JDC Pulling Tool

Technical Description and Specifications

The JDC Pulling Tool is a slickline intervention device classified as a Jar-Down-to-Collect (JDC) selective pulling tool. It is specifically designed to engage, unlock, and retrieve downhole flow control devices (e.g., plugs, safety valves, standing valves) that utilize a standardized internal fishing neck profile where a downward jarring impact is required for initial collection or unlocking.

Key Technical Specifications and Operation

• Function: To retrieve subsurface control devices by engaging the fish neck and releasing the tool string’s core only after a controlled downward impact has unlocked the downhole device.

• Design: A multi-component assembly featuring a spring-loaded core and external pulling dogs or fingers. The core is held in a lower position by shear pins.

• Mechanism (Controlled Release): The tool is run downhole over the target fish neck.

  1. Engagement: The dogs engage the target fish neck profile.

  2. Collection/Unlocking: A downward jarring action shears the pins, allowing the internal core to move down relative to the body.¹ This movement pulls the dogs inward, locking the tool onto the fish neck and simultaneously unlocking the downhole device.

      

  3. Retrieval: Once locked onto the fish, an upward pull retrieves the device. The JDC is retrieved locked to the fish.

• Shear Pin Rating: Utilizes precisely sized and rated shear pins to control the required downward impact load, ensuring controlled tool action and preventing damage to the tool string or completion.

• Connection (Customizable):

  • Standard interfaces include industry-standard slickline pin threads (e.g., $15/16″-10$ UN, $1-1/16″-10$ UN).

  • Custom order connections are available to ensure interchangeability with all major competitor proprietary threads and specialized quick-connect systems.

• Material (Customizable):

  • Standard construction uses high-strength alloy steel (e.g., AISI 4140).

  • Custom material options are available, including NACE MR0175 compliant alloys for sour service and high-corrosion environments.

• Critical Parameters (Customizable Size & Shear Ratings):

  • Fish Neck Profile: Tools are fabricated to match specific target fish neck profiles (e.g., Otis B, X, R) and sizes.

  • Shear Pin Rating: Clients must specify the target fish neck profile (type and size) and the required shear-down release load when placing a custom order.
