Balyk river basin for the period 2006–2017 using ArcGIS Pro statistical analysis tools are presented in this article. The information basis of the research is the local environment monitoring data of license areas of Ugra, Khanty-Mansiysk Autonomous Okrug, RF. The research was implemented in two stages. At the first stage, pollution hot spots were revealed basing on the calculation of local Getis-Ord Gi* index for each year. The calculation was made taking into account the mutual location of sampling points and value of the neighborhood. At the second stage hot spots genesis for 12 years was analyzed via modelling space-and-time cube. Clustering time series of hydrocarbons average annual concentration according to the Getis-Ord Gi* indicator made it possible to determine the places of one-off pollution, most likely associated with oil spills, and to track pollutants transportation along the current. The location of the increasing river ecosystem pollution was also determined. The obtained results enable bringing out basic zones of permanent high hydrocarbon concentrations and places of periodic discharges into the river basin.

SUMMARYA characteristic feature of deposits in the weathering crusts is the presence of cracks. To effectively identify such zones, the scattered component of the wave field is used. Specific examples show the mapping of the productive zones of the weathering crust in the field of scattered waves.

SUMMARYThe results of a complex interpretation of the reflected and scattered wave fields are presented to refine the fault-block model and fracture and cavernous reservoirs forecasting of both tectonic and lithogenetic origin. The forecast is based on the original pre-stack migration method -Common Scattering Point Dip (CSPD).
