Description of the Enercat Tool, Application and Process




The Enercat is a downhole tool used for the prevention and removal of scale, paraffin and asphaltene deposition in oil and gas production. When installed in a producing oil or gas well, current treatment methods such as wireline scraping, chemical and hot oil circulation, will be eliminated, resulting in reduced operating costs and stabilized production. The Enercat tool consists of a standard 4 ft production tubing pup joint, with a jacket containing a solid state quartz compound.

Summary of Benefits

Cost Benefits

To illustrate the substantial cost benefits, these are actual figures from a producing oil well in the Pembina area of Alberta over two ten month periods. In the first period the operating company was using a combination of chemical circulation, hot oiling and rig workovers to treat paraffin deposition. On Enercat tool was installed at the end of this period.

Para Service Inc. is a Canadian company with its head office in Calgary, Alberta and distributors in 20 oil producing countries worldwide. The Enercat has been used successfully in over 1000 installations worldwide since 1991, and has proven reliable and effective in preventing and removing scale, wax and asphaltene deposition.



The innovative Enercat tool looks like a standard production-tubing pup joint with a jacket in an aluminum casting. Within this jacket are quartz crystals and semi precious metals that generate a passive energy wave. Petroleum crude oils are made up of factions, which contain paraffin and water. When crude oil flows into a wellbore, pressure and temperature are reduced. As the oil/water solution cools, the paraffins change to a solid form. The paraffin deposits obstruct the flow of crude oil and water particles cause problems. Enercat creates vibrational energy to stabilize the original micelle structure to prevent paraffin from turning into solid form. This allows the solution to move smoothly and cleanly through the pipe without causing deposition problems.


Enercat works in virtually any well that experiences deposition, including dual completions, directional, horizontal, SAGD, water source and water injection wells. Enercat works with any pumping system, with the exception of Electrical Submersible Pumps. Each application is designed for the specific well depending upon tubing size and fluid volume. Typically, Enercats will be run either below the pump intake or above the pump discharge, or as a tail joint at the end of the tubing string. Simple to install, Enercat requires no external power source, maintenance or servicing and has no internal restrictions.

How it works for paraffin

Petroleum crude oil consists of four factions, namely oil constituents, resin, asphaltene and preasphaltene (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 do the resin and oil factions. The resins contain aromatic or naphthenic hydrocarbons and components of oil factions may have naphthenic 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 as S-"negative" and/or N-"negative" and/or O-"negative" containing groups) are concentrated towards the center. This often is termed oil external-water internal or water-in-oil emulsion. When crude oils flows into a wellbore, its pressure and temperature decreases. Paraffin and water then would be released from the water-in-oil emulsion, with the paraffin solidifying at the reduced temperature condition.
Enercat provides a subtle vibrational energy, which stabilizes the water-in-oil emulsion structure and prevents paraffin being released from the micelle structure and forming solid states.

It works for scale

Scale build up puts additional stress on equipment causing premature failure. Enercat eliminates scale deposition to give you increased equipment life and efficiency.

It works for heavy oil

Most heavy oil wells have problems with production because of high viscosity of the oil in the tubing. With Enercat, you get increased flow rates, less torque pressures and less stress on pumps due to changes in viscosity. Once again, cleaner, smoother running well is more efficient and easier on your equipment.


The Enercat represents a major breakthrough in production optimization, reducing operating costs and stabilizing production.
