The Characterization of a Tar Sand Sample Using Differential Scanning Calorimeters

In this study, non-isothermal kinetics and a thermal analysis tar sand sample is studied by differential scanning calorimeter and pressurized differential scanning calorimeter. Differential scanning calorimeter and pressurized differential scanning calorimeter curves revealed two reaction regions in the temperature range of 20-600 degrees C. Effect of pressure was also studied in order to see the thermal behavior of a tar sand sample under different elevated pressures. Two different kinetic methods (ASTM and Borchald and Daniels) were used to determine the kinetic parameters of the samples

Organic facies of eocene sediments in the northern gumushacikoy region, turkey

Eocene organic-rich sediments are widespread in the Amasya region of north-central Turkey and have been studied in outcrop. Detailed data from thick Eocene sediments (Derealan Formation) made it possible to construct an organic-facies framework using different zonations. Organic matter is composed predominantly of autochthonous algal and amorphous material, with a minor contribution of allochthonous terrestrial material. Kerogen in the deposits is primarily Type I, as indicated by organic petrographic observations and Rock-Eval data. Total organic-carbon content (TOC) of this deposit decreases from over 54% in limestone and shale to less than 2% in the other deposits of the Derealan Formation. Tmax values vary between 441 ° and 456° C, confirming the increase in maturation trends indicated by vitrinite reflectance data. Both organic petrographic and geochemical maturation parameters place the Eocene sediments of the Northern Gumushacikoy (Amasya) region within the B organic facies. According to the organic-carbon/sedimentation-rate relationship, the preservation of matter took place under anoxic conditions. © 1996 Taylor & Francis Group, LLC

Paleotemperature analysis of Aliaga (Izmir, Turkey) geothermal field

Mineralogical and organopetrographic analysis were carried out on core samples of four geothermal wells from the Aliaga geothermal field located in western Turkey. Whole rock mineralogy and clay minerals were determined, and thermal maturity of the different levels of the formation was defined by means of vitrinite reflectance measurements. The measured maturity gradients compiled from analytical data for four wells and outcrops ranged from low to very high values
