The Pressure Fluctuating Tool (PFT) utilizes a bi-stable, fluidic oscillator to create pulsating pressure for breaking down and/or cleaning up perforations in oil, gas and injection wells with or without stimulation fluids. The pressures generated by the PFT are from 1,500 psi above hydrostatic to 1,500 psi below hydrostatic at 140 to 150 cycles per second. This focused energy has been very successful in perforation tunnel clean up as will be indicated in the detailed case history review contained in this paper.
