Frequently Asked Questions (FAQs)

  1. What is the Bailer Float Sub – 3.75″ used for?

    The 3.75″ Bailer Float Sub is designed to work in conjunction with a bailer system to assist in the removal and transport of sand, debris, or other material from the wellbore. It provides a full 1.5‑inch I.D. flow path and incorporates a flapper valve for efficient debris capture.


  2. Why choose the 3.75″ size model?

    The 3.75″ size is ideal for wellbores or casing sizes where you need a float sub that balances flow area with compact diameter. It keeps strong internal flow while fitting typical intermediate casing dimensions. The 1.5″ internal diameter aids in transporting debris effectively.


  3. How does the flapper valve design benefit the operation?

    The built‑in flapper valve allows debris to pass from the wellbore into the debris chamber and then closes securely for retrieval. This prevents wash‑back of the material and ensures collected debris stays captured during the trip out of hole.


  4. What operating conditions are ideal for this tool?

    This float sub excels in clean‑out operations where you are running a bailer in low‑fluid or non‑circulating conditions and need reliable debris capture and transport. It’s best when paired properly with your bailer and when well fluid and string conditions allow for the required I.D. and flow path.


  5. Can the Bailer Float Sub – 3.75″ be customized for specific job requirements?

    Yes — Bull Dog Tool offers additional sizes, models, and configurations tailored to your job requirements. If you have unique casing sizes, debris types, or bottom‑hole conditions, you can contact your Bull Dog representative to specify custom build‑outs.
