    Opis:
    The paper presents results of estimation of natural gas prognostic resources in the Polish part of the Rotliegend basin and indicates zones of possible accumulation. Generation potential of Carboniferous source rocks was estimated using the genetic method. Quantity of the free gas introduced into the reservoir was calculated using the differential mass balance method. The final obtained value of the accumulation potential is equivalent to prognostic resources.

    "Rudna" copper mine
    SW Poland
    Opis:
    A block development operation at the "Rudna" copper mine (KGHM Polska Miedź S.A.) encountered a "compressed gas trap" that caused the ejection of fragmented rock material into a drift. Faced with a new threat of gas ejection the mine needed to find methods to identify potential gas concentration zones prior to any further exploration work. Surface seismic surveying was chosen as a widely-accepted standard method of investigating rockmass structure and tectonics and pinpointing natural gas deposits. An area of one square kilometre was selected directly above the ejection site, a 3D seismic survey, known as Duża Wólka 3D, was performed and a survey well S-421A was drilled. The objective was to investigate the overall rock structure, especially the structure of Zechstein and top Rotliegendes formations, as well as to attempt identifying anomalous zones, which could be linked with the gas saturation of Ca1 dolomites, on the 3D seismic image at the P1 level (Zechstein/ Rotliegendes boundary). An interpretation of multi-scenario seismic modelling of the recorded data helped to: – recognize the structure and tectonics of the area, including minor faults cutting through the top-level Rotliegendes formations and floor-level Zechstein formations. Such faults could constitute migration channels for Carboniferous-period gases, – locate zones with nearly zero-reflection amplitude at the surface of the top-level Rotliegendes (P1 seismic boundary), which would suggest a reduction of elastic parameters of the Ca1 dolomite. This reduction could be linked to an increased porosity and fracturing of the dolomite and its saturation with gas (a reduction of the seismic wavelet propagation velocity). Credibility of this interpretation is already partly corroborated by data from wells drilled in the Zechstein limestone by the mine. The paper presents the first in the world attempt to use the surface seismic survey for location of zones with small gas concentration in porous rocks at the Zechstein/Rotliegendes boundary. Such zones should not be identified with gas pools that occur in the Zechstein Limestone (Ca1) in the area of the Fore-Sudetic Monocline.

    Opis:
    Vegetation serves as a universal filter that is capable of protecting the environment from pollution by industrial emissions given the availability of appropriate technical facilities. The aim of this study is to determine the ability of leaves of various species of woody plants growing in the area of sanitary protection zones to accumulate fluorine and to establish the most informative indicators of environmental pollution by its compounds. The object of the study was the species of woody plants growing in the area of protective plantations of a number of enterprises of Zaporizhzhya: Zaporizhzhya Titanium & Magnesium Combine, Zaporizhzhya Aluminium Plant PJSC, Zaporizhzhya Abrasive Plant PJSC, Zaporizhstal PJSC, ‘Zaporizhcoke’ PJSC (KOKS), Zaporizhzhya Ferroalloy Plant PJSC, Zaporizhvohnetryv (‘Vohnetryv’) PJSC, PrJSC ‘Ukrgrafit’ and Zaporizhtransformator PJSC. Under the conditions of sanitary protection zones of enterprises the leaves of woody plants accumulate significantly more fluoride compared to the control specimens. We have established that a gradual accumulation of the element occurs during the vegetation period being the most intense in young leaves. In senescent leaves, the activity of its accumulation begins to diminish. The maximum amount of fluoride was detected by us at the end of the vegetation period. Its highest concentration was found in the leaves of woody plants growing in the forest belt near the Zaporizhzhya Aluminium Plant. According to the level of accumulation of the said phytotoxicant in the leaves of plants growing in the area of sanitary protection zones, industrial enterprises of Zaporizhzhya may be ranked as follows: Zaporizhzhya Aluminium Plant PJSC > Zaporizhzhya Ferroalloy Plant PJSC ≥ ‘Zaporizhcoke’ PJSC > Zaporizhstal PJSC > Zaporizhvohnetryv (‘Vohnetryv’) PJSC > ‘Ukrgrafit’ PJSC> Zaporizhzhya Abrasive Plant PJSC > Zaporizhzhya Titanium & Magnesium Combine > Zaporizhtransformator PJSC. The largest amount of fluorine accumulated by the leaves can be attributed to such tree species as: Catalpa bignonioides, Ailanthus altissima, Acer platanoides, Populus nigra, Armeniaca vulgaris, Tilia cordata, Acer pseudoplatanus, Platanus orientalis, which is a distinguishing characteristic of the sanitary protection zones of various enterprises in the city of Zaporizhzhya. Variations of fluorine accumulation in different experimental plots for the same species of woody plants are expressed in quantitative terms. These plants are capable of being the most efficient at purifying the atmospheric air from gaseous fluoride compounds. The highest coefficient of relative accumulation of fluorine in the leaves is found in the following species of woody plants: Catalpa bignonioides, Ailanthus altissima, Acer platanoides, Populus nigra, Armeniaca vulgaris, Tilia cordata, Acer pseudoplatanus, Platanus orientalis, thus they have a potential to be considered for use as phytoindicators of environmental pollution by the fluorine compounds. The aforementioned coefficient appears to be the lowest in the following species: Morus alba, Elaeagnus angustifolia, Juglans regia and Fraxinus lanceolata.

    Opis:
    The result and interpretation of reservoir tests (DST) are presented in the paper. They were performed in 20 intervals of 17 production wells in years 1995-1997. These wells are located in the Central Carpathians (flysch sand beds) and mainly in the external and internal Carpathian Foredeep (the autochthonous and allochthonous Miocene thin bedded sandstones) and their substratum (mainly carbonates). The basies of the theoretical diagnoses for determining the main types of drainage zones or limits of hydrocarbon accumulations are presented in the form of a short description of the Kappa Company's programmatic procedure (Saphir 202B system). Some diagnostic diagrams for the main reservoir border models are described using the log-log method. Examples of their geological interpretation are also provided.
