DOWNHOLE TUBING DISCONNECT TOOL - A simplified explanation of the abstract
This abstract first appeared for US patent application 17962788 titled 'DOWNHOLE TUBING DISCONNECT TOOL
Simplified Explanation
The downhole tubing disconnect assembly described in the patent application includes an actuation sleeve positioned between two tubing portions in a wellbore. The actuation sleeve selectively connects the two tubing portions and includes a shifting profile to engage a shifting tool within the wellbore.
- The assembly includes a first tubing portion in a wellbore.
- A second tubing portion is downhole of the first tubing portion.
- An actuation sleeve is positioned between the two tubing portions.
- The actuation sleeve selectively connects the first and second tubing portions.
- The actuation sleeve has an uphole portion to engage the first tubing portion, a downhole portion to engage the second tubing portion, and a shifting profile to engage a shifting tool in the wellbore.
Potential Applications
The technology could be used in oil and gas drilling operations to facilitate tubing disconnection and reconnection downhole.
Problems Solved
The assembly allows for quick and efficient disconnection of tubing sections in a wellbore, reducing downtime and increasing operational flexibility.
Benefits
- Improved efficiency in downhole operations - Reduced downtime for maintenance or repairs - Enhanced flexibility in tubing configuration
Potential Commercial Applications
"Downhole Tubing Disconnect Assembly for Oil and Gas Drilling Operations"
Possible Prior Art
There may be prior art related to downhole tubing disconnect assemblies in the oil and gas industry, but specific examples are not provided in the patent application.
Unanswered Questions
== How does the actuation sleeve ensure a secure connection between the tubing portions? The patent application does not provide detailed information on the specific mechanism used by the actuation sleeve to ensure a secure connection between the tubing portions.
== What materials are used in the construction of the actuation sleeve? The patent application does not specify the materials used in the construction of the actuation sleeve, which could impact its durability and performance in downhole environments.
Original Abstract Submitted
A downhole tubing disconnect assembly includes a first tubing portion disposed in a wellbore, a second tubing portion downhole of the first tubing portion, and an actuation sleeve positioned between the first tubing portion and the second tubing portion. The actuation sleeve has a cylindrical body that selectively connects the first tubing portion and the second tubing portion. The actuation sleeve includes an uphole portion of the cylindrical body to selectively engage the first tubing portion, a downhole portion of the cylindrical body to selectively engage the second tubing portion, and a shifting profile in the cylindrical body. The shifting profile selectively engages a shifting tool disposed within the wellbore.
