For the Petroleum Industry , CIS has patented two separate tools for fluid treating.

Downhole Unit DHU 500 To keep subsurface piping clean (production pipe), CIS developed a “Down Hole Unit” which is installed in the flow string in a wellbore.	Surface Unit SUT 400 For all other fluid treating , a “Surface unit” can be used.

To Prevent and Remove Corrosion, Scale and Paraffin deposition on the surface production facilities, tanks, pipelines, and injection wells, Production Separator, Oil transfer station , Water Injection Satation, Cooling waters towers , Boiler stations Steam Turbines or Generators and many other applications, CIS developed the Surface Unit SUT-400

The surface units are custom made designed and built to match the user application. CIS currently has systems in service around the world treating flows from few gallons per day to large facilities handling 20,000 – 40,000 bbls per day and pressures up to 8000 psi and greater.

HOW IT WORKS

The surface unit consists of an outside housing which contains an inside cartridge pf perforated plates. This unique cartridge of plates is  constructed of a patented metal alloy. As fluids enter the surface unit housing, it is directed through these perforated plates. 

The surface unit and plate hole design assure fluid entering the tool will have full contact with this metal alloy, resulting in a polarization effect at the electron level altering the characteristics that prevent the built up of paraffin (wax), scale and corrosion.

To  Prevent and Remove subsurface Corrosion, Scale and Paraffin deposition inside well casing and tubing strings, CIS developed the Downhole unit DHU-500

HOW IT WORK
Inflowing or pumping wells, the produced fluid enters the tool throught the outer holes, causing streams or jets of flow to bombard the alloy walls of the annular chamber and center inserts. Electrons from the walls will react with molecules of the producing fluids, altering the physical characteristics which otherwise clog tubing and impede the upward flow of the produced fluids. The treated produced fluids pass through the tubing string to the surface.

INSTALATIONS
The tool DHU-500 can be easily installed in most all well configurations and flow conditions. In flowing and gas lifted wells, the tool can be run and set using a wireline unit. Therefore killing the well and pulling the well setting is not require. In rod pumped and electric Submersible Pumped wells, the wells setting must be pulled. The tool is installed below the pump at the pump inlet.

SCALE PREVENTION
Scientists and engineers who have investigated scale formation in various industrial systems have determinate that although CaCO3 and MgCO3 form most of the mass in lime type scale , they require silica (SiO2), Alumna (Al2O3) , or calcium sulfate (CaSO4) to act as a cementing agent to bind them together.
The CIS-Tool consist of many dissimilar metals and semiprecious metals that form a special electrochemical catalyst. In addition, the core is configured to prevent flow restriction while providing a high degree of turbulence and increased physical contact between the ions and molecules in the water and the core itself, in order to maximize catalytic efficiency.

PARAFFIN PREVENTION
Crude consist of four factions, namely oil constituents, resin, asphaltene and preasphaltenes (i.e. carbene and carboid ) the chemical and physical properties of crude oils depend significantly on the relative amounts of each faction and their properties. The asphaltenes usually contain more condensed aromatic compounds than the resin and oil factions do. The resins contain aromatic or napthenic hydrocarbons and components of the oil factions may have napthenic or paraffin structures. Asphaltenes and preasphaltenes  in their natural state exist in micelle form. Peptized with resin molecules. The center of this micelle can be metal, clay or water.
The essential feature is that the polar groups ( such S- and/or N- and/or O- containing groups) are concentrated towards the center and produce in water-in-oil emulsion. When crude oil flows into a wellbore, its pressure and temperature decreases. Paraffin and water are released from the water-in-oil emulsion, with the paraffin solidifying at the reduce temperature condition.
The CIS system provides an electrochemical change, which stabilizes the water-in-oil emulsion structure and prevents paraffin from being released from the micelle structure and thus forming solid states.

CORROSION PREVENTION
Corrosion is inhibited if the iron is made more negative compared to its surroundings, forcing the anode areas to act as cathodes. This can be accomplished by attracting some of the polarized molecules (supplied by the CIS-Tool) onto the anodic areas. Thus preventing the ionization of the Fe atoms. The additional polarized molecules also dissolve rust by breaking it into fine colloidal particles. This is done for metal other than iron.

SUMMARY
In accordance with the electro negativities of chemical elements and the oxidation potentials of the elements listed in the Electro negativity Scale and the Electromotive Series respectively, the Corrosion Inhibitor system provides electrons to the fluid solution in a catalytic manner to reduce electron deficiencies in the fluid solution.
This enables electrochemical changes to occur that inhibit scale and corrosion formation , dissolve existing scale corrosion, increase the wetness and cleaning power of water, decrease the gaseous content of water, break down and leach away excess salts from soil, and inhibit algae fungus and mildew growth.
Because of the bipolar (cathodic and anodic) nature of all formed metals, the CIS-Tool removes electrons from some negative ions. However , the CIS-Tool provides a significant net increase of electrons for the ions and colloids in the fluid solution, resulting in inhibition of undesirable oxidation reactions, increase of beneficial reduction reactions and keeping/putting of scale binding particles and rust/corrosion particles in colloidal suspension by providing them with negative charges.
