PRODUCTION PROBLEMS?
Paraffin, asphaltenes, and/or scaling deposition will lower net profits by:
- Reduced flow rates
- Lost production hours (down-time);
- High operating costs
- High workover costs
SOLUTION
ENERCAT™ tools will deliver by
- Eliminating paraffin, asphaltenes, and/or scale deposition
- Stabilized continuous production
- Lower overall operating and workover costs
Resulting in substantial increased Profits!
How it works:
Petroleum
crude oil consists of four factions, namely oil constituents, resin, asphaltene
and pre-asphaltene (ie carbene and carboid). The chemical and physical properties
of crude oil depends 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 and may have naphthenic or paraffin structures. Asphaltenes and pre-asphaltenes
in their natural state exist in micelle form, peptized with resin molecules.

The molecule
polar groups such as:
S-negative,
N-negative, and/or
O-negative containing groups
are concentrated towards the center of the micelle. This often is termed oil
external-water internal or water-in-oil emulsion.
PROBLEM - PARAFFIN
Asphaltenes
and Preasphaltenes in their natural state exist in micelle form, peptized
with resin molecules.
When crude oil flows into the wellbore, the pressure and temperature decrease.
This causes paraffin and water to be released from the water-in-oil emulsion
resulting in paraffin solidifying and depositing on production equipment.
ENERCAT stabilizes the water-in-oil emulsion structure and prevents the paraffin being released form the micelle structure and forming solid states.

| Total Fluid Increased | 42% |
| Hydraulic Pressure Dropped | 36% |
| Fluid Levels Increased | 46% |
PROBLEM - SCALE & CORROSION
As petroleum products (including natural gas) are produced, salt and water molecules cause:
Scale build-up that puts
additional stress on the production equipment and
Corrosion that leads to premature failure of production equipment.
SOLUTION
With ENERCAT™ tools installed, scale and corrosion is eliminated, resulting in
- Improved production equipment efficiency
- Prolonged production equipment life
- Less downtime
All yielding increased production.
TEST RESULTS:
| Baiterek
Service Ltd. Republic of Kazakhstan Well located in a field Northeast of the Caspian Sea (paraffin wax 23%) Hot Oil treatment needed 1 to 2 times per month. Chemical treatment once every two to three months Solution: Installation of three ENERCAT™ Tools below the pump in May 2004. |
 |
After
5 Months of production: No Downtime! No hot oil treatment No chemicals! Production up 50%! Pumps operating normally |
Simple one-time installation requiring no maintenance and no power supply
Non-magnetic and non-radioactive. No more hot oiling, wireline knife cutting, downhole chemical treatments
