A plunger lift system, as well as a method for monitoring plunger parameters within a wellbore using such a plunger lift system, are provided. The plunger lift system includes a lubricator attached to a wellhead at the surface and a plunger dimensioned to travel through the production tubing upon being released from the lubricator. The plunger lift system also includes magnetic sensor systems installed along the production tubing, where each magnetic sensor system includes a magnetic sensor for detecting the passage of the plunger as it travels through the production tubing, as well a communication device for transmitting communication signals between the magnetic sensor systems and a computing system located at the surface, where the computing system includes a processor and a non-transitory, computer-readable storage medium including computer-executable instructions that direct the processor to dynamically determine the plunger position and/or velocity based on the received communication signals.

A gas separation system can include a gas separator tool, and a gas discharge tool including an inner flow passage formed through a tube and configured to convey separated liquids, and discharge ports configured to discharge well fluids upwardly into an area surrounding the tube. A method of separating gas from liquids of well fluids produced from a subterranean well can include connecting a gas separator tool and a gas discharge tool to a production tubing string, positioning the gas separator tool and the gas discharge tool in the well, so that the well fluids are produced into the gas separator tool, receiving the well fluids from the gas separator tool into the gas discharge tool, and discharging the well fluids from the gas discharge tool into a radially enlarged section of an annulus surrounding the gas discharge tool.

A valve spring fixing device and a plunger pump are disclosed. The valve spring fixing device includes a spring fixing piece, which includes a first supporting surface and a second supporting surface located at two ends of the spring fixing piece, and an intermediate portion located between the first supporting surface and the second supporting surface; and a spring mounting portion connected with the intermediate portion and configured to mount a valve spring, the first supporting surface and the second supporting surface are configured to contact with a valve box to fix the valve spring fixing device.

A vapor recovery turbo compressor is provided for recovering low pressure hydrocarbon vapors from tanks, oil or gas wells or other low-pressure sources. The vapor recovery turbo compressor includes a turbo expander that receives high pressure hydrocarbon gas that drives the turbo expander. The turbo expander drives a vapor recovery compressor. The vapor recovery compressor receives very low-pressure hydrocarbon gas from tanks and other sources and generates medium pressure hydrocarbon gas that can be used for various purposes.

A strong connection that ensures alignment between components and which is capable of being used for high-pressure applications. The connection is held together with one or more pins that are positioned tangentially along the interfacing plane of the components and which pins are positioned such that they are placed in sheer along a significant portion of their length instead of merely across their diameter. The pins can be held in place with one or more structures, which can include threaded fasteners, to prevent the pins from being inadvertently removed.

A low-pressure natural gas harvesting system that injects motive fluid into a first well by a compressor, which flows into a motive manifold that utilizes the Coandă effect to introduce a reduced pressure effect. The reduced pressure effect draws natural gas into the system from natural gas reservoirs through one or more inflow ports that are part of inflow manifolds, which may connect to a motive manifold. The natural gas and motive fluid mix after the motive fluid flows over a Coandă effect surface and the mixture is subsequently directed to flow to a production well.

A system for controlling a flow of fluid includes a flow control device having a fluid channel configured to transport a fluid between a subterranean region and a borehole conduit, a resonant sensing assembly including a resonator body disposed in fluid communication with the fluid channel, and a controller configured to cause the resonator body to vibrate according to an expected resonance frequency of the resonator body. The system also includes a processing device configured to acquire a measurement signal generated by the resonator body, estimate a property of the fluid based on the measurement signal, and control a flow of the fluid through the flow control device based on the property of the fluid.

Aspects of the subject technology relate to systems and methods for optimizing multi-unit pumping operations at a well site. Systems and methods are provided for receiving sensor data from a hydraulic fracturing fleet equipment at an equipment system, designating an event as being flagged based on the sensor data from the hydraulic fracturing fleet equipment, determining a physical action based on the flagged event and a priority list of actions, and providing instructions to a first pump of the hydraulic fracturing fleet equipment to perform the physical action based on the flagged event and the priority list of actions.

Provided herein, is magnetic catch assembly that may be utilized with and/or incorporated into lubricator of a wellhead. The magnetic catch assembly permits maintaining a plunger within the lubricator without requiring any moving mechanical components.

A multistage plunger lift system includes an upper production tubing segment positioned in a wellbore uphole of a lower production tubing segment, with the upper segment having a greater diameter than the lower segment. A lower travelling plunger and an upper traveling plunger are sized and configured to fit and travel within the lower segment and the upper segment, respectively. A plunger lift tool is positioned in the upper segment between the upper plunger and the lower plunger, and includes within its main body a fluid passageway with a one-way valve. A plunger receptacle sleeve at the bottom end of the lift tool receives the lower plunger and includes one or more vents configured to allow fluids to flow around the lower plunger when the lower plunger is received within the plunger receptacle sleeve.
