The technology was tested with model data. The technology was used for computing the optimum parameters of a logarithmic sweep-signal for the Dobryanska area, the Bilche-Volytska zone of the Perikarpathian depression. A method for adaptive optimum weighted stacking of common midpoint gather was advanced and tested with a field data set. The method is based on using a more complicated model of the multichannel seismic record. A method for eliminating source-generated noise from common midpoint and common shotpoint gathers was advanced and tested with synthetic and field data sets. The method takes advantages of combining a singular value decomposition and previous special linear transformation of seismogram sectors containing intense source-generated noise. A method is developed and tested with synthetic data sets for calibrating AVO-anomalies with VSP data. The method contains migration of waves from the well to a boundary under study, calculation of the reflection coefficients and then approximation these coefficients by a line, in order to determine the AVO-intercept and AVO-gradient A field of application is geological prospecting.
