"Less drill – more produce – this is VSP motto"

– these words belong to Evsei Iosifivich Galperin who is the vertical seismic profiling (VSP) founder.

The organization implements 3C VSP processing and interpretation. The rich experience in VSP data processing and interpretation is accumulated by our employees.

The VSP allows solving the range of important geological problems:

  • The receaching of wavefield forming within medium. Concurrently, the waves of various types and classes (direct, reflected, multiples, refracted, longitudinal, shear, mode-converted), excitated by the source and formed at the subsurface irregularities, are extracted, traced and studied (see Fig. 1 and 2);
  • The receaching near-well and inter-well space on the considerable distances from the well and wide range of geologic conditions, not only in the bored interval of depths but also beneath the well bottom (see Fig. 3 and 4);
  • Obtaining the interval, layer and average velocities of longitudinal and shear waves (Fig. 5), studying the complex properties: velocity parameter, Poisson ratio;
  • The exact stratigraphic calibration of reflections (Fig. 6) and tying well log, VSP and CDP data.
