SUBSURFACE SAFETY VALVES, ISOLATION TOOLS, AND METHODS OF COUPLING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18064530 titled 'SUBSURFACE SAFETY VALVES, ISOLATION TOOLS, AND METHODS OF COUPLING
Simplified Explanation: The patent application describes a subsurface safety valve with a hinged valve that can be opened or closed to create a fluid-tight seal. It also includes a latching mechanism to secure an isolation tool within the valve, which helps control the flow of fluids in a wellbore.
- The subsurface safety valve has an interior bore and a hinged valve that can be opened or closed to control fluid flow.
- A latching mechanism secures an isolation tool within the valve to help manage the flow of fluids in the wellbore.
- The isolation tool includes a tubular body with an annular seal and an equalization port to maintain pressure balance in the wellbore.
- A control line is used to operate the valve from the surface of the wellbore.
Potential Applications: This technology can be used in oil and gas wells to control the flow of fluids and ensure safety in subsurface operations. It can also be applied in geothermal wells and other underground fluid systems.
Problems Solved: - Ensures a fluid-tight seal in the wellbore - Helps control the flow of fluids in subsurface operations - Maintains pressure balance in the wellbore
Benefits: - Improved safety in subsurface operations - Enhanced control over fluid flow in wells - Efficient pressure management in the wellbore
Commercial Applications: Title: Subsurface Safety Valve for Enhanced Well Control This technology can be used in oil and gas drilling operations, geothermal energy production, and other subsurface fluid systems. It offers improved safety, control, and efficiency in wellbore operations, making it valuable for companies in the energy industry.
Prior Art: Prior art related to subsurface safety valves and isolation tools in wellbore operations can be found in patents and research papers on downhole tools and well control systems.
Frequently Updated Research: Research on downhole tools, well control systems, and subsurface safety valves is frequently updated to enhance safety and efficiency in wellbore operations.
Questions about Subsurface Safety Valves: 1. What are the key components of a subsurface safety valve? 2. How does the isolation tool help control fluid flow in a wellbore?
Original Abstract Submitted
A subsurface safety valve includes an interior bore and a hinged valve actuatable between an open position and a closed position in which the hinged valve creates a fluid-tight seal with the interior bore. A latching mechanism secures an isolation tool within the interior bore of the valve. The isolation tool includes a tubular body having an exterior surface corresponding to the interior bore and an interior surface defining an internal bore. An annular groove is disposed on the exterior surface of the tubular body, and an annular seal is disposed in the annular groove. An equalization port is disposed downhole of the annular seal, and has one or more apertures for fluidly coupling an upper and lower portion of a wellbore. The subsurface safety valve further includes a control line for controlling the valve at a surface of the wellbore.
