T-2 On-Off Tool

The T-2 On/Off Tool is a high-pressure, left-hand release tubing disconnect device designed to allow tubing to be disengaged above a packer without disturbing it. This tool is ideal for zonal isolation, tubing retrieval, and temporary zone abandonment, offering flexibility and efficiency in various well operations.

Applications

• Testing: Simplifies disconnection for zonal isolation during testing operations.
• Treating: Facilitates treatment applications requiring temporary tubing removal.
• Production: Enhances production flexibility by allowing seamless tubing disconnection and reconnection.
• Completion: Ideal for use during well completions requiring packer isolation.
• Remedial Operations: Used for troubleshooting or repairing tubing without affecting the packer.

Features & Benefits

• High Pressure Rating: Handles working pressure differentials up to 10,000 PSI.
• Left-Hand Release Mechanism: Ensures reliable operation and ease of use; available in optional right-hand release configurations.
• Auto-On Reconnection: Automatically reconnects to the tubing string for efficient re-engagement.
• Premium Tubing Connections: Customizable to meet specific operational needs.
• Seal Nipple Profiles: Available with various seal nipple profiles to suit different completion requirements.
• Premium Seals: Enhance performance and durability under challenging well conditions.
• Bonded Seals: Support multiple disconnects, maintaining integrity and reliability over time.

Tool Description

The T-2 On/Off Tool is designed as a two-piece system comprising:

1. Running Overshot: Provides a secure connection to the tubing string.
2. Seal Nipple: Contains an internal lock profile to land a wireline plug for zonal isolation below the packer.

This tool is specifically engineered to allow disconnection and reconnection of the tubing string without disturbing the packer, ensuring efficient operations and minimal downtime.

Operational Procedure

1. Installation:
   • Attach the T-2 On/Off Tool to the tubing string above the packer.
   • Run the tubing string into the wellbore to the desired depth.
2. Disconnection:
   • Apply left-hand rotation to release the tubing string from the packer.
   • This enables tubing retrieval or temporary abandonment without affecting the packer’s position.
3. Reconnection:
   • Lower the tubing string back to the packer.
   • The auto-on feature ensures seamless reconnection to the packer, restoring the system for continued operations.
4. Zonal Isolation:
   • The internal lock profile allows the landing of a wireline plug to isolate zones below the packer.

Specifications

• Casing OD Options: Available for 4 ½” (114.3 mm), 5 ½” (139.7 mm), and 7″ (177.8 mm) casing sizes.
• Tubing OD Options: Compatible with tubing sizes ranging from 2 3/8″ (60.3 mm) to 3 ½” (88.9 mm).

Key Advantages

• Supports a wide range of operations, including testing, production, and completion.
• Provides zonal isolation without the need to disturb the packer.
• Customizable for specific well requirements with premium tubing connections and seals.
• Highly reliable in high-pressure environments, ensuring operational efficiency.

The T-2 On/Off Tool delivers unparalleled flexibility and reliability for tubing disconnection and reconnection, making it a valuable asset for well completion and maintenance operations.
