    Opis:
    The aim of this study was to use the structural restoration technique to verify the correctness of the structural and palaeothickness maps created during the BLUE GAS Project. On the basis of well data as well as refined structural and palaeothickness maps of Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic and Cretaceous horizons, a cross-section running across the Baltic Basin, the Mazury High and the Podlasie Basin was created. During the restoration process, the effects of compaction and fault activity were removed sequentially. The amount of erosion was estimated on the basis of the corrected palaeothickness maps. The resulting restoration is geologically reasonable and therefore both the structural and palaeothickness maps should be regarded as reliable. The reconstruction also allowed reproduction of the initial geometry and thickness of the Cambrian–Devonian strata and the recognition of three main episodes in the evolution of the sedimentary cover of this part of the East European Craton. The first episode was related to the deposition of the Lower Palaeozoic (up to the Lower Devonian) sedimentary complex on the relatively flat surface of the East European Craton edge. During the second episode, lasting most probably to the Permian, the Baltic and Podlasie Basins subsided significantly. The amount of subsidence was much higher in the Podlasie Basin. The third episode is related to the deposition of the almost flat-lying Mesozoic–Cainozoic complex.

    Opis:
    A set of geological maps and geological cross-sections was prepared to document the geological setting of sedimentary basins developed on the western slope of the EEC and adjacent areas to the west. On the basis of these data and literature on the subject, the evolution of the sedimentary basins in the study area was reviewed, with special emphasis on the Ediacaran–Lower Palaeozoic basin. The basin originated during late Ediacaran rifting, related to the latest stages of breakup of the Precambrian super-continent Rodinia/Pannotia, associated with large-scale igneous activity. The rifting ultimately led to the formation of the Tornquist Ocean and subsequently, during the latest Ediacaran to Middle Ordovician, the SW margin of the newly formed Baltica became a passive continental margin. The upper Cambrian depocentre in the Biłgoraj-Narol Zone and the Łysogóry Block tentatively is interpreted as a small, narrow foredeep, related to the docking of the Małopolska Block to the western margin of Baltica. From the Late Ordovician through the Silurian, a gradual change to a collisional tectonic setting is observed across the entire SW margin of Baltica, as well as in the zones adjacent to it from the west, which together became the site of development of the extensive Caledonian foredeep basin, related to the convergence and collision of Avalonia and Baltica. The oblique character of the collision resulted in a prominent diachronism in the development of the foredeep basin. This refers to the initiation of basin subsidence, the starved basin phase, the main phase of rapid subsidence and supply of detritus from the west, and the termination of basin development. The Early Mississippian (Bretonian) phase of uplift and erosion and, to a lesser degree, also the Late Pennsylvanian one significantly affected the structure of the western EEC. During the Mississippian, extensive magmatic activity took place at the SW margin of East European Craton, in the region referred to here as the Baltic-Lublin Igneous Province.

    potential source rock for hydrocarbons
    Opis:
    In the present contribution we examine possible role of deposits of the Białopole, Lublin, Włodawa and Mazowsze Forma-tions (uppermost Ediacaran to lowermost Cambrian), as well as their presumed lateral equivalents, developed in the Lublin-Podlasie region as a potential source rock for hydrocarbons. The analysed sediments contain marine kerogen of algal and cyanobacterial ori-gin, i.e., predominantly oil prone. In some parts of the analysed area recent TOC could reach 0.65%, however, primary TOC could be significantly higher, as it is indicated by relatively high maturity of the hydrocarbons. Quality of potential source rock increases towards SW. The analysed potential source rock could be, at least partly, responsible for oil and gas shows, commonly observed in the Lower and Middle Cambrian sandstone horizons.

    Opis:
    Three-dimensional, structural and parametric numerical modelling was applied to unravel the unconventional hydrocarbon potential of a W-dipping, Lower Palaeozoic mudrock succession, which subcrops for some 700 km in the Baltic, Podlasie and Lublin basins across the SW margin of East European Craton in Poland. Input data comprised structural and thickness maps of Ordovician and Silurian strata and the results of thermal maturity (mean vitrinite-equivalent reflectance, % Ro) and total organic carbon (TOC, % wt.) modelling. A new, spatial interpretation of vitrinite-reflectance variability indicates that the regional, W-increasing thermal maturity pattern breaks into a series of domains, bounded by abrupt maturity variations. In total, 14 tectono-thermal domains were recognised and their boundaries traced to known and inferred faults, mostly of NW‒SE and NE‒SW orientations. On the basis of a combination of thermal maturity and total organic carbon levels (0.6% > Ro<2.4%, and TOC >1.5% wt.), good-quality, unconventional reservoirs can be expected in the Sasino Formation (Caradoc) and Jantar Formation (early Llandovery) in the central and western Baltic Basin. The Jantar Formation also is likely to be prospective in the western Podlasie Basin. Marginal-quality reservoirs may occur in the Sasino and Jantar formations within the Podlasie and Lublin basins and in the Pasłęk Formation (late Llandovery) across all basins. Poor- to moderate-quality, unconventional reservoirs could be present in the Pelplin Formation (Wenlock) in the Lublin and southern Podlasie basins. In spite of a considerable hydrocarbon loss during multiphase basin inversion, the Ordovician and Silurian mudrocks still contain huge quantities of dispersed gas. Successful exploitation of it would require the adoption of advanced fracking methods.Lower Palaeozoic, shale gas, shale oil, Baltic Basin, Lublin-Podlasie Basin, total organic carbon, thermal maturity, structural-parametric model.

    sequence stratigraphy
    Opis:
    Sequence stratigraphy approach has been applied for the Neoproterozoic to Cambrian sedimentary fill of the Lublin–Podlasie Basin; the main goal of the study is to discriminate between eustatic and tectonic control of the observed sequence development. The Neoproterozoic and Cambrian sedimentary fill of the Lublin–Podlasie Basin is subdivided here into two second-order depositional sequences, separated by a basin-wide unconformity. The lower sequence A is poorly recognised. It is presumably of the early Neoproterozoic age, and is characterized by continental to costal shallow marine developments. Sequence B comprises the (late?) Neoproterozoic to Middle Cambrian. The lowermost part of the sequence B is composed of a lowstand systems tract (LST). At that time a low relative sea level was con-trolled by regional thermal doming, followed by rapid clastic and volcanogenic deposition, with rate exceeding that of subsidence of extensional grabens. During the latest Ediacaran, a transgressive systems tract I (TST I) developed. Increase of the rate of relative sea level rise was induced by a transition from syn-rift to post-rift subsidence. During the development of a following highstand systems tract I (HST I), significant sediment supply exceeded the rate of basement subsidence, causing progradation of shoreline. The next higher up-section transgressive system tract (TST II) is characterized by a gradual rela-tive sea level increase and reflects continued thermal sag phase of the Lublin–Podlasie Basin. Development of the TST II was coeval with a global transgression and controlled mainly by eustatic sea level rise. The beginning of the Middle Cambrian corresponds to the development of a HST II, controlled by a low rate of increase of the relative sea level, even if it was coeval in time with the Hawke Bay regression. The HST II is therefore interpreted here as controlled by local tectonic processes, superimposed on continued post-rift thermal subsidence of the passive margin.

    Opis:
    The following work presents investigation of possible drilling of overburden rocks, right above the gas reservoir, in shale rock formations with potential application of rotary-percussion drilling method in Podlasie Basin region. Extensive description of lithology of shale rocks together with their age, maturity of the organic matter and thickness of particular layers have been presented. Due to different thickness of formations, the depths of layers are not indicated, as it would be too big of approximation. Variously scaled and averaged thickness of particular formation layers was given in order to maintain maximum transparency of the paper. It should be noted that the formation rocks of the Devonian as well as Carboniferous period do not occur in all profiles of the Paleozoic period of the Podlasie Basin but only in the south-western part of the basin. Locally occurring (i.e. on the south-eastern border of the Podlasie basin) layers of the Devonian and Carboniferous period were omitted. A stratigraphic profile with preserved proportions between the average thicknesses of particular formation layers was constructed and presented in latter part of the research paper. The research carried out in this paper was complemented with estimates of Polish shale gas resources. The Baltic Basin region is by far most prospective area for shale gas exploitation when it comes to documented as well as undocumented resources. The areas of Podlasie as well as Lublin Basins are second and third most rich areas of this resource. Percussion-rotary drilling method enables for much higher penetration rates using similar weight on bit and rotational speed as in standard rotary drilling method. Following papers answers questions such as: under what conditions application of percussion-rotary technique is possible or what drilling fluids are the most suitable for such method. The percussion-rotary drilling method not only guarantees faster drilling but also leaves borehole much more straight and without unnecessary dog legs. Drilling rig and down hole equipment used for percussion-rotary drilling method takes much less space in comparison with standard rotary rigs for deep drilling and could be potentially implemented for drilling shale gas wells in Podlasie Basin region.
    Poniższa praca przedstawia badania nad potencjalnym wykorzystaniem metody udarowo-obrotowej w celu wiercenia formacji skalnych występujących tuż nad pokładami złóż gazu łupkowego w rejonie basenu podlaskiego. W poniższym artykule została przeprowadzona analiza skał łupkowych wraz z ich wiekiem, dojrzałością materii organicznej oraz miąższością poszczególnych warstw. Na skutek dość zróżnicowanej miąższości formacji skalnych, głębokość zalegania warstw nie została określona z powodu dużego błędu przy uśrednieniu ich wartości. Wyskalowane oraz uśrednione miąższości zostały przedstawiono w celu utrzymania spójności i przejrzystości pracy. Należy nadmienić, że formacje skalne z okresu dewońskiego oraz karbońskiego nie występują we wszystkich profilach z okresu paleozoiku basenu podlaskiego, a jedynie w jego południowo-zachodnich częściach. Pominięto lokalnie występujące (tj. na południowo-wschodniej granicy) warstwy dewońskie oraz karbońskie. Profil litostratygraficzny z zachowanymi proporcjami pomiędzy średnimi miąższościami poszczególnych warstw skalnych został skonstruowany oraz przedstawiony w końcowej części pracy. Badania w poniższym artykule zostały dodatkowo uzupełnione danymi szacunkowymi zasobów gazu łupkowego na terenie Polski. Obszar basenu bałtyckiego jest obecnie najbardziej lukratywny pod względem wydobycia gazu ze skał łupkowych z powodu dużej ilości udokumentowanych oraz jeszcze nierozpoznanych złóż tego surowca. Obszary basenu podlaskiego oraz lubelskiego są drugie oraz trzecie w kolejności pod względem ilości zasobów gazu łupkowego na terenie Polski. Metoda udarowo-obrotowa pozwala na dużo szybsze zwiercanie formacji skalnych przy użyciu podobnych parametrów mechanicznych takich jak nacisk na świder i prędkość obrotowa niż przy standardowym procesie wiercenia metodą obrotową. Poniższy artykuł odpowiada na pytania takie jak: w jakich warunkach możliwe jest wiercenie metodą udarowo-obrotową oraz jakie rodzaje płuczek wiertniczych są najbardziej odpowiednie do wiercenia taką techniką. Metoda udarowo-obrotowa zapewnia nie tylko dużo większy postęp wiertniczy, ale również dużo mniejsze odchylenia od osi otworu oraz zapobiega nagłym zmianom kierunku podczas procesu wiercenia. Wiertnica oraz osprzęt zapuszczany do otworu stosowany podczas wiercenia metodą udarowo-obrotową zajmuje znacznie dużo mniej miejsca w porównaniu z głębokimi wierceniami konwencjonalnymi metodami. Dzięki wspomnianym zaletom metoda udarowo-obrotowa może zostać potencjalnie wykorzystana przy wierceniu otworów za gazem łupkowym w obszarze basenu podlaskiego.

    reservoir characteristics
    Opis:
    In the Baltic-Podlasie-Lublin Basin, four potential lower Paleozoic shale reservoirs are identified: the Piaśnica, Sasino and Jantar formations, as well as the Mingajny shale. These units were diachronously deposited during the starved stages of Caledonian foredeep basin development, in the course of rising or high eustatic sea level. Across most of the basin, the shale formations analysed are saturated with light oil and condensate, and they are buried to depths of 2300-3500 m. The shale reservoirs reach the wet gas window at burial depths of 2800-4000 m, while dry gas accumulations occur at depths exceeding 3500-5000 m, except in the Biłgoraj-Narol Zone. The shale analysed might be generally classified as a moderate to low quality, and locally high quality, unconventional reservoir. Within the shale net pay zones, the average TOC content is 2-5 wt.% TOC. The exceptions are the Piaśnica Formation, for which this is 5-12 wt.%, and the Mingajny shale, which is TOC-lean (1.4-1.7 wt.%). The thickness of the shale net pay intervals in the most favourable locations, mainly on the Łeba Elevation, generally reaches 20 m, and locally exceeds 35 m. The shale reservoirs are saturated with hydrocarbons of good quality. Their permeability is low to moderate, often in the range of 150-200 mD, while total porosity average per borehole is commonly exceeds 6 %, reaching up to 10% at maximum, which might be considered as moderate to good. The clay minerals content is moderate to high (30-50%), and geomechanical characteristics of the shale formations are intermediate between brittle and ductile. No overpressure occurs in the basin, except for a dry gas zone in the SW Baltic Basin. In the Biłgoraj-Narol Zone, and to a lesser degree also in the Lublin region, pronounced tectonic deformation significantly limits shale gas/oil potential. Among 66 exploration boreholes drilled in the basin so far, only 5 were lateral boreholes with representative production test results. Hydrocarbon flow from the best boreholes was low to moderate, equal to 11.2 to 15.6 thousand m3/day for gas, and 157 bbl/day (~21.4 ton/day) for oil. There is, however, high potential to improve production flow rates, connected with the fracturing of two net pay intervals at one time, as well as with significant technological progress in the exploitation of shale basins during the last 5 years. Commercially viable production might be achieved for a single borehole with estimated ultimate recovery exceeding 30-50 thousand tons of oil, or 60-90 million m3 of gas.

    Opis:
    In western and central parts of the Podlasie-Lublin Basin, Upper Ordovician-Lower Silurian mixed siliciclastic-carbonate section is dominated by fine-grained sediments (claystones, mudstones), which are passing into more carbonaceous ones towards the east. In this region, subsidence was controlled by flexural bending of the East European Craton margin. Sedimentological analysis of drill cores revealed that deposition of those fine-grained sediments originated from suspension and traction currents. Amount of oxygen plays important role in the rock record (Fig. 1) whereas occurrence of pyrite is significant for determinations of sedimentary conditionsion, also in terms of sea level changes (Fig. 2). The rocks display abundant sedimentological structures such as current ripples, wave ripples, hummocky cross-stratification (HCS), graded beds, water escape structures, soft sediment deformation and scours (Fig. 3). The rocks are also characterized by predominance of wave ripples, common scours, graded beds and soft sediment deformations whereas current ripples, water escape structures and HCS are rather rare. The most frequent of the ichnofacies elements include unlined, rarely branched Planolites, which represent Scolithos, Cruziana and Zoophycus ichnofacies. The size of elements of Planolites ichnofacies appears dependent on environmental conditions and ranges from 0.5 mm to 15 mm. Chondrites, Anconichnus, Helminthopsis and Teichichnus, very important environment indicators, are present but not that common (Fig. 4). Textural analyses along with the records of diagenetic features made it possible to distinguish a succession of stratigraphic parasequences (Fig. 5). Early carbonate cementation appeared important, especially in the case of suble or invisible changes in grain size. On the basis of the obtained results, depositional environment of fined-grained sediments in the Podlasie-Lublin Basin was interpreted as a wave-dominated shelf with turbidite episodes. Detailed sedimentological observations are crucial for definiting facies types and prediction of their distribution, but also for tracing the most organic-rich units in the sedimentological profile, as the basic in terms of gas shale prospects. Apparently monotonous fine-grained sediments (claystones and mudstones) are shown to be in fact miscellaneous.

W sukcesji górnego ediakaru wyróżniono osiem jednostek litostratygraficznych, w tym siedem formacji i jedno ogniwo. Podstawą wydzielenia jednostek było zróżnicowanie makroskopowych cech litologicznych w profilach z ediakaru. W charakterystyce jednostek litostratygraficznych zawarto historię ich nazewnictwa, kryteria zdefiniowania jednostki, opis, stratotypy i hipostratotypy, granice, chronostratygrafię, skamieniałości, interpretację genetyczną, miąższość, rozprzestrzenienie regionalne i odpowiedniki litostratygraficzne na obszarach sąsiednich.
    The paper presents a formalized lithostratigraphic scheme of the Ediacaran clastic and volcanogenic deposits from the Lublin-Podlasie sedimentary basin, located in eastern and south-eastern Poland. The upper Ediacaran succession consists of eight lithostratigraphic units, including seven in the rank of formation, and one member. The basis for the identification of the units was the variability of macroscopic lithological features in the Ediacaran sections. The characterization of the lithostratigraphic units provides the history of their names and criteria for defining the units, and their description. The stratotypes and hypostratotypes, boundaries, chronostratigraphy, fossils, interpretation of origin, thicknesses, regional distribution patterns and lithostratigraphic equivalents from neighbouring areas are also characterized.

    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
