The study of dispersed organic matter the Mesozoic sediments Gydan parametric well 130 (north Western Siberia) made it possible to reveal its genesis, maceral composition, and secondary changes. Obtained information allowed reconstructing catagenetic zoning section, determining position lower boundary oil occurrence, main zones gas generation

Organic matter (OM) type critically controls the hydrocarbon generation potential and organic pore development in black shales. However, maceral variation lacustrine shales its control on are not yet well understood. In this study, 15 Chang 7 Member shale samples of Yanchang Formation, Ordos Basin, were investigated with petrography, Rock-Eval pyrolysis, a scanning electron microscope to study ...

The purpose of this study is to characterize the relationship between organic material and thermal maturity during the process of evaluation of hydrocarbon potential. Samples studied include Miocene high volatile bituminous coal and coaly shale collected from outcrops and exploration wells in Hsinchu-Miaoli area, NW Taiwan, density centrifuge separated macerals, bituminous coal and anthracite f...

Abstract The Piedemonte Llanero Basin is located on the eastern side of Eastern Cordillera Colombian Andes. It has been subject numerous geological studies carried out for oil sector, mainly. This study presents coal-petrographical features 15 coal seams four formations from Late Cretaceous to Middle Miocene (Chipaque formation, Palmichal group, Arcillas del Limbo and San Fernando formation). A...

Over the past few years, we have been developing new NMR imaging strategies for probing the chemical and physical structure of coal. Early experiments focused on proton NMR ima ing techniques for spatially resolving individual macerals within a solid coal specimen5 Distinction of individual macerals was achieved by taking advantage of differences in proton density or in spin-lattice relaxation ...

Organic matter (OM), composed of various macerals, has a strong influence on the enrichment shale gas. Nevertheless, connection between OM-hosted pore structure and maceral type is not yet fully understood because difficulty to identify types by traditional scanning electron microscope (SEM). Using combination reflected light microscopy, focused ion beam SEM (FIB-SEM), Raman spectrum, three typ...

It is the purpose of this research to study electrostatic charging mechanisms related to electrostatic beneficiation of coal with the goal of improving models of separation and the design of electrostatic separators. Areas addressed in this technical progress report are (a) electrostatic beneficiation of Pittsburgh #8 coal powders as a function of grind size and processing atmosphere; (b) the u...
