The aim of the research is a complex analysis of the eastern part of the Baltic Basin (northern Poland) using all available geological and geophysical data to reconstruct the basin evolution. Several elements are significant, e.g. facies extent, subsidence analysis, structural evolution, to obtain better understanding of processes which influenced the basin development. As a result, potential reservoirs will be identified.

The Baltic Basin is situated at the western margin of the East European Craton. It consists of almost complete stratigraphic succession - from Neoproterozoic to Quaternary. The most important units for petroleum exploration are Middle Cambrian (Paradoxides paradoxissimus) sandstones, organic rich shales of Upper Cambrian-Lower Ordovician (Piasnica shale formation) and Upper Ordovician-Lower Silurian (Sasin and Paslek shale formations).

For the analysis, several tools will be combined: from sample and data collection (drill cores analysis, thin sections, seismic data and well logs), through the analyses composed of SEM-EDS, EMPA, to the final model preparation, using G&G software – Move 2013.1, RockWorks15 for basin visualization and modeling, Sedpak for dynamic modeling of basin filling and OpendTect 4.2.0 for seismic interpretation.

This part of the Basin is currently intensively explored for shale reservoirs by international companies. The studied area suffers from lack of wells, new data and publications. A few old boreholes, well logs and poor seismic acquisition have resulted in weak recognition of the eastern part of the basin. What is more, the data from the study area haven’t been subjected to modern basin analysis. Hence, the exploration requires more present research.
