Purpose of the Ball Catcher
-The ball catcher is a component located below the ball seat inside the PBL sub.
-It retains the dropped ball after it has served its purpose (opened or closed the ports).
-Prevents the ball from going further downhole and potentially damaging tools or blocking nozzles.
Reasons to Remove the Ball Catcher
- Maintenance or Redress
-After multiple activations, the ball catcher may need inspection for wear or damage.
-During redress, removal allows full internal access for cleaning or replacing components. - Compatibility with Larger Balls or Special Operations
-Some operations might require dropping larger balls or allowing free passage of fluids or tools.
-Removing the ball catcher may be necessary if it restricts this function. - Modifying Tool Functionality
-In some cases, operators choose to remove the ball catcher to convert the PBL sub into a one-time use tool or passive port.
Typical Steps in Removing Ball Catcher (General Procedure):
- Ensure tool is on surface and properly secured in a vise or cradle.
- Disassemble the sub per redress manual.
- Remove retaining rings/screws or any locking mechanism.
- Extract the ball catcher using pull tools or hydraulic force if required.
- Inspect internal bore for damage or debris.
- Reassemble or replace components as necessary.
