MULTI-POSITION SLEEVE ASSEMBLY, SYSTEMS, AND METHODS FOR USE IN A WELLBORE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240011370 titled 'MULTI-POSITION SLEEVE ASSEMBLY, SYSTEMS, AND METHODS FOR USE IN A WELLBORE
Simplified Explanation
The abstract describes a multi-position sleeve assembly for use in a wellbore. The assembly includes a tubular housing with an axial bore, a first sliding sleeve, and a second sliding sleeve. The housing has inner and outer surfaces that define one or more first ports and one or more second ports. The second ports are spaced axially from the first ports and are configured for restricted fluid flow compared to the first ports. The first and second sliding sleeves are located in the bore and can be actuated relative to the housing between a closed sleeve position, where the ports are obstructed, and an open sleeve position, where one or both of the ports are not obstructed.
- The invention is a sleeve assembly designed for use in a wellbore.
- The assembly includes a tubular housing with an axial bore, as well as first and second sliding sleeves.
- The housing has inner and outer surfaces that define one or more first ports and one or more second ports.
- The second ports are positioned axially from the first ports and allow for restricted fluid flow compared to the first ports.
- The first and second sliding sleeves can be moved relative to the housing to either obstruct or unobstruct the ports.
- The assembly can be actuated between a closed sleeve position, where both sets of ports are obstructed, and an open sleeve position, where one or both sets of ports are not obstructed.
Potential Applications:
- Oil and gas well operations
- Wellbore stimulation
- Controlling fluid flow in a wellbore
Problems Solved:
- Provides a means to control fluid flow in a wellbore by selectively obstructing or unobstructing ports.
- Allows for restricted fluid flow through certain ports while blocking others.
- Enables precise control over fluid flow during wellbore operations.
Benefits:
- Improved wellbore stimulation and production efficiency.
- Enhanced control over fluid flow in a wellbore.
- Increased flexibility in wellbore operations.
Original Abstract Submitted
a multi-position sleeve assembly for use in a wellbore, comprising a tubular housing defining an axial bore, a first sliding sleeve, and a second sliding sleeve. the housing has an inner and outer surface defining therebetween one or more first ports and one or more second ports spaced axially from the one or more first ports. the one or more second ports are configured for restricted fluid flow relative to the one or more first ports. the first and second sliding sleeves are located in the bore and coaxial to the housing and are actuable relative to the housing between a closed sleeve position, wherein the one or more first ports and the one or more second ports are obstructed, and an open sleeve position wherein, one or both of the one or more first ports and the one or more second ports are not obstructed.
