Opis:
Leaching studies were performed to develop a suitable method for extraction of uranium from domestic uranium ores: dictyonemic shales and sandstones. The extracting procedure was composed of successive separation steps: crushing and grinding, acid or alkaline leaching, solid-liquid separation, and inductively coupled plasma mass spectrometry (ICP-MS) analyses of post-leaching solutions. The influence of such process parameters as temperature, pressure, particle size of solid material, kind of leaching solution and its concentration, on the recovery efficiency of uranium and accompanying metals were tested. The efficiency of uranium leaching with sulphuric acid solution achieved 81%. Satisfactory results were obtained for the alkaline leaching process. It was found that uranium can be selectively extracted by the alkaline leaching solution. Almost complete extraction of uranium from sandstones was achieved when a mixture of sodium carbonate and sodium hydroxide, with hydrogen peroxide as a leaching solution was used.

Opis:
The possibility of examining rock pore structure by the means of computed X-ray microtomography was presented. Parameters characterizing the pore structure, such as: porosity and coefficient of homogeneity of pore structure by local porosity examination, box counting dimension, mean chord length, normalized Euler number, as well as coordination number were all determined through pore structure image analyses. Complementary methods, such as helium pycnometry, mercury injection capillary pressure and NMR were used to determine the porosity along with other factors to make the comparison and determine mutual relationships between petrophysical properties obtained from various sources. The study covered the Rotliegend sandstones of eolian origin. Laboratory investigation of the reservoir properties was focused on three areas, according to their geological regions, where the Rotliegend sediments showed changeability in geological features and reservoir properties. Computed X-ray microtomography showed differentiation between the investigated areas, with respect to their pore structure and porosity development. This differentiation was confirmed by means of other applied laboratory methods.

Opis:
This work examines the possibility of implementing the statistical method, Compositional Data Analysis (CDA), to rock porosity measurement data. The rock samples analysed are different types of sandstones from Poland. Porosimetricmeasurements were carried out using the mercury injection capillary pressure method, together with computer image analysis. In this paper, compositions of data concerning pore distributions are analysed. Rock pores were distributed in 4 classes of pore dimensions: transitive pores, submacropores, realmacropores and over-capillary pores. Based on the CDAmethods it was revealed that: there is no constant proportion between transitive andmacropores in the sandstones analyzed; the variability of the realmacropores, over-capillary and transitive pores and the skeletal grains fraction is mainly one-dimensional. The relative variation between transitive pores and real macropores determines the variability in the sandstone stratigraphical groups; however, these groups are not very distinct as regards the pore sizes and skeletal grains proportion. The rock parameters: median pore diameter; threshold pore diameter and total pore area might be used as independent variables in equations that explain reasonable parts of variability of pore sizes and skeletal grains fraction log-ratios.

Opis:
The Lower Jurassic Ciechocinek Formation from the Czestochowa-Wielun region of SW Poland comprises greenish-grey muds and silts as well as poorly consolidated mudstones and siltstones with lenticular intercalations of fine-grained sands, sandstones and siderites. Analysis of a mineral composition indicates that the detrital material was derived mainly from the weathering of metamorphic and sedimentary rocks of the eastern Sudetes with their foreland and of the Upper Silesia area, and that this material underwent repeated redeposition. The Fe-rich chlorites which give the green colour to the mudstones of the Ciechocinek Formation are most probably early diagenetic minerals, genetically linked with the deposition in a brackish sedimentary basin.

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:
Rock pore space is a rock mass composed of a large number of irregularly arranged and shaped pores. The diameter of the pores and their distribution and tortuosity determine the possibility of collecting and conducting reservoir fluids (Oil, Natural Gas and Saline water). Characterization of the pore space is intended to determine the distribution and size of the cavities in the rock. The characteristics of the study is based on parameters such as porosity and permeability and upon which the petrophysical static model is built. The article discusses methods of mercury porosimetry from the aspect of the exploration of the pore space of reservoir rocks for hydrocarbons. The research results of the petrophysical parameters of samples similar to typical reservoir rocks and unconventional rocks were presented. The results of capillary pressure tests in graphic form for six samples of the Inoceramian sandstone of the Skole unit were also given. The results of the petrophysical studies show the limitations of the use of the mercury porosimetry method in investigations of low reservoir parameters. Therefore, the authors have identified the next stage of research as exploring the application of the helium porosimetry method due to the chemical neutrality of helium and its small particle size.

Opis:
The article presents knowledge based on investigation of sandstones or siltstones composition from the Paleogene flysch terrains in North-East Slovakia. Samples of frequently crumbling clastic rocks were commonly considered to be close to sandstones, composed by predominant quartz. The set of such samples, belonging to Dukla Unit Sandstones were analyzed using the XRD analyses. Beside of quartz the diffraction patterns gave the evidence in significant carbonate share with some minor to minute feldspars, mica and chlorite contents. Among majority of analyzed samples we distinguish three groups of sandstones: (1) with the abundant calcite admixture, (2) the sandstones which contain meaning dolomite portion. The group (3) is representing the samples is formed the same by quartz as by both of carbonates, each of them could form important up to prevailed mineral component. Comparison of analyzed samples mineral composition shows remarkable trend of higher calcite and dolomite contents in younger clastic sediments.

Opis:
Natural gas in the Polish Rotliegend Basin occurs in porous and permeable aeolian sandstones, and traps are mostly structural. Lithological traps are rare and occur on the northern slope of the Wolsztyn Ridge where fluvial and aeolian sandstones overlap with alluvial facies. Both fluvial and aeolian sandstones are reservoir rocks in this area. The X-ray micro computed tomography (MCT) results and microscopic observations indicate that the sandstones in lithologic traps on the northern slope of the Wolsztyn Ridge form highly compartmentalized vertical reservoir rocks composed of four types of sandstones. The profiles are dominated by very low-porosity fluvial sandstones (F2), and low-porosity aeolian and fluvial sandstones (A2, F1). The A1 type of sandstones with high porosity (10%) occurs only in some sections of the profiles. The most important diagenetic processes that reduced porosity were compaction and cementation by carbonate cements. All studied sandstones were subjected to the same diagenetic processes. However, each of the processes ran with varying intensity in different types of sandstones. Detailed analyses of pore distribution by MCT methods with respect to primary depositional or lithofacies effects, and secondary diagenetic effects, help to understand the 3D geometry of pores and pore shape-size distributions. The results can be used in the studies of other sandstones with a different origin and age.

Opis:
Przedmiotem badań były sylurskie piaskowce Acacus o zróżnicowanych własnościach petrofizycznych, wynikających ze zmiennych warunków sedymentacji. Zmienne zailenie oraz wysoko zmineralizowana woda złożowa spowodowały zaniżenie oporności piaskowców. Dodatkowo, obecność minerałów bogatych w żelazo spowodowała, że standardowa interpretacja profilowań geofizyki otworowej w celu wyznaczenia porowatości była nieefektywna. Wykonano podział piaskowców na 5 typów litologiczno-strukturalnych, oparty na cechach rozpoznanych w wyniku badań laboratoryjnych na próbkach piaskowców. Porowatość i przepuszczalność dla wydzielonych typów piaskowców okazały się znacznie lepiej skorelowane w porównaniu do całej grupy danych. Podział zastosowano podczas interpretacji profilowań geofizyki otworowej.

Carpathian Foredeep
Opis:
The Upper Badenian and Sarmatian sandstones recognized from boreholes in southeastern Poland and western Ukraine are very fine to medium-grained subarkosic and sublithic arenites and wackes. The deposits underwent diagenesis well below 100°C, and their evolutionary pathways of diagenetic and related reservoir properties represent eo- and mesodiagenesis. Eodiagenesis here comprised mechanical compaction, development of chlorite, microcrystalline calcite, pyrite, siderite, kaolinite and quartz, and dissolution of feldspar and mica grains. Mesodiagenesis included quartz and K-feldspar overgrowths, albitisation, crystallisation of dolomite and ankerite and coarsely crystalline calcite, dissolution of feldspar grains and carbonate cement, and illite growth. The isotopic data of δ18OVPDB of carbonate cements suggest their crystallisation from porewater which is a mixture of marine and meteoric waters. The δ13CVPDB values suggest derivation of carbon from microbial methanogenesis of organic matter. The 87Sr/86Sr values in coarsely crystalline calcite are higher than those of Badenian seawater. The radiogenic strontium may have been supplied during diagenesis by meteoric waters draining the continental area. The Middle Miocene sandstones show better filtration abilities (good and very good) in the western part of the study area (Poland) than in the east. Primary intergranular porosity is more frequent than secondary intragranular and intercrystalline porosities.The primary porosity was diminished due to compaction and cementation from west to east. Some increase in porosity was caused by dissolution of detrital grains and by decay of soft parts of organisms.

Opis:
The paper presents the results of analysis of surface roughness parameters in the Krosno Sandstones of Mucharz, southern Poland. It was aimed at determining whether these parameters are influenced by structural features (mainly the laminar distribution of mineral components and directional distribution of non-isometric grains) and fracture processes. The tests applied in the analysis enabled us to determine and describe the primary statistical parameters used in the quantitative description of surface roughness, as well as specify the usefulness of contact profilometry as a method of visualizing spatial differentiation of fracture processes in rocks. These aims were achieved by selecting a model material (Krosno Sandstones from the Górka–Mucharz Quarry) and an appropriate research methodology. The schedule of laboratory analyses included: identification analyses connected with non-destructive ultrasonic tests, aimed at the preliminary determination of rock anisotropy, strength point load tests (cleaved surfaces were obtained due to destruction of rock samples), microscopic analysis (observation of thin sections in order to determine the mechanism of inducing fracture processes) and a test method of measuring surface roughness (two- and three-dimensional diagrams, topographic and contour maps, and statistical parameters of surface roughness). The highest values of roughness indicators were achieved for surfaces formed under the influence of intragranular fracture processes (cracks propagating directly through grains). This is related to the structural features of the Krosno Sandstones (distribution of lamination and bedding).

Opis:
Upper Miocene sandstones in the Sava Depression (Northern Croatia) are potential targets for carbon dioxide (CO2)-based enhanced oil recovery (EOR) processes or mineral carbonation with reservoir brine. In general, sandstone lithology, even rich with aluminosilicate minerals, is not the most favourable rock medium for efficient sequestration of CO2 in minerals. However, CO2 is naturally sequestered in minerals when CO2 is injected into sandstone reservoirs and subdued to carbonation. The timescale of such sequestration is on the order of 104–105 years. Upper Miocene sandstones in the Sava Depression could incorporate up to 25% of aluminosilicate minerals (10% K-feldspars) and up to 20% dolomites and often laterally transition between pelitic and psammitic lithofacies, rich in clay minerals (15% micas). Total volumes are approximately 107 and 62 million m3 (approximately 268 and 155 million t of rocks), respectively for the potential injection reservoirs in the Ivanić Field. Oil saturation in the injection intervals is estimated to be approximately 14.8 and 4.1 million m3 respectively. Geochemical analogies and mineralogy can be used to support predictions for the low percentages of injected CO2 that may be stored during carbonation and form secondary minerals

Opis:
The source of the clastic sediments in the Croatian part of the Pannonian Basin System (CPBS) during the Late Pannonian and Early Pontian was the Eastern Alps. Clastic sediments were redeposited several times before they reached the Sava Depression. The depositional environment and sediment transport mechanisms have been subject to detailed analysis described in many publications, and this study builds on previous research. We have carried out geostatistical mapping of selected Upper Pannonian and Lower Pontian reservoir variables of the Kloštar Field, located to the west of the Moslavačka gora Mt. (Croatia). This has shown that the Moslavačka gora Mt. was a secondary, local source of sediment, in contrast to the previous interpretation of a single, distant clastic source (Eastern Alps) for the CPBS during the Late Miocene. As the mineralogical composition of the Moslavačka gora Mt. and the Eastern Alps is very similar, the dominant direction of turbidity currents obtained by sequential indicator simulations are used to suggest that a modest amount of detritus was eroded from the Moslavačka gora Mt. and mixed with detritus sourced from the Eastern Alps.
