    Opis:
    The upper Cambrian-Silurian Piaœnica, Sasino, Udal and Pelplin formations and the Jantar Member include the most organic-rich lower Paleozoic sedimentary rocks in the Baltic-Podlasie-Lublin Basin in Poland. These rocks vary significantly in terms of vertical and lateral organic matter distribution. Generally, the siltstones, mudstones, claystones and shales are characterized by TOC values from 0.1 to as much as 17.4 wt. %. Typically, the maximum TOCvaluesreachabout9wt.%.Rock-Eval,organicmatterpetrologyandbiomarkersdataclearly indicate dominance of type II kerogen. Thermal maturity of organic matter of these rocks is variable and depends mainly on the burial history and depth. In the western slope of the East-European Craton the petroleum prospective formations are located throughout the whole spectrum of thermal maturity zones, from the immature zone (eastern margin of the formations occurrence), through the oil, condensate and gas windows, to the overmature zone dominated by exhausted source rocks in the western margins of the study area.

    Opis:
    This paper describes a regional overview of selected Central and Eastern European sedimentary basins which hold the unconventional potential for shale gas and shale oil exploration that have attracted interest in the last few years. Organic-rich fine-grained rocks like black and dark-grey shales, mudstones and claystones with varying ages from Cambrian to Miocene are distributed very irregularly across Europe. A long- -lasting, dynamic geological evolution and continuous reconstruction of the European continent resulted in the formation of many sedimentary basins. In some basins, biogeochemical conditions favoured preservation of accumulated organic-rich deposits and led to the generation of hydrocarbons after burial and reaching appropriate maturity levels. Even though shale gas and shale oil exploration in Europe is still in its infancy, shale formations were analyzed before as the source rocks in conventional petroleum systems. Parameters that were used to describe source rocks e.g.: total organic carbon, maturity, thickness, depth of occurrence and areal extent, can indicate preliminary potential for shale gas exploration and allow estimating first resource values. Currently the most intense shale gas exploration takes place in Poland where over 42 wells have been drilled and over 100 concessions for unconventional hydrocarbon exploration have been granted. Upper Ordovician and Lower Silurian shales at the East European Craton (Baltic and Lublin-Podlasie Basins) are the major targets for unconventional exploration in Poland. In Central and Eastern Europe, evaluation of the unconventional potential of gas-bearing shale formations is carried out also in Ukraine, Lithuania, Austria, Czech Republic, Hungary, Romania, Bulgaria, Moldavia and the European sector of Turkey. Despite the fact that each shale rock differs from another by geochemical, petrographical, petrophysical, mechanical and other parameters, some similarities can be seen such as marine type of depositional environment with the predominance of type II kerogen or specific organic matter content. Recoverable resources of shale gas throughout Europe are believed to be as large as 17.6 bln m3 and Poland, Ukraine, France with United Kingdom are thought to have the greatest resources.

    Opis:
    The paper presents the characteristics of prospective zones identified for the first time within the lower Palaeozoic shale formations occurring in the Baltic-Podlasie-Lublin Basin and within the Carboniferous shale, sandstone, and mixed shale-sandstone complexes (the so-called hybrid complexes) in the basin of south-western Poland. The lateral and vertical ranges of these zones are determined based on specific criteria using the results of various research methods and analyses, i.e.: stratigraphic, sedimentological, mineralogical, petrological and geochemical of organic matter, petrographic and petrophysical, including interpretation of well logs. Archived geological materials and those coming from the boreholes drilled recently in the concession areas were also used. Four prospective zones have been distinguished in the lower Palaeozoic of the so-called shale belt: SP1, SP2, SP3 and SP4. The most prospective area for the occurrence of unconventional hydrocarbon deposits in shale formations is the Baltic region – the Łeba Elevation, where there are all four perspective zones, only partially covering the range of potentially prospective formations. In each of these zones, both liquid and gas hydrocarbons can be expected in this area. Due to the low percentage of organic matter, the lowest hydrocarbon generation potential is attributed to the Lublin region. However, the low values of this parameter are compensated by other parameters, i.e. the considerable thickness and lateral extent of zone SP4 corresponding partly to the Pelplin Formation. In the Carboniferous rocks of south-western Poland, seven prospective zones have been distinguished in four borehole sections. Four of them are “tight” zones in compact sandstones, while the other three zones represent a hybrid type in complexes with mixed lithology. No prospective zones have been defined in complexes with homogeneous shale lithologies. Determination of lateral extents of the identified zones has not been possible due to the scarcity of data on the geological structure and stratigraphy of the Carboniferous succession in the study area
