The CAVINS “TURBO BAILER” is engineered for fast, efficient well cleanout especially
when large amounts of fill or scale are encountered. It has proven to be a very cost effective
tool over conventional sand line bailers in these situations and unlike the Hydrostatic Tubing
Bailer, the “TURBO BAILER” can be run in shallow or any depth well with a relatively low
fluid level.
The “TURBO BAILER” working barrel chamber is run in the tubing string, utilizing a flap-
per valve placed strategically to insure positive containment of debris inside the tubing.
HOW IT WORKS
The “TURBO BAILER,” in the tubing string, is set into the existing fluid level of the well at
which point the tool is stroked in a manner similar to a sand pump. The up-stroke evacuates
debris from the well upward through the shoe into the tubing and as a result is trapped above
the flapper valve which closes during the down-stroke motion. As fluid reaches the plunger
assembly, it passes through a check valve and is discharged through return ports back into
the well. This stroking is repeated until the tubing is filled with sand and/or debris.
The “TURBO BAILER” offers certain advantages over sand line bailers. The lift rod is of
heavy duty hex design which affords the tool to be rotated with the tubing string to facilitate
getting through sand bridges or breaking up hard packed fill.
The “TURBO BAILER” has additional benefits over conventional circulating techniques
including cost reduction through elimination of expensive pumping equipment and special
circulation fluids (minimizing environmental impact) as well as avoiding the use of high pres-
sure in the well which can force sand back through the perforations and into the formation.
In contrast, the “TURBO BAILER” actually cleans the perforations during operation with its
suction action.
The CAVINS “TURBO BAILER” may be run on all sizes of tubing and drill pipe.
