Infrasonic Geophysical Location of
Anomalies - IGLA technology
It is a technology of direct indication of mineral deposits,
including fluid saturated beds.
IGLA technology is an acoustic method based on allocation
of anomalies in the spectrum of the Depth Infrasonic
Microseismic Wave Field (DIMWF) in the area of a prospective
deposit. Using the saved experience, last development in
hardware and essentially other procedure of measurements and
processing, "IGLA", allows to estimate depth (up to 10 km, error
10-20 %) and thickness of the deposit. The method is applied as
for the dot measurements, for example at distinguishing of
structures revealed by a classical seismic, and for profile and
area measurements, with the purpose of revealing anomalies and
subsequent estimation of their depth.
Main idea: a allocation of anomalies in the spectrum of
the depth infrasonic microseismic wave field detected in the
area above prospective deposit.
Main advantage: using of Earth natural seismicity and
lack of necessity of artificial seismic signal sources
(vibrator), that expands usability of the method to shelf and
hard access areas. IGLA is less expensive and more ecologically
compatible than traditional methods. Equipment: seismometers
SM-3, SM-5, SM-6,
Autonomous recorder of
seismic signals (ARSS),
Autonomous Bottom Seismic
The experience of use is based on forecast and test works of petroleum and gas
prospec- ting by IGLA technologies without definition of depths and thickness of
layers.The tests of IGLA technologies were carried out on many oil and gas
deposits in the different regi- ons of the world (~ 1000 sq. km). These
measurements have confirmed high efficiency the technology in prospecting of
petroleum and gas deposits (Not less than 95 %. From 25 forecasts for drilling
only 1 was unsatisfactory).
Application experience: joint works with the companies - “Geotone", “Tatneft" (Tatarstan),
"Krasnoleninskneftegas" (Russia), "Bukros" and "Plast" (Ukraine), “ONAREP"
(Morocco), "AGIP" (Italy), "TYP" (Jordan), "Tihgsa" (Spain), "Egelados"
(Greece) on oil, gas and water deposits detection.
