Hydrostatic Bailer

The Hydrostatic Bailer is a wireline service tool used to clear the debris which has settled on the top of the subsurface equipment, preventing the recovery of the equipment by regular wireline operations. The Hydrostatic Bailer is specifically designed for use when the debris cannot be removed from the well with a Sand Pump Bailer.
The bailer upper portion consists of a chamber, sealed at atmosphere pressure, with a relief plug at the upper end and a shear piston at the lower end. The piston is secured to its housing with shear pins. When debris had been reached, downward jarring will shear the pin securing the piston to the housing. Well pressure will cause the piston to move rapidly upwards and the suction created will draw debris into the tool.

Other sizes are available on request.
