Modern geochemical technologies to identify the hydrosphere oil pollution sources
Some methodical approaches to identification of the subaerial hydrosphere oil pollution sources at the oil fields of Perm-Kama region are considered. It is revealed that the methods of spectral-chromatographic profiling of oils composition and aqua-bitumens allow identification of not only the sources but also the time of subaerial hydrosphere oil pollution. The informative nature of the surface gas-geochemical probing by "ECOPROBE-5" express gas analyzer when mapping oil pollution zones and identifying defective wells that are characterized by activation of formation fluids' vertical cross-flows is proved.
