PSB Sand Bailer



The Pinnacle PSB Sand Bailer is a tubing conveyed, high volume pump devise specifically designed for use in low fluid level wells, but equally successful in wells with full hydrostatic columns. The PSB Sand Bailer is used to remove sand and other debris from wellbore by reciprocating the tubing and housing the debris in cavity or fill pipe below the pump.

Like the PSP Sand Pump the PSB Sand Bailer must be submersed in fluid for the pump to work efficiently. The PSB Sand Bailer also utilizes a hexagonal kelly to transmit torque through the pump to aid in breaking up hard packed fill.


The PSB Sand Bailer is made up on the tubing string with the required amount of tail joints between the upper and lower check valves below the pump. The pump assembly must be spaced out so that it will be below the fluid level and in the vertical section for efficient operation. Once on bottom, the pump is stroked up and down. As the fill is being pumped into the cavity pipe, the displaced fluid will go out the ported sub located above the pump. Always maintain the pump assembly in the vertical section and submersed in fluid. Continue this operation until either bottom is reached, the cavity pipe is full or the required amount of fill has been captured in the fill pipe. (See diagram next page for a common Sand Bailer tool configuration)

Common PSB Sand Bailer Configuration with Running Instructions



  1. Fill.
  2. Bit, Spade, Chisel Point, Sawtooth.
  3. Pinnacle Jet Nozzle Sub.
  4. Pinnacle Type F Flapper Valve or Type C Ball Check Valve.
  5. 0.6 m (2 ft) or 1.2 m (4 ft) pup Joint.
  6. Pinnacle Type F Flapper Valve or Type C Ball Check Valve.
  7. Pre-determined amount of cavity (fill) pipe.
  8. Pinnacle Type F Flapper Valve or Type C Ball Check Valve.
  9. Pinnacle Model PSB Sand Bailer submerged in fluid.
  10. Pinnacle Type F Flapper Valve or Type C Ball Check Valve.
  11. Pup Joint for handling.
  12. Flow Sub or Ported Nipple.
  13. Tubing to surface.

NOTE: All connections below pump including check valves should be of the same size and similar diameter to prevent tailpipe from getting stuck. Item 2 is the exception.


Drift, tally and inspect all equipment before running into wellbore. Make up bottom hole assembly as needed and proceed to setting depth.

Tag fill with bit. Set down enough weight to close stroke of PSB Sand Bailer. Ensure PSB Sand Bailer is immersed in fluid. Pumping fluid down the annulus may help in low fluid level well clean outs. Reciprocate tubing to bail fill. For optimum performance pick up full stroke of Sand Bailer. At regular intervals and before making a connection, raise the fill pipe a minimum of 4 m (13 ft) to ensure fill and debris are not accumulating around the fill pipe. If hard fill is encountered and no progress is made by reciprocating the tubing string use the stroke of the pump as a bumper sub to aggressively set weight onto the fill. Torque transmitted by the PSB Sand Bailer kelly through rotation helps to agitate the fill and debris.

To ensure the bit and fill pipe are not resting on fill when making a connection be sure to reciprocate the tubing until the full stroke of the pump is used up.

After clean out is obtained, raise the bit and fill pipe above any perforations and allow the well to sit at least 30 min. Tag bottom again to check for any fill that may have settled out. If no further clean out is needed pull out of wellbore with tools.
