Observing the phenomena of paragenesis, subvertical, zonary annulars, geo-physical and geochemical areas provides possibility to explore the accommodation of oil-water suppression selvages of petroleum deposits, using onshore geochemical and geophysical methods and equipment-specific, new approach, concerning producing fields and peripheral areas. The article deals with identification of common factors of changes in geo-physical and geochemical fields above hydrocarbon reservoir and outside it.
Materials and methods
Geophysical and geochemical methods, statistical analysis.
Results
The complex parameter map of probability of oil bearing object was constructed, using statistical analysis and modeling of geophysical and geochemical parameters. The contour of the anomalous region coincides with the boundaries of the deposit.
Сonclusions
Application of geophysical, geochemical and statistics research allows to delineate hydrocarbon reservoirs.
