Conclusions

The constructed model is of great importance in the study of the deep structure and oil and gas zones of these deposits with a complex structure, the detection of industrial fields and the correct choice of deep wells in search and exploration.

As a result, based on the model of the deep structure of the Lower Kura depression is possible to forecast the future and evaluation of oil and gas facilities in view of geodynamics, temperature and pressure, seismic, petro physical and lithofacies factors. Oil generation from the Lower Eocene presumed source rocks commenced at the end of Pliocene and continues at present at depths between 6000 and 9000 m; and peak oil generation is taking place at depths between 7000 and 8000 m.

This study confirms earlier hypothesis that oil generation and preservation in the depression must extend to deeper levels in the study area; owing to low temperature gradient and high sedimentation rate. Accordingly, we conclude that future petroleum exploration activities may safely involve deeper horizons
