EXECUTIVE SUMMARY


Azerbaijan contains numerous mud volcanoes which emit breccias, water, gas and oil films. The study of mud volcano emissions yields useful imformation about sedimentary deposits at the depths which are not available from conventional drilling.


The proposed report contains the results of new research compiled by a team of scientists in the Geology Institute of Azerbaijan Academy of Sciences and the BP/Statoil Alliance. This research describes 16 typical mud volcanoes from three oil-gas regions: Shemakha-Gobustan, Lower Kura and Apsheron. The report consists of four volumes and contains:


General information regarding mud volcano evolution including:

  • recent maps of mud volcano activity in Azerbaijan (onshore and offshore) constructed on topographical, geological and tectonic bases corrected with the use of satellite imagery;
  • maps of heat flow distribution in Azerbaijan prepared from satellite surveys through time;
  • regional tectonic profiles illustrating the structure of mud volcano areas;


complex data on each of the 16 mud volcanoes, including the information on geomorphology, tectonic structure, geological situation, temperature regime, the results of isotope and geochemical research of gas, oil, water and organic matter, and the mineralogical-geochemical analysis of breccias.


The report is well illustrated by coloured photos of the studied mud volcanoes.
