Opis:: Evaluation possibility of a low-quality Jordanian oil shale from Sultani, central Jordan as an alternative clean fuel by flotation technique was investigated. Oil shale sample was characterized with mineralogical and chemical analysis. X-ray fluorescence spectrometer, X-ray diffraction and Fourier transform infrared spectroscopy showed that calcite is the dominant mineral followed by quartz mineral. Other minerals such as apatite and gypsum were detected. Thermogravimetric analysis revealed that mass loss is due to organic matter decomposition at 280–600°C and carbonate decomposition at 650–850°C Fourier transform infrared analysis showed the main organic groups. The effects of collector and frother doses, pulp concentration and pulp pH on the flotation performance were investigated. The kerosene and MIBC were used as collecting and frothing agents, respectively. The optimal flotation performance occurred for a collector dosage of 1000g/t, a frother dosage of 600g/t, a pulp concentration of 20g/L, a pulp pH of 4.

Opis:: Egyptian oil shale from Red Sea area is upgraded via oil agglomeration technique to achieve a clean fuel. A representative sample is characterized to identify its undesirable components and its liberation size. The quartz, apatite, calcite, siderite and anhydrite are the main gangue minerals. The sample was pulverized to less than 20 µm for efficient liberation. The impact of anionic (Calcium dodecyl benzene sulfonate, CDBS) or/and cationic (Cetrimonium bromide, CTAB) surfactants on the zeta-potential and agglomeration process was investigated in presence of different kerosene concentrations. A concentrate of 62% kerogen with 95% recovery was obtained from feed of 29% kerogen using 0.1% CTAB/CDBS mixture in 2% kerosene emulsion.

Opis:: In the present study, the effect of cementing properties of oil shale ash on the compressive strength of the concrete mixtures produced from oil shale ash, cement, sand, and water was investigated. The used shale ash was produced by direct combustion at 830oC in a laboratory muffle furnace of the El-Lajjun oil shale. Based on the chemical composition of shale ash (OSA), it was concluded that this material consists of a high percentage of CaO which forms the properties of cement materials as well as the contents of SiO2, Al2O3, and Fe2O3 form the properties of pozzolanic materials. Oil shale ash (OSA) materials have diverse applications as alternative materials for the construction industry and construction technology to reduce environmental risks and achieve sustainability. The results showed that the pressed specimen with 40 wt. % OSA content, 50 wt. % sand content and 30% MW obtained the highest compressive strength of about 9.1 MPa after 28 days of hardening. The highest value of 28 days compressive strength for a compacted specimen containing 35 wt. % OSA and 35% MW were achieved with 12 MPa at a compaction pressure of between 25 and 30 MPa. High compressive strength values were found to be achieved in the compressed specimens by controlling mixing water. It is also indicated that the compressive strength increases as OSA content in the compressed specimen increases and increases as compaction pressure increases.

Opis:: In Poland, the focus so far has been on unconventional gas deposits, but equally interesting are unconventional oil deposits. As a result of intensive research in the past few years, it was found that we have significant deposits of oil shale, which may be rich in both gas and oil. Undoubtedly, after a period of research and analysis on the prospects of the presence of shale gas in these structural units would come the turn of the shale oil. In the article on the basis of industrial materials have been characterized: — shale formations in the basin of the Baltic - Podlasie - Lublin (potential of the Silurian and Ordovician), — Prągowiec ravine (southeast of Kielce) - Graptolitic Shales (Silurian) — menilite shales in the Carpathians external-especially of south of Rzeszów in municipalities Błażowa, Boguchwała, Wojaszówka. — discovered heavy oil deposit Lubaczów

Opis:: The results of X-ray diffraction, thermogravimetric and FTIR spectroscopy analyses of mineral composition indicated that the El-Lajjun oil shale is principally composed of calcite, quartz with minor amounts of kaolinite), gypsum, and apatite. The obtained oil shale ash products at 830 °C and 1030 °C are dominated by lime, quartz, anhydrite, portlandite, gehlenite, and amorphous phases. The TGA weight loss curves clearly indicate that it occurred in the temperature range from 310 to 650 °C. The decomposition of oil shale carbonates was detected above 750°C. The functional groups in the organic material of oil shale are dominated by the aliphatic hydrocarbons, the semi-ash of which had diverse structures of polycyclic aromatic hydrocarbons. The most intensive of combustion occurred in the temperature range of 400–750 °C. In this temperature range, about 75 wt.% was accounted for the total mass loss.

Opis:: In the current century, natural gas has become the most important fossil energy resource and also important en-ergy fuel in general. And these are both due to significant resources, especially of unconventional natural gas, and ease of transport or transmission, use but also the level of carbon dioxide emissions from burning natural gas. Significant increase in gas consumption, in all regions, will be marked in the energy sector. Northern America and Western and Central Europe consume most of the gas on electricity and heat production. The exploration of unconventional gas reservoirs has been discussed recently in several scientific fields. Technical, organizational and economic challenges related to sustainable exploration, documentation of reserves, exploitation and devel-opment of shale gas technology have been addressed in this paper. Activities oriented to acceleration of pro-specting and investment activities as well as difficulties with introducing pro-ecological procedures and technical modifications caused by minimization of influence of the drilling and environmental simulation of production wells have been presented. This study explains some ecological aspects of the extraction technology. The pace of technological development in Poland may be considerably delayed by the new requirements set by geological and mining law, slowing down of exploration works and recognition of most important gaseous hori-zons. The scope of investments spent on infrastructure for treating, transport and distribution of gas may have an impact on the rate of realizing energy investment. The rate of development of industry will be conditioned by properly defined economic objectives and the feasible development of gaseous energy industry, being an element supporting the classic coal energy, now mainly a regulation of energy sales in peak seasons. Probable scenarios (based upon business, legal and geological situation) have been discussed.
Gaz ziemny jest obecnie jednym z najważniejszych nośników tak energii kopalnej, jak i energii w ogólności. Dzieje się tak z uwagi na powszechną dostępność zasobów, łatwość w jego transportowaniu, a także z uwagi na niski poziom emisji CO2 podczas spalania tego nośnika energii. Prognozuje się dalszy wzrost wykorzystywania gazu w sektorze energetycznym i to we wszystkich regionach świata. W Ameryce Północnej a także Europie Zachodniej i Wschodniej gaz służy do produkcji energii elektrycznej i cieplnej. Ostatnio coraz częściej na nau-kowych forach dyskutuje się zagadnienie eksploatacji zasobów gazu niekonwencjonalnego. W tym artykule przedstawiamy uwarunkowania eksploatacji gazu łupkowego w kontekście rozwoju zrównoważonego, prezentu-jąc aspekty techniczne, organizacyjne i ekonomiczne odnoszące się do stanu rozpoznania zasobów i ich eksploa-tacji. Przedstawiono podejmowane działania mające na celu zwiększenie poziomu pozyskiwania gazu łupkowe-go i problemy związane z wdrażaniem procedur proekologicznych i modyfikacji technicznych, wynikające z obowiązku minimalizowania wpływu na środowisko procesu wiercenia. Artykuł wyjaśnia także podstawowe aspekty ekologiczne związane ze szczelinowaniem. W Polsce rozwój tych technologii może ulec ograniczeniu z uwagi na nowe wymagania wynikające z prawa geologicznego i górniczego, spowalniające prace poszukiwawcze i rozpoznawanie zasobów. Niezbędne jest określenie poziomu środków finansowych niezbędnych do tworzenia infrastruktury związanej z pozyskiwaniem, transportem i dystrybucją gazu. Ujmując inaczej, szybkość rozwoju przemysłu gazowego będzie uwarunkowana przez właściwie rozpoznanie uwarunkowań ekonomicznych. W artykule przedstawiono także prawdopodobne scenariusze na przyszłość, oparte na podstawach biznesowych, prawnych i geologicznych.

Opis:: One way to cut down the consumption of diesel fuel in domestic heating in Jordan is to blend it with shale oil, which may be extracted from oil shale. This leads to a cut down in the national fuel bill in Jordan. Unfortunately, shale oil contains significant amounts of sulfur as impurities and upon burning sulfur oxides are emitted causing a negative environmental impact, and hence desulfurization of such fuel blends is essential. This may be achieved by adding activated carbon to the fluids. The process of removing sulfur from shale oil is crucial for safeguarding the environment, human well-being, and equipment, as well as meeting regulatory requirements and creating superior-quality goods. In this study, a domestic boiler was utilized to evaluate the degree of desulfurization process of blends of diesel and shale oil fuels upon their burning in a domestic boiler, to achieve this, blends of both fuels were prepared with varying amounts of shale oil (10%, 20%, 30%, and 40%) and various amounts of activated carbon were added to the prepared mixtures of diesel fuel and shale oil. The assessment of performance included examining the environmental impact, specifically by analyzing exhaust gases to measure the concentration of Sulfur Oxide (SO2). It was found that an increase in the concentration of shale oil in the mixture led to an increase in the concentration of SO2. However, adding more activated carbon to the mixture from the fuels resulted in a decrease in the SO2 concentration. The lowest SO2 concentration was observed when 1g of activated carbon was added per liter of the fuel mixture at a 20% concentration of shale oil, and 0.6g of activated carbon per liter of the fuel mixture at a 40% concentration of oil shale.

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:: Rewolucja łupkowa, opierająca się na gazie i ropie z łupków, nieoczekiwanie i jednoznacznie zaczęła zmieniać krajobraz energetyczny Stanów Zjednoczonych. Należy się spodziewać jej rozszerzenia poza terytorium Stanów Zjednoczonych, z daleko idącymi konsekwencjami nie tylko dla globalnej energetyki, ale także dla makroekonomii i polityki wielu krajów. Celem niniejszej pracy jest lepsze zrozumienie uwarunkowań, które doprowadziły do wyżej wspomnianej rewolucji, ocena metod eksploatacji oraz związanych z nimi zagrożeń dla środowiska naturalnego, przedstawienie scenariuszy, jakich można racjonalnie oczekiwać w nadchodzących dekadach, jak i próba zarysu wpływu dojrzewającej rewolucji łupkowej na polityczne i ekonomiczne decyzje dokonywane przez kraje eksportujące energię, jak również ją importujące. Prognozuje się, że najbliższe dwie dekady w Stanach Zjednoczonych dadzą początek szeroko zakrojonej ekspansji pod względem aktywności na rynku gazu i ropy z łupków. W skali globalnej, liderami przemysłu łupkowego mogą być te kraje, które są już znaczącymi producentami gazu i ropy naftowej. Ustanowienie ramowych założeń mających umożliwić i wspierać bezpieczny rozwój przemysłu łupkowego jest warunkiem koniecznym dla rozpoczęcia eksploatacji łupków. Najważniejszą konsekwencją udanej rewolucji łupkowej będzie presja na obniżkę cen gazu i węgla na rynkach regionalnych oraz ropy naftowej na rynkach globalnych.
The shale gas and oil revolution has unexpectedly and forcefully begun to change the energy landscape in the United States. It is expected to spread beyond the US, with far reaching implications for the global energy map, but also for the macro-economy and politics of many countries. The purpose of this paper is to bring a better understanding to what prompted the revolution, to assess the production methods and associated environmental concerns, to speculate what can reasonably be expected in coming decades, and to sketch the full impact of a ripening shale revolution on the emerging economic and political policy choices for energy exporting and importing countries.We find that a large scale expansion can be expected in US shale gas and oil activities in the coming two decades. Globally, the shale leaders are likely to be countries that are already significant gas and oil producers. Setting up a policy framework to allow and promote shale development in a safe manner is a necessity for the launch of shale exploitation. The most important implication of a successful shale revolution would arguably be a downward pressure on gas and coal prices in regional markets and on the global oil price.

Opis:: Thermal maturity modelling was carried out in over sixty wells along the SW margin of the East European Craton (EEC). The burial and thermal history modelling of the EEC, using thermochronological data, allowed the construction of burial history maps showing its geological development in the Phanerozoic. These results have proved that the Ordovician and Silurian source rocks occurring at the SW margin of the EEC reached a maximum palaeotemperature in the Palaeozoic, mainly during Devonian-Carboniferous time and at the latest during the Silurian in the most westerly part of this margin, along the Teisseyre-Tornquist Zone. In Mesozoic and Cainozoic time, the Ordovician and Silurian strata generally were subjected to cooling or to very minor heating, certainly below the Variscan level. The maximum burial and maximum temperature of the Ediacaran-Lower Palaeozoic strata were reached during the Early Carboniferous in the Baltic Basin and during the Late Carboniferous in the Lublin area, and even in the Early Permian in the SE corner of the Lublin Basin. Thus, the main period of maturation of organic matter and hydrocarbon generation in the Ordovician and Silurian source rocks was in the Late Palaeozoic (mainly Devonian-Carboniferous) and in the westernmost zone along the Teisseyre-Tornquist line at the end of the Silurian.
