The tool is driven by the hydrostatic well pressure and activated by added pressure from the surface or mechanical force exerted by the wireline tool string.
The Jet Bailer® is superior to other types of bailers because it generates an extreme jetting force that agitates and loosen objects and debris below the tool. Simultaneously the expelled fluid is sucked back into a fishing chamber together with the debris.
As the tool also ejects fluid, it minimizes the risk of getting hydraulically stuck.
