Sigor Corporation
Sigor Corporation is seeking to sell its services on
wider scale to increase company's profit and
contribute to the effort to lower gasoline prices by
lowering the cost of oil and gas extraction and
increasing over-all productivity of oil and gas
wells.
History
Sigor Corporation was established in 1991 by
Igor Skakovsky, the current President/CEO, as
an analytical laboratory for applied sciences,
technologies transfer and its management.
During the period from October, 2000 through
October, 2003 Company transformed itself into
worlds pioneering R&D laboratory in rock
mechanics and provider of innovative well
stimulation services.
History
In 2003, after series of Company’s successful
laboratorial tests, plus production stimulation of
103 oil, gas and irrigation wells, Sigor Corporation
acquired 40 years worth of technical data with
agreement of scientific support from its Ukrainian
collaborators.
Same year Sigor Corporation began
commercialization of developed technology by
marketing its services under Trademark of
SWTorpedoTM.
Company Today
Sigor Corporation's high quality well stimulation
services SWTorpedoTM (Shock Waves Torpedo)
offers cost-effective recovery of hydrocarbon by
providing significant, stable-over-time spatial
changes in the rock permeability and predictable
increase in productivity for more then 300%.
Company Today
As all members of SWTorpedoTM family
SWT-GUARANT, SWT-OPTIMUM and SWT-ECONOM
uses dilatant technology and is designed
individually for each well to increase permeability
of the producing interval.
SWT-OPTIMUM service saved over USD 20,000
when stimulating limestone of the open-hole gas
well Asher #8 in Bell County, Kentucky.

Fundamentals of Dilatant Technology
Dilatancy is a permanent deformation registered
in rocks that are subjected to non-uniform
dynamic stress. As the rock-volume changes,
porosity can increase up to 60% and permeability
increases 200% or more, as a result of the
microfracturing or cracking that have been
measured in laboratory experiments using core
samples and in the field tests by implementing
SWTorpedoTM services.
Dilatancy
Schema A: Granules of the sores rock before
stress.
Schema B: Rock-volume have changed under
dynamic stress.
Dilatancy
Dilatancy is the increase in volume of a granular
substance when its shape is changed, because of
greater distance between its component particles.
Dilatancy
Factors that affect deformation are:
 Dilatancy
 Grain crushing
 Size of the grain
 Thermal characteristics
 Spatial variations in bed strength
 Decoupling
The Tool
SWTorpedo Tool will be
designed using the rock’s
characteristics received
from the client by placing
high explosives strategically
in the tool and securing
appropriate timing for the
detonation of each charge.
Figure 2 Schematic view of internal design
Tool’s effect on the rock
High explosives such as TNT, HMX or RDX are
strategically placed in the Tool and detonated in rapid
succession to generate multiple shock waves that in
return creates changing in time stress state, which
approaching uniaxial compression and perfect shift.
At this point fast growing increase in volume of rock
can be observed, even though active forces are still
working in compressive regime.

When Tool is detonated explosive forces create pressure of 10 ...10
МPa per second. Successive shock waves prolong the stress and
initiated fractures will be multiple. The area of Dilatancy or microfractures is on average 6 times larger than an area of radial fractures
How SWTorpedo is fielded?
1 Selected well must be shut in
and prepared in the same
manner as it would be for
perforation. That includes:
tubing and rod removal
2 Wireline truck with an
operating crew (electrical
wireline is required)
3 Depth of productive interval
which plan to be treated must
be confirm and cable-line
must be marked.
How SWTorpedo is fielded?
4 Water truck with and operating crew
To avoid stress on wireline, water, solution or other
fluid for depressing the well must be pumped in the
well up to at least 90 feet above the interval at which
Tool will be detonated. Concentration of the solution,
its level and/or water level in the well must be
calculated based on the pressure in the formation.
How SWTorpedo is fielded?
Reusable torpedo’s head
must be attached to a cable
head by the female adapter
with 1 7/16 in. thread

How SWTorpedo is fielded?
Electrical detonator must
be wired and connected
to a detonative cord
