DB Dump Bailer Assembly

The Rebco DB Dump Bailer is engineered to deliver fluids or solids directly onto a sub-surface device within the wellbore. The tool is filled via a large port on the top (fill) barrel. Once positioned above the target device, a downward jarring action shears the shear pin, activating the shear plunger and rupturing the shear disc. This sequence releases the contents onto the sub-surface device.


Product Code: 168

Applications

  • Depositing acid, chemical solvent, scale inhibitor, or paraffin dispersant onto a specific downhole obstruction or treatment zone

  • Delivering cement, fluid plugs, or sealants to a target interval in a single controlled dump

  • Chemical treatment of stuck downhole equipment to assist in loosening or recovering tools

  • Controlled delivery of any fluid requiring precise depth placement in the wellbore


Key Benefits

  • Depth-specific fluid delivery in a single wireline run, no circulation or pump trucks required

  • Shear disc activation requires no complex mechanical action; it is a straightforward jar-down operation.

  • Shear disc material and thickness selectable at the surface for precise activation force control

  • Extension barrels available for high-volume treatment requirements

  • Lower foot OD customizable to match the target device or interval

  • Available in 1½" – 4" OD in standard threaded connections

  • If the volume needs to be increased, install a Connector Sub and Tandem Barrel.


  • Product Code: 168


  • Rebco DB Dump Bailers can be manufactured and supplied to suit any required application. It is recommended to specify type of medium to be carried down hole.
