CH & CF Hydrostatic Bailer Assembly

The Rebco Hydrostatic Bailer is engineered to remove sand and debris from the wellbore effectively. The tool is sealed at the surface and runs into the well, with the body chamber maintained at atmospheric pressure. Upon reaching the target area, a downward jarring action shears the internal shear pin, allowing wellbore pressure to surge inward. This sudden pressure differential draws debris into the chamber.


Product Code: 168

TOOL APPLICATION

Applications

  • Removing compacted sand, scale, and fine debris accumulations from the top of stuck or obstructed downhole equipment

  • Wells where pump-type bailers cannot generate sufficient suction to lift debris effectively

  • High-pressure wells, where wellbore differential pressure can be used as the driving mechanism for debris recovery

  • Single-trip debris recovery where minimizing rig-up time is a priority


Key Benefits

  • Wellbore pressure drives debris recovery, and tool performance increases in higher-pressure wells.

  • Single jar-down activation is all that is required, simple, reliable field operation.

  • Ball-type (CH) and flapper-type (CF) bottom shoe configurations are available for different debris characteristics.

  • Optional CFM mule shoe bottom for guided entry in irregular debris beds

  • Internal ball valve automatically seals chamber after activation, no manual intervention required at depth.

  • Available 1-5/16"–3" OD in alloy steel construction

RELATED TOOLS

  • As bottom-hole pressure equalizes within the tool body, a ball valve seats, sealing the chamber and securing the collected debris for safe retrieval to the surface.


  • Caution: The pressure should be bled-off before removing the bottom of the Bailer.
