Skyline Petroleum Services, Inc. presents PerfClean. 

PerfClean is a line of tools that are used to clean tubulars and tubular perforations insitu.

The first tool in this line originated in the Permian Basin and is based upon leading edge  technology introduced to the field in 1992.  To date, over 3,200 jobs have been performed in twelve states and 10 international areas, worldwide.

This tool was created around a patented fluidic oscillator based on the Coanda Effect. There are no moving parts and the Tool does not rely on cavitations to create the pressure waves. Unlike mechanical tools which suffer from high energy losses, PerfClean Tool maximizes the energy potential of the pumped fluid. Also, there are no mechanical elements to fail. The acoustic streaming induced by the Tool focuses the treatment fluid and tool energy to the immediate area of the Tool, which allows for the treatment of specific intervals.

Skyline Petroleum Services, Inc. offers services utilizing the PerfClean tool to customers in a limited number of countries around the world, such as, countries in the Middle East and Kazakhstan.

How Does Downhole Fluidics Work? 

  • The treatment fluid enters the switch body and is accelerated into the fluidic oscillator. 
  • The fluid stream enters the oscillator and preferentially attaches to the outer wall of one of the fluid passageways. 
  • The flow continues down the selected passageway towards the outlet to the wellbore. 
  • As the flow passes a cross channel, a low pressure area is created which causes the main fluid stream to be interrupted and the flow to switch to and attach to the other fluid passageway. 
  • Continuous flow causes the flow to oscillate from one side to the other which causes alternating bursts of fluid to be ejected into the wellbore. 
  • As each burst is ejected, it forms a pressure wave within the wellbore fluid. Compressive loading occurs when the wave contacts the damage. 
  • As the wave passes through the damage (scale, etc.) and is reflected back, it induces a tensional loading on the skin damage. 
  • The continuous cycling of the pressure waves causes the skin damage to reach its fatigue failure point and break up.
