In the face of complicated seismic and geological conditions in hydrocarbon-field area of Polish Carpathians there is a problem of accurate localization of hydrocarbon traps. In this case, cartographical documentation based on cartographical survey and core data analysis has been great significance.

The study object of this project is the Tyrawa Solna Antycline. At the culmination of this structure, a shallow oil field in the Kliwa Sandstone (Lower Oligocene) was found in the ’80 of 19-th century. The anticline axis, secondarily folded and dislocated, dips into the depocenter of the Skole Unit Synclinorium, in which generation kitchen was contoured (SPI in the range of 8 – 20 t HC/m2). Because the Kliwski Sandstones a main oilbearing horizons in adjacent Wankowa and Lodyna oil fields, there is a possibility of existing of the potential hydrocarbon traps structural-lithological type in near-fault areas.

A principal element of the project is to detail older geological maps in the purpose of carthographical documentation of : tectonics of the anticline hinge and faults dislocate it, changes of thickness of strata that build this anticline, in association with reservoir properties of sandstones.

Interpretation of field study results in the form of geological cross-sections and structural maps of potential reservoir series will be related to the actual recognition of subsurface structure and results of petroleum system modeling.
