SYSTEMS AND METHODS FOR PRODUCING HYDROCARBON MATERIAL FROM OR INJECTING FLUID INTO A SUBTERRANEAN FORMATION USING A PRESSURE COMPENSATING VALVE ASSEMBLY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044225 titled 'SYSTEMS AND METHODS FOR PRODUCING HYDROCARBON MATERIAL FROM OR INJECTING FLUID INTO A SUBTERRANEAN FORMATION USING A PRESSURE COMPENSATING VALVE ASSEMBLY

Simplified Explanation

The patent application describes a valve assembly designed to be placed in a subterranean reservoir. The valve assembly includes a valve housing with a fluid passage and an outlet that connects the fluid passage to the reservoir. It also includes a valve sleeve that can be moved between open and closed positions to control the flow of fluid between the passage and the reservoir. The assembly is operated by a hydraulic actuator, which consists of a hydraulic fluid container and a pump.

The patent application also mentions a pressure-compensating system connected to the hydraulic actuator. This system includes a tubing-pressure compensator, which adjusts the fluid pressure within the passage relative to the pressure of the hydraulic fluid container. It also includes a reservoir-pressure compensator, which adjusts the fluid pressure of the reservoir surrounding the valve assembly relative to the pressure of the hydraulic fluid container.

  • The valve assembly is designed for use in subterranean reservoirs.
  • It includes a valve housing, valve sleeve, and hydraulic actuator.
  • The hydraulic actuator is operated by a hydraulic fluid container and a pump.
  • The pressure-compensating system adjusts fluid pressure within the passage and the reservoir.
  • The tubing-pressure compensator adjusts the fluid pressure within the passage.
  • The reservoir-pressure compensator adjusts the fluid pressure of the reservoir.

Potential applications of this technology:

  • Oil and gas extraction: The valve assembly can be used to control the flow of fluids in subterranean reservoirs during extraction processes.
  • Geothermal energy: The valve assembly can be used in geothermal power plants to control the flow of fluids from underground heat sources.

Problems solved by this technology:

  • Efficient fluid control: The valve assembly provides a reliable and efficient way to control the flow of fluids in subterranean reservoirs.
  • Pressure compensation: The pressure-compensating system ensures that the fluid pressure within the passage and the reservoir is properly adjusted.

Benefits of this technology:

  • Improved extraction processes: The valve assembly allows for better control over the flow of fluids during extraction, leading to improved efficiency and productivity.
  • Enhanced safety: The pressure-compensating system ensures that the fluid pressure is properly adjusted, reducing the risk of accidents or damage to the equipment.


Original Abstract Submitted

a valve assembly for disposition within a subterranean reservoir is provided. the valve assembly includes a valve housing defining a fluid passage, and a housing outlet for establishing fluid communication between the fluid passage and the reservoir. the valve assembly further includes a valve sleeve displaceable between closed and open positions for controlling fluid communication between the fluid passage and the reservoir. the valve assembly also includes a hydraulic actuator operable to displace the valve sleeve, the hydraulic actuator including a hydraulic fluid container and a pump. a pressure-compensating system is operatively connected to the hydraulic actuator, and includes a tubing-pressure compensator configured to adjust a fluid pressure within the fluid passage relative to a fluid pressure of the hydraulic fluid container; and a reservoir-pressure compensator configured to adjust a fluid pressure of the reservoir surrounding the valve assembly relative to a fluid pressure of the hydraulic fluid container.
