EOR Through Electro Treatment
• Oil well treatment through Electro Treatment increases the output of aging oil fields while decreasing the water-cut
• Major breakthroughs in utilization of Electro Treatment in the oil field occurred 17 years ago and have been perfected by our partner in Russia
• Mr. Alexander Rybakov (presently a team member and researcher for Advanced Oil Recovery Technologies) was the lead pioneer of this technology
• Hundreds of field tests have been conducted in countries worldwide, including Russia, Kazakhstan, India, Brazil and former Soviet states

EOR Through Electro Treatment
The Electro Treatment technology is based on the effects of changing the cavitated spatial pattern within the rock of a reservoir and spacious structure of two-phase liquid filtration (oil & water) in the reservoir as a result of repeated cycles of electric pulses.
Electro Treatment Theory
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
Utilizing the existing production casings from two well points as “antennae” electrical waves are modulated directly into the reservoir at both high and low frequency.Treatment is portable, short term and has relatively no infrastructure cost.

If the capillary sections radii ratio R1 / R2 = 3.2 then the energy emissiondensity ratio E2 / E1 = 100
In other words – energy concentrates in narrow spaces

EOR Through Electro Treatment
Electric impulses create
gas and steam bubbles,
mainly in spaces filled
with water, since water
conducts electricity much
better than oil
Steam and gas bubbles
Effect 1 – Enhanced oil recovery
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
These bubbles prevent fluid
flow – mainly water – and
reorganize fluid flow routes
Steam and gas bubbles
Effect 1 – Enhanced oil recovery
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
Bubbles are created mainly
in water since impulses go
mainly through water and
viscosity of water is less
than viscosity of oil
Oil and gas bubbles
Effect 1 – Enhanced oil recovery
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
Oil reservoir rock
particles consist of a hard
skeleton with a low
electric conductivity
which is covered by a
less firm component with
a double electric layer
(with better electric
conductivity), which
together with the mud
partially covers rock
particles.
Rock Structure
Effect 2 - intensification
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
Due to the electric pulse,
the energy emission in
the narrow capillaries
significantly increases
local temperature and
intensifies all processes
(creating micro
explosions)
Micro Explosions
Effect 2 - intensification
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
When the temperature
reaches the threshold
value, the mechanical
destruction of the surface
component and mud
occurs in the narrow pore
passages and new oil
paths are opened

1. Enhanced oil recovery in extensive zone
5...10 m
100...200 m
Treatment gives two effects :
2. Intesification of production by reducing clogging in nearest zone
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
1. Enhanced Oil Recovery
By creating gas & steam bubbles ET prevents water flow in reservoir and reorganizes fluid flow routes in it
2. Intensification
By crushing soft layers on top of rock particles ET enlarges the routes for fluid flow
As a result:
- oil production increases- water-cut decreases

Selection of Wells for ElectroTreatment
•More than 50 parameters are used for selecting suitable oil wells for treatment
•A pair of wells is necessary
•If a well suitable for treatment is not close enough, any well (even “empty”) is selected even though no positive results are expected
GLOBAL OIL RECOVERY SYSTEMS,LLC
EOR Through Electro Treatment
Additional Facts
•It is possible to work both on-shore or off-shore
•It is also possible to treat gas fields and fresh water wells
•Electro Treatment is 100 % harmless for the oil field and oil field equipment
•Continuing R&D is leading to even greater results
GLOBAL OIL RECOVERY SYSTEMS,LLC

First measuring and analysis of result
Results shall be followed up at least 12 months after Treatment
Results after Treatment are compared to predicted results without Treatment = additional oil output
Average additional oil output is calculated
Average of additional oil output from a well group defines charge for Treatment
