ABSTRACT: Hydrocarbon Potential Evaluation of the Dniepr-Donetsk Basin by Its Thermal Modeling and Burial Analysis

This research is focused on reconstruction of burial history and thermal modeling of the Dniepr-Donetsk Basin (DDB), the largest and deepest Devonian rift basin in Ukraine and Europe.

Cumulative production and remaining reserves of hydrocarbon in the DDB are estimated as 170*106 t of oil and condensategas and 980*109 m3 of natural gas.

The objectives of this research are:

1. Reconstruction of the burial history based on 66 stratigraphic sections, distributed throughout the basin, composed on seismic and well log data.

2. Modeling of the paleothermal conditions based on present-day temperatures and heat-flows measurements.

3. Thermal maturity modeling to determine the time petroleum generation and accumulation.

To accomplish these objectives the following procedures will be carried out:

1. Analysis up to 10 CDP regional seismic sections and about 70 well logs.

2. Study temperature and heat-flow values from well and coal mines.

3. Collect core and surface samples for vitrinite reflectance in oil immersion measurements. Previous vitrinite reflectance in air range from 8.0 to 8.5% in the central part of basin and increase significantly towards the margins and achieve 1214%.

4. Apply these data to the modeling of burial history and thermal maturation.

Anticipated results will enhance our understanding of the DDB evolution in respect its thermal and source rock history.
