Fluidic oscillation started as a comprehensive method to remove skin damage from new perforations and has evolved into a complete treatment system that can incorporate other tools as well as fracturing techniques. Hydraulic fracturing treatments,"Frac" jobs, have become the industry standard in many areas for correcting fluid entry problems and prior to the invention of the true fluidic oscillator, frac treatments were often seen as the most effective and "necessary" solution to the problem at hand even though they come with a high price tag.
Working with a formation with very low permeability such as "tight" (< 0.1 md) sands, frac treatments are usually necessary to establish economical production, however, there are many formations around the world that have relatively high permeability. Until the advent of the fluidic oscillator technology, it appeared prudent to order a frac job which in reality breaks through and bypasses the damage rather than re-establishing the flow path by removing the restrictions to production.
When dealing with moderate to high permeability or naturally fractured formations, using the true fluidic oscillator has proven to be extremely successful in establishing commercially economical production rates, in some cases surpassing frac rates, by re-connecting the perforations with the reservoir, opening clogged formation pore spaces and removing the near wellbore formation damage created during the drilling, completion, and production phases.
The TFO tool system is designed to remove this damage and enhance the native permeability found in the formation. Fluidic oscillation treatments have been performed that have resulted in higher initial production rates as compared to frac jobs. After one year, these same treatments are still producing oil at a higher rate compared to wells that were treated by hydraulic fracturing. The key difference is that the fluidic oscillation treatment removes the material that restricts production instead of bypassing it. More on treatment comparisons.
