The field proven Vibration Tool, is a stimulation method for enhanced oil production (EOR) and increased oil recovery. In an amount of jobs performed, an increase of several hundred percent in oil recovery have been achieved, and been continued over several weeks after stimulation, and substantial economic extra value is given.
Stimulation have high efficiency when tool is placed at the oil-bearing zones in the formation. The tool is robust and high efficient even with low pumping rate. Multiple operations can be run in conjunction, e.g. clean up run for scale removal.
