embodiments, sensor  220  may communicate or transmit one or more measurements or one or more signals to the controller  180  at one or more timed intervals, interrupts, semaphores or one or more other triggers, upon a detected pressure or location of the dart  210  (for example, when the proximity of the dart  210  to the sensor  220  is at or about the pressure threshold), upon a request from the controller  180 , any other criteria, and any combination thereof. 
     In one or more embodiments, a pressure release  216  may comprise a cylindrical aperture that extends from a top of the pressure switch assembly  150  to the chamber  226 . The pressure release  216  may provide a release for any trapped pressure in the chamber  226 . 
       FIG. 3  is an illustrative pressure switch assembly  150  in an open position, according to one or more aspects of the present disclosure.  FIG. 3  illustrates the diaphragm  204  in an unenergized position such that the diaphragm  204  does not press, push or exert a force against the pin  206 . For example, when pressure in the arm or line  140  is at a pressure that does cause the diaphragm  204  to deflect as discussed above with respect to  FIG. 2 , the pressure switch assembly  150  is in an open position and the remote connector is disengageable from the wellhead. For example, to the controller  180  may receive one or more measurements from the sensor  220  and communicate or transmit a signal to a hydraulics system  102  based on the one or more measurements that allows or permits a hydraulic valve  104  to be released and the remote connector  120  to be disengaged from the wellhead  160 . 
     If the pressure switch assembly  150  is in a closed position, as discussed above with respect to  FIG. 2 , once the pressure of the pressurized fluid  170  falls below a pressure level that causes deflection of the diaphragm  204 , the pressure switch assembly  150  transitions to an open position as illustrated in  FIG. 3 . 
       FIG. 4  is a flowchart for controlling disengagement of a remote connector using a pressure switch system  190 , according to one or more aspects of the present disclosure. At step  402 , a pressurized fluid  170  is flowed at a first pressure to or through a remote connector  120  coupled to an arm  140  of a WCU  105  to a wellhead  160 . At step  404 , the pressure switch assembly  150  of a pressure switch system  190  receives the pressurized fluid  170 . Based on the first pressure, the diaphragm  204  of the pressure switch assembly  150  transitions to an energized position. At step  406 , the deflection or transition of the diaphragm  204  causes a pin  206  disposed or positioned between the diaphragm  204  and a dart  210  to press, push, contact or otherwise exert a force against the dart  210 . At step  408 , it is determined if a pressure at the dart  210  exceeds a compression pressure associated with the compression assembly  208  based, at least in part, on any one or more of the first pressure, the diaphragm  204  and the pin  206 . For example, when the first pressure is at or exceeds the diaphragm pressure threshold, the diaphragm  204  transitions to the energized position which causes lathe diaphragm  204  to press against the pin  206 . When the diaphragm  204  presses against the pin  206 , the pin  206  to apply a pressure or force against the dart  210  that exceeds a compression pressure associated with the compression assembly  208 . At step  410 , the dart  210  based, at least in part, on the first pressure and contact with the pin  206  moves transitionally or translationally in a chamber  226  such that the dart  210  is positioned or located at or about a predetermined reading range associated with the sensor  220 . For example, the predetermined reading range or location may be set to indicate that a pressure threshold has been reached or exceeded such that disengagement of the remote connector  120  would cause harm to personnel, the surrounding environment or both. 
     At step  412 , the sensor  220  senses the dart  210  as the dart  210  has translationally moved within the predetermined reading range associated or location with the sensor  220 . At step  414 , the sensor  220  transmits or communicates one or more measurements or one or more signals to a controller  180  of the pressure switching system indicative of the state of the pressure switch assembly  150 . For example, the pressure switch assembly  150  is in a closed position when the dart  210  is within the predetermined reading range or location. In one or more embodiments, the one or more measurements or one or more signals are indicative of the positioning or location of the dart  210 . At step  416 , the controller  180 , after receiving the one or more measurements or one or more signals, determines the state or positions of the pressure switch assembly  150 . For example, the controller  180  determines if the pressure switch assembly  150  is in a closed position based on the one or more measurements or the one or more signals from the sensor  220 . 
     At step  418 , the controller  180  controls disengagement of the remote connector  120  using the pressure switch system  190  based, at least in part, on the determination from step  416 . In one or more embodiments, the controller  180  coupled to the pressure switch assembly  150  communicates or transmits one or more signals to a hydraulics system  102  based on the one or more measurements or the state of the pressure switch assembly  150 . For example, the controller  180  communicates or transmits one or more signals to the hydraulics system  102  that causes the hydraulics line  108  to bypass a hydraulic valve  104  when the pressure switch assembly  150  is in a closed position. Bypass of the hydraulic valve  104  prevents disengagement of the remote connector  120  from the wellhead  160 . For example, the pressure switch assembly  150  transitions between an open position and a closed position based on a pressure and this transition between positions controls the disengagement of the remote connector  120 . 
       FIG. 5  is a flowchart for a method of controlling disengagement of a remote connector  120  using a pressure switching system  190 , according to one or more aspects of the present disclosure. At step  502 , the first pressure at the remote connector  120  is reduced to a second pressure. For example, the pressure of the pressurized fluid  170  flowed through a remote connector  120  coupled to an arm  140  of a WCU  105  is reduced or flow of the pressurized fluid  170  is discontinued or reduced to a second pressure. At step  504 , as pressure of the pressurized fluid  170  reaches or falls below the second pressure, the diaphragm  204  transitions from the energized position as discussed above with respect to  FIG. 4  to an unenergized position. At step  506 , as the diaphragm  204  retracts or transitions to the unenergized position, the force or pressure on the pin  206  is reduced based on the transitioning of the diaphragm  204 . At step  508 , as the pressure on the pin  206  is reduced the dart  210  transitions away or the dart  210  translationally moves in the chamber  226  away from the sensor  220  or outside the predetermined reading range, for example, a predetermined reading threshold or location. For example, the pressure from the pin  206  exerted or applied on the dart  210  is compared to the compression threshold of the compression assembly  208 . Based on this comparison, the compression assembly  208  expands or uncompresses causing the dart to transition away from the sensor  220  toward the diaphragm  204 . 
     At step  510 , the dart  210  is transitioned beyond the predetermined reading threshold or location associated with the sensor  220 . At step  512 , the sensor  220  communicates or transmits one or more measurements or one or more signals to the controller  180 . At step  514 , after the controller  180  receives the one or more measurements, the controller  180  communicates or transmits one or more signals to the hydraulics system  102  based on the received one or more measurements or one or more signals. At step  516 , the hydraulics system  102  engages or actuates a hydraulic valve  104  such that the remote connector  120  is disengageable from the wellhead  160  based on the one or more measurements or one or more signals transmitted by the controller  180 . 
       FIG. 6  is a diagram illustrating an example information handling system  600 , according to one or more aspects of the present disclosure. The controller  180  may take a form similar to the information handling system  600 . A processor or central processing unit (CPU)  601  of the information handling system  600  is communicatively coupled to a memory controller hub (MCH) or north bridge  602 . The processor  601  may include, for example a microprocessor, microcontroller, digital signal processor (DSP), application specific integrated circuit (ASIC), or any other digital or analog circuitry configured to interpret and/or execute program instructions and/or process data. Processor  601  may be configured to interpret and/or execute program instructions or other data retrieved and stored in any memory such as memory  603  or hard drive  607 . Program instructions or other data may constitute portions of a software or application for carrying out one or more methods described herein. Memory  603  may include read-only memory (ROM), random access memory (RAM), solid state memory, or disk-based memory. Each memory module may include any system, device or apparatus configured to retain program instructions and/or data for a period of time (for example, computer-readable non-transitory media). For example, instructions from a software or application may be retrieved and stored in memory  603  for execution by processor  601 . 
     Modifications, additions, or omissions may be made to  FIG. 6  without departing from the scope of the present disclosure. For example,  FIG. 6  shows a particular configuration of components of information handling system  600 . However, any suitable configurations of components may be used. For example, components of information handling system  600  may be implemented either as physical or logical components. Furthermore, in some embodiments, functionality associated with components of information handling system  600  may be implemented in special purpose circuits or components. In other embodiments, functionality associated with components of information handling system  600  may be implemented in configurable general purpose circuit or components. For example, components of information handling system  600  may be implemented by configured computer program instructions. 
     Memory controller hub  602  may include a memory controller for directing information to or from various system memory components within the information handling system  600 , such as memory  603 , storage element  606 , and hard drive  607 . The memory controller hub  602  may be coupled to memory  603  and a graphics processing unit (GPU)  604 . Memory controller hub  602  may also be coupled to an I/O controller hub (ICH) or south bridge  605 .
