Abstract


This article provides general information about the geological structure of South-Piltun oil and gas deposit as well as it considers the role of mud volcanism and its scientific-practical significance in order to clarify factors of oil and gas deposit formation for South-Piltun further development.Petroleum expert’s wide interest and thematic justification connected with the mud volcanism and hydrocarbon deposit geodynamics correlation are associated with new scientific disciplines implementation and development in oil and gas geology and geochemistry, as well as with the oil and gas fields upstream methods in view of the previous achievements in a complex of Earth Sciences. Currently, without any doubt the elision systems (especially mud volcanism) are associated with hydrocarbon saturation (especially taking into account hydrocarbon fluids migration) and are abundant in the areas where tectonic activity is expressed as the folding. In addition to clarify the geological structure characteristics of the Piltun-Astokh field (South-Piltun area) the main aim of this article is defining the connection between mud volcanoes and Nutovo subhorizon hydrocarbon deposits, revealing of volcanic confinedness to the oil and gas deposits geodynamic conditions, as well as the definition of the territory tectonic structure features.Taking into consideration the previous years’ experience and data obtained next challenging tasks should be formed, the systematization and integration carried out suggest that fault different forms distribution nature and some other factors are responsible for direct correlation between mud volcanism and oil and gas fields geodynamics.
