Oil and gas well carbon capture system and method
An oil and gas well carbon capture system includes a controller configured for minimizing or eliminating natural gas flaring and venting. A downhole pump is driven by a motor connected to the controller, which interactively operates a control valve. Controller inputs include gas pressures, pump motor speed and oil and gas delivery. The system is configured for separating production phases comprising oil, water and natural gas. A pressure transducer monitors output to gas sales, which can also be monitored with a digital flow meter. A carbon capture method for oil and gas production is also provided. The controls system maximizes downhole pump efficiency and oil and gas production by interactively monitoring and controlling well operating parameters. A method embodying the present invention optimizes well production and operating efficiency.
METHOD AND ARRANGEMENT FOR OPERATING AN EXTRACTION IN A BOREHOLE
A method and an arrangement for operating a process for extracting a fluid in a borehole are optimized. In the case of deep wells, the location of an interface depth in the borehole is detected. A pressure measurement of the pressure at the head of the borehole is made. The pressure in the liquid in the borehole below the interface depth is determined from the measured pressure at the head of the borehole and the detected location of the interface depth. The determination of this pressure is used for regulating the performance of an extracting device for the liquid that is to be extracted.
Method and apparatus for detecting plunger arrival
The disclosed device provides a high-accuracy plunger arrival detection system comprising a low-power magnetometer with high sensitivity and which is capable of sampling low or high intensity magnetic fields. The device processes gathered data from sensors, stores at least some processed data in memory, executes a trending algorithm which compares the magnetic field of the plunger to the ambient magnetic field or a predetermined set of initialization values, and generates an output which is relayed to a well controller. An output signal may be via hard wire, RF, wireless or other known means. In addition, the implementation of two sensing devices mounted in series and in spaced relation to each other, can provide for an actual plunger average velocity. An actual plunger average velocity, as opposed to approximate average velocity, can be used to better optimize well control and improve safety of the overall well production system.
Lubricator with interchangeable ports
A lubricator is provided which has a unitized body with at least one port in communication with the body's bore and its outer surface, to which port(s) connectors with different outer fittings for further connection to other equipment may be attached and sealed, and later detached and replaced with other connectors. The connectors may have different outer fittings or may be a plug or valve. This allows the connection of a single port to external equipment to be changed and the fitting for that external equipment's connection to be altered, without having to disconnect the lubricator from its well-head and stem or any of the lubricator's other connections.
ARRANGEMENT FOR HYDROCARBON EXTRACTION IN OIL WELLS
An extraction arrangement for the extraction of hydrocarbons that allows reducing related costs by simplifying the structure, reducing the number of parts used in this type of arrangement, and consequently reducing the associated risks and facilitating both operation and maintenance tasks, also optimizing the extraction capacity of the pump by not having leaks in seals because the latter are not necessary as it is a fixed tube.
Apparatus and methods for regulating flow from a geological formation
Aspects of the present disclosure relate to apparatus and methods for regulating flow from a geological formation, and associated components thereof. In one implementation, an apparatus for regulating a multi-phase fluid stream flowing from a subterranean geological formation includes a conduit. The conduit includes an outer wall, a primary flow path for a fluid stream, and a first restriction having a throat portion. A first return path includes a return channel, and the return channel is fluidly connected to the primary flow path through a return inlet and a return outlet. The apparatus includes a gas siphon port formed in the outer wall of the conduit, and a gas siphon path extending from the conduit. The gas siphon path is fluidly connected to the gas siphon port.
DOWNHOLE SEPARATOR
There is provided a system for producing hydrocarbon material from a subterranean formation. The system includes a gas separator for separating gaseous material from reservoir fluid obtained from the subterranean formation. The system is configured to mitigate interference to the separation.
DOWNHOLE HEATER
A downhole heating apparatus may include a gas separator, a downhole heater, and a thermal barrier. The thermal barrier may retard fluid and heat from flowing between a lower annulus of a wellbore and an upper annulus of a wellbore. The thermal barrier may be formed from one or more thermal barrier subcomponents. The downhole heater may be an electrical heater. The thermal barrier may include one or more vents allowing fluid communication between the lower annulus and upper annulus of the wellbore.
MULTI-STAGE DOWNHOLE TOOL MOVEMENT CONTROL SYSTEM AND METHOD OF USE
A multi-stage downhole tool movement control system and method of use, such as a multi-stage movement control system to control the speed of a set of plunger tools when operating within a tubing string of a wellbore, such as when rising within a tubing string of a wellbore. The plunger tools operate in designated stages or zones of a tubing string. In one embodiment, the plunger tools are separated by one or more partitioning tools which transfer accumulated fluid between plungers. In one aspect, the multi-stage downhole tool movement control system includes a system controller operating to control a system valve to regulate the plunger tool speed of a selected plunger. The system controller settings are based on a set of system parameters and characteristics of the selected plunger.
