Hydrostatic bailers and wireline jars (hydraulic suction bailer)

The Cavins Hydrostatic Bailer has been used in all types of clean-out work in producing wells and in drilling and workover operations. Its principle use of hydraulic suction provides several distinct advantages that cannot be obtained with any other type of wireline cleanout tool.

Rod-Type Sand Pump

Cavins Sand Pumps are designed for clean-out work where it is not desired to flush the producing formation with hydrostatic fluid surges, or where extremely low fluid levels prevent efficient use of the Cavins Hydrostatic Bailer.

The Cavins Hydrostatic Tubing Bailer is the most effective tool available for recovering sandfill and small junk from open or cased holes. The Hydrostatic Bailer can be run on tubing or drill pipe, and it functions without surface pumps.

The Model DA Tubing Pump may be run on tubing or drill pipe. The tool's hexagonal Kelly transmits surface rotation of the pipe to the lower end of the pipe whenever rotation or drilling is required.
