Summary:
In more recent times there had been an increase geoecological investigations related to the pollution of the geological environment with oil and oil products. This is due to the widespread distribution oil contamination, considerable mobility and toxicity of its individual components. As the experience of geoecological investigations has shown, the decisive influence on the formation and spread of hydrocarbon contamination has the features of the geological and hydrogeological structure of the upper part of the section. In order to detect such near-surface features it is necessary to carry out detailed geophysical researches as a cheap and effective search tools. Depending on specific natural and man-made conditions and tasks, a rational set of ecological and geophysical methods in the study of pollution of the geological environment with petroleum products includes: vertical microelectrical sounding, microelectric profiling, SP method, seismic (Correlation Refraction Method), georadar, oxidation-reduction potentials, gasometric, thermometric and IR surveys, which can be complemented by well logging measurements. The base of the complex of geophysical methods, as a rule, is the microelectrical sounding. There is an illustrative example of the successful appliance of geophysical surface complex for studying.
