Efficiency of technology
If you are not satisfied with standard geophysical methods, then you need something more!

Since 2005 to 2010 JSC УGradientФ completed 126 projects with total area of 1133.5 sq. km.

The efficiency rate of the LFS technology amounted to 85.3%

95 wells were drilled by the Low-Frequency Seismic Sounding interpretation results. 81 wells have confirmed the forecasting. 28 wells produced hydrocarbons from the carbonate reservoirs, and 35 wells produced hydrocarbons from the terrigenous reservoirs.
