Opis:
The Ecca Group, a subdivision of the Karoo Supergroup (Upper Carboniferous - Lower Jurassic) in SW Botswana is a sequence deposited as marine deltaic bodies considered to have been supplied from a cratonic source elevated north of the basin. The Karoo strata in this region are covered unconformably by sands of the Kalahari Beds (Upper Cretaceous - Recent). Therefore the bedrock outcrops are extremely rare, limited in size and a low number of boreholes drilled in this vast area (ca. 340 x 540 km) provide the only insights into the succession of the Karoo Supergroup. Very long distances between individual boreholes make correlation, interpolation between localities and interpretations of geometry of lithological bodies that would provide clues supporting basin analysis by traditional means problematic. To achieve the first approximation of the space-time relations between lithologically complex Ecca Group lithofacies associations modelling of these sediments using Petrel software was performed. These relations in turn suggest evolutionary trends of the basin during deposition of the Ecca Group strata. The model suggests two main zones of supply indicated by two distinctly different patterns of deltaic lithofacies associations, and their evolution controlled by post-Dwyka palaeotopography and its subsequent modifications by local subsidence in the centre of the depository. Initially rapid southward progradation of relatively fine-grained delta body located in the west of the area was followed by subsidence-induced aggradation interrupted by stages of abandonment and marine transgression. Such variations, emphasised by the presence of sandy clinoforms of the delta lobes separated by basinal "fines", imply significant interplay between rates of supply and subsidence. On the other hand, the delta formed in the east contains relatively high proportion of coarse-grained sandstone facies overlying prodelta fines as laterally extensive tabular body formed most probably by lateral migration of distributary channels and delta-front mouthbars, and devoid of abandonment stages. Proximal litofacies of the "western delta" fill the subsiding depocentre and grade distally into synchronously deposited prodelta fines towards the south. By contrast, distal fine-grained prodelta facies fill basin depocentre in the eastern area and are overlain by proximal facies of the "eastern delta".

Opis:
The present age of digital subsurface mapping is represented above all by quantitative maps based on regular grids. They are created on the basis of various input data: digitized contours, widely comprehended well data, 2D and 3D seismic, and qualitative geological maps. Scope and the data utilization and the applied methodology of processing are strictly dependent on the scale and purpose of a given map; for regional and detailed maps they are significantly different. However, irrespective of the map scale, correct models, reflecting probable subsurface variability, instead of the input data spatial distribution and applied estimation algorithm themselves, are conditioned by chances of integrating of all the mentioned types of data. These purposes can be achieved only through the application of the most flexible interpretive programs such as ZMAP–Plus or mapping modules of the Geographix system. High quality quantitative subsurface maps based on regular grids are nowadays used first of all in petroleum exploration and geothermal research. But development of such studies may contribute to creation of high-quality, interactive, subsurface models, available not only for owners of expensive professional software but also for all geoscientists interested in these topics.

Opis:
The paper considers the potential for new discoveries of gas accumulations in the Rotliegend Basin on the basis of the analysis of reservoir and hydrochemical tests and the results of reservoir simulations. Several reservoir simulations carried out in the study area (history of production and history matching) demonstrate the regional migration of reservoir waters. The integration of the simulations with mathematical calculations (in consistency with Hubbert’s theory) and with hydrochemical results permits recognition of the regional hydrody- namics and the potential localization of gas fields. In an analysis of the current hydrodynamic and hydrochemical conditions of reservoir waters in the Rotliegend (Lower Permian) strata, attention was focused on part of the sedi- mentary Rotliegend Basin, located south of the Wolsztyn-Pogorzela High, utilizing materials available from drilling and noting the differences between this area and the northern sub-basin. The current hydrogeological conditions and the dynamics of fluid transfer in the Rotliegend Basin are an effect of structural rearrangement during the Laramide orogeny. The basin hypsometry, resulting from the Laramide movements, became the decisive factor that controlled the filtration of groundwater. The recent hydrodynamic characteristics of migrating reservoir waters are reflected in the P-T (fluid pressure and temperature gradient) distribution pattern. Hence, the analysis of this distribution may reveal reactions that have taken place over time. It must be emphasized that clusters of gas fields are located in the zones occupied by stagnant groundwater (rNa/rCl<0.75) under hydrostatic (or slightly higher) pressure.

Opis:
The Flow Zone Index, FZI, applied to order relations between the effective porosity and permeability of the Rotliegend sandstones in the Polish part of the Southern Permian Basin turns out to be a useful and effective factor to evaluate ability of media flow in a rock formation. A dataset of over 2000 samples from 78 wells was analysed. Based only on porosity and permeability, FZI includes all non-parameterized features of rocks as tortuosity and diameters of porous channels, volume of trapped parts of capillary roads, specific surface of pore space, and others. When FZI increases, the ability of fluid to move through the porous space increases. In most cases, the Rotliegend sandstones reveal FZI in the range of 0.5-2.0. The highest FZI, ca. 100, is related to fractured part of the studied formation. The combination of FZI and facies information from several wells in the study area (over 1200 samples) showed a good correlation. On the basis of FZI we can divide a set of samples of the Rotliegend sandstone into groups of defined fluid flow abilities and relate them to facies. Also, we show the way of estimation of the reliable values of permeability in full geological log of a borehole on the basis of FZI, and the total porosity determined from well logging interpretation.

Opis:
In the years 2010-2013, analysis of rocks that build the sedimentary covers in Poland was carried out from the point of view of energy utilization accumulated in hot dry rocks – used in Enhanced Geothermal Systems (EGS). As a result of a number of analytical studies, the area situated in the central part of Poland was selected as one of prospective areas for location of EGS in sedimentary rocks. This area encompasses a major part of the Mogilno-Łódź Trough, a part of the Kujawy Swell and a small fragment of the Fore-Sudetic Monocline. The most favourable conditions for development of EGS occur in deposits of the Lower Triassic in the Krośniewice-Kutno vicinity where they are buried to depths greater than 5000 m b.s.l., have thicknesses exceeding 1500 m and are characterized by porosity about 2.5% and permeability about 0.1 mD. In the selected area, thermal characterization of the formation was carried out for location of the EGS in sedimentary rocks. The temperature at the top of Lower Triassic reservoir is in the range 165-175°C. Characterization of petrophysical parameters constituted the basis for further modelling of EGS utilization in selected area.

Opis:
Numerical modelling of the Carboniferous–Permian petroleum system in the Polish Basin was carried out using PetroMod software. The Carboniferous source rocks contain organic matter mostly of a humic nature (gas-prone Type III kerogen). Subordinately, only in the Lower Carboniferous deposits, kerogen of algal marine origin and mixed Type II/III kerogen occur. The quantity of dispersed organic matter is variable, but usually below 2% TOC. In the Carboniferous section, a progressive increase in the maturity of organic matter with depth was observed, from approximately 0.5% Rr at the top of the Westphalian in marginal parts of the Carboniferous basin to over 5.0% Rr at the bottom of the Lower Carboniferous in the eastern Fore-Sudetic Homocline. The thermo- genic generation of hydrocarbons continued from the late Westphalian (eastern Fore-Sudetic Homocline and partly Pomerania) throughout the Mesozoic, up to the Late Cretaceous. The advancement of this process is va- riable in different parts of the Carboniferous basin, reaching up to 100% of kerogen transformation in the zones of maximum maturity of organic matter. However, the most intensive periods of gas generation and migration were the Late Triassic and the Late Jurassic. The most prospective areas are located NE of Poznań–Kalisz line and SW of Poznań.
