The republican scientific seminar in the field of Earth sciences, dedicated to the connection between mud volcanism and hydrocarbon deposits was held in the ANAS Institute of Geology and Geophysics (IGG).

Director of the Institute of Geology and Geophysics, academician Akif Alizadeh opened the seminar.

Then the head of the department of oil and gas geophysics of the Institute of Oil and Gas of ANAS, Doctor of geological-mineralogical sciences Namaz Yusubov made a report on “Is there a connection between mud volcanism and hydrocarbon deposits? (on the example of the South Caspian basin)”. The scientist spoke about the role of seismic survey in research aimed to understanding the geodynamic processes occurring in the South Caspian basin, rich in oil and gas fields. N. Yusubov said that wave fronts reflected in the geological environment inform about synchronous or asynchronous geological events.

The reflections from layers and the other elements of the Earths crust are represented as seismic horizons in time sections. The seismic time period is the tectonic disturbances in the geological section of the study area, the boundaries of lithofacial variations, folds of different shapes, eruptive channels of mud volcanoes, etc. The time section is the image of vertical plane passing through the geologic section.

The reporter also informed about the structure of the sedimentary layer in the depressions, obtained by the method of seismic survey of reflected waves. The mechanisms of mud volcanism and oil and gas fields are considered as part of a single hydrodynamic system.

Based on a comprehensive interpretation of visual geological and geophysical data (seismic and well geophysical surveys) and seismogeological modeling, it may be assume the direct participation of eruptive channels of mud volcanoes in the hydrocarbon deposits formation.

At the end of the report, Namaz Yusubov answered numerous questions. The report was widely discussed. Based on the data obtained, it was decided to conduct joint comprehensive research.
