Introduction

Global oil recovery systems,llc



• 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

IntroductionGlobal oil recovery systems,llc



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



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.

Treatment continued 24-30 hours

Max 3 km



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

Theory

R2R1



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



These bubbles prevent fluid

flow – mainly water – and

reorganize fluid flow routes

Steam and gas bubbles




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




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



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




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

Effect




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



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



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



What Can Be Done:

•Approximately 20 % of all oil wells worldwide can be treated

•Positive results in more than 90 % of cases

•No risk of harming well

•First results of Electro Treatment can be measured and confirmed within 1-2 months after treatment



What Can Be Done:

•Electro Treatment positively affects 2-5 years of production

•One team can treat 2-3 oil well pairs per week

•Other technologies can be used simultaneously



What Can NOT Be Done:

•Recover “empty” oil wells

•Treat 100 % of oil wells

•Guarantee 100 % positive results, even though we are confident in our results

Treated oil wells

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

Measuring the Results



1. Agreement upon Electro Treatment of 4-6 pilot oil wells

2. Selection of oil wells and expected prognosis

3. Treatment of pilot wells

4. Measurement and analysis of results

5. Determination for further operations
