Downhole Fluidics, Inc., is a descendent of PerfClean
International, Inc., which began operations in the Permian Basin Region
of the USA. In early 1990 the company began to investigate various
methods and technologies for treating near wellbore damage. It was
decided to pursue the use of a technology known as “fluidics”
as a means to offer the energy industry a modern and efficient alternative
to traditional treatments. The initial PerfClean© Tool System
was put into service in the spring of 1992.
Downhole Fluidics, Inc., utilizes the PerfClean Tool System Technology, now also known as “Oscillator”, to perform treatments that are designed to remove near wellbore damage of all kinds and restore or increase the porosity and permeability of the near wellbore in all types of wells. These treatments range from the primary stimulation of the formation to remedial workovers. Our tools have been used to treat over 2,500 wells in 12 states and 7 international areas. The treatment design and execution varies according to well conditions the customer’s goals. The current Downhole Fluidics Oscillator has been successfully used to correct problems in wells from 90’ to 27,000’ deep. The Downhole Fluidics Oscillator is built around a patented fluidic oscillator. This oscillator creates pulsating pressure waves within the wellbore and formation fluids. These pressure waves break up any type of near wellbore damage and restore and enhance the permeability of the perforations and near wellbore area. The Downhole Fluidics© Oscillator is run into the well via coiled tubing, conventional tubing, wash pipe or drill pipe. The desired treatment fluid (acid, water, seawater, diesel, nitrified fluids, etc.) is pumped down the tubing through the Downhole Fluidics© tool. The oscillating pressure waves generated by the Downhole Fluidics© tools are not affected by standoff like conventional jetting or velocity tools. The kinetic energy of the pressure pulse travels through the wellbore fluid with no appreciable energy loss. It is only after the pressure wave contacts the formation that this energy is "dumped" and the process of removing the near wellbore damage is initiated. As the damage is removed and the permeability is restored, these pressure waves penetrate deeper and deeper into the formation. These pressure waves expand in a spherical fashion from the point of origin, which ensures that 360-degree coverage is accomplished while moving the tools through the interval. The acoustic streaming induced by the oscillator focuses the treatment fluid and tool energy to the immediate area of the tool, which allows for treating specific intervals. The Downhole Fluidics© oscillators are true fluidic oscillators based on the Coanda Effect. There are no moving parts. They do not rely on cavitation to create pressure waves. There are no packer elements to fail. Unlike mechanical tools, which suffer from high-energy losses, the Downhole Fluidics© oscillator maximizes the energy potential of the pumped fluid. Reports from our customers who have used other tools and "similar" technology show that the Downhole Fluidics© is unsurpassed for long term results. Actual production history shows that while competing tools and technology have similar production increases immediately after treatment, their "increases" drop off dramatically in 2-3 weeks. Actual production history from offsetting wells shows that the Downhole Fluidics© tool results in substantially higher long term production/injection increases. This indicates that the depth of penetration with the Downhole Fluidics© tool is greater than other tools using "similar" technology. |
