This exceptional book reveals the results of twelve years of extensive thermoanalytical investigations into petroleum and its products with the aid of tables, diagrams and references. Firstly, the methods employed in obtaining thermoanalytic data, in particular thermogravimetry, differential thermal analysis and differential. Technologies for oil shale production include surface and in-situ retorting. This study focusses on in-situ oil shale production methodologies. The process of heating oil shale to the pyrolysis temperature can be achieved by direct or indirect heating. Direct heating geometries include the Shell in-situ conversion process (ICP) using downhole.
With increase of interest in exploiting shale gas/oil reservoirs with multiple stage fractured horizontal wells, complexity of production analysis and reservoir description have also increased. Different methods and models were used throughout the years to analyze these wells, such as using analytical solutions and simulation techniques. The results demonstrated that the thermal decomposition of oil shale and its kerogen involved three degradation steps. Different thermo gravimetric data were analyzed by Friedman procedure. The values of apparent activation energy E of oil shale ranged from kJ/ mol to kJ/mol, but these of kerogen were in the range of kJ/mol to kJ/mol.
the thermal degradation and to convert into liquid or gaseous hydrocarbons. The threshold level for oil generation varies depending upon kerogen type. The determination of maturity levels is critical to the success of every oil exploration program. Recovery of immature, but organic-rich, source rocks indicate good sourceFile Size: KB. DIFFERENTIAL THERMAL STUDY OF COLORADO OIL SHALE " C. A thermal curve for a mixture of this sample with 5 per cent calcite, Fig. 4, showed a larger dip at about the same temperature which suggested that the thermal peak at ' C. for sample E was due to calcite. Similarly, curves for mixtures of sample,4 with calcite and.

Analytical method for study of thermal degradation of oil shaleAuthor: John Ward Smith. A new rapid method for shale oil and shale gas assessment.
Thermal degradation is an analytical staple of organic geochemical research but its combination with FTIR is relatively uncommon. In this study, multistep pyrolysis was performed at temperatures of °C, °C and °C.

Study on the pyrolysis of Moroccan oil shale with poly (ethylene terephthalate) Article (PDF Available) in Journal of Thermal Analysis and Calorimetry 96(3). Shale oil extraction is an industrial process for unconventional oil production.
This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities.
Shale oil extraction is usually Feedstock: Oil shale. Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced, called shale oil (not to be confused with tight oil—crude oil occurring naturally in shales).
Shale oil is a substitute for conventional crude oil; however, extracting shale oil from oil shale is more costly than the Primary: Kerogen, Quartz, Feldspar.
Oil shale is an important possible solution to the problem of energy in Jordan. To explore the technical and the economic feasibility of oil shale deposits, numerous samples are analyzed using the standard Fischer Assay (FA) method.
However, it would be useful to develop faster, cheaper, and reliable methods for determining the oil content of oil : Ziad Abu El-Rub, Joanna Kujawa, Esra’a Albarahmieh, Nafisah Al-Rifai, Fathieh Qaimari, Samer Al-Ghar.
The present study evaluates the naphthenic degradation of an acid heavy oil sample subjected to thermal degradation at °C during different times, using both classical (API degree, viscosity, TAN, total sulfur content, mercaptans, etc.) and modern analytical techniques (HTGC NMR and ESI(-)-FT-ICR MS) to understand the behavior of an acid Cited by: 5.

Major disadvantages of shale oil are that it has high aromatics, heavy metals, and sulfur contents of. Determination of the Total Sulphur Content of Oil Shale by Using Different Analytical Methods [1–5].
Estonia is highly dependent on oil shale – 90% of electricity is pro-duced from it . China has the world’s second largest resources of oil shale, which are estimated at million barrels . As the reduction of. Thermal Analysis of Co-Firing of Oil Shale and Biomass Fuels carbon, low sulfur content, and high reactivity.
Blending biomass with oil shale in co-firing applications may be a good method at addressing com-bustion issues and environmental concerns. There are many papers on thermal analysis of fossil fuels (coal, lignite.

Experimental Mettler-Toledo TGA and PerkinElmer power compensated Diamond DSC were used to study the thermal decomposition of minerals, kerogen and raw oil shale samples.
Nitrogen and carbon dioxide were used as purge gases. Purge gas flow rate in the DSC was maintained at 20 ml/min. Both theFile Size: KB. CASE STUDY OF SHALE OIL PRODUCTION hydrogenation and thermal dissolution of oil shale.
Raw shale oil extracted from oil shale can be used as fuel oil directly. However, most of the application of shale oil requires it to be re-processed there are two basic methods to extract kerogen from oil shale.
First method is a cracking process File Size: 1MB. not free-flowing, oil shale necessitates a vertically-integrated production system, meaning that extraction, processing, and initial upgrading of the liquid product occur on the mine site, with further refining taking place at refineries.
