Matrix Retention of Hydrocarbons
During the Rock-Eval pyrolysis S2 stage, the heavier hydrocarbon molecules generated during to the thermal maturation of kerogen, are often retained by the shale-matrix. Argillaceous matrices of organic-rich s...

Chapter
Summary
Geochemical profiling-data of unconventional shale reservoirs is a key step in their characterization. However, it can provide misleading and ambiguous interpretation due to a lack of thorough understanding of...

Chapter
Introduction
Organic-rich shales, until recently evaluated mainly as source-rocks feeding conventional oil and gas reservoirs, are now considered more broadly as both potential source rocks and as potential unconventional ...

Chapter
Source-Rock Geochemistry: Organic Content, Type, and Maturity
Petroleum generation and storage in unconventional shale reservoirs is primarily controlled by the organic-matter present within shales. While organic richness is very important for acting as unconventional pe...

Chapter
Sedimentary Biomarkers and Their Stable Isotope Proxies in Evaluation of Shale Source and Reservoir Rocks
Organic-matter present in shales is the source of gaseous hydrocarbons and its quantity and quality determines the gas generative capacity of the rock. It is represented by the total organic carbon (TOC) conte...

Chapter
Source-Rock Evaluation Using the Rock-Eval Technique
The basic pyrolysis techniques used for source-rock geochemical analysis are generally simple and can be interpreted in a straightforward way. However, some of the data generated can be misleading and lead to ...

Chapter
Kerogen’s Potential to Be Converted into Petroleum: Reaction Kinetics and Modelling Thermal Maturity Plus Petroleum Transformation Processes
This chapter considers the data measurement, analysis, modelling and interpretation techniques associated with kerogen’s conversion into petroleum fluids, thermal maturity and petroleum generation in organic-r...

Chapter
Organic and Inorganic Porosity, and Controls of Hydrocarbon Storage in Shales
Porosity is a primary characterization parameter for organic-rich shales, as gas/oil exists within the pore spaces within these formations. Careful analysis and quantification of the various attributes of the ...

Chapter
Conclusions
Coal and biomass will continue to remain as the major source for energy mainly due to their abundance, availability, and affordability. More and more ash will be generated in the coming years. Most of these as...

Chapter
Genesis and Characteristics of Coal and Biomass Ash
The coal ash and biomass ash produced from their respective combustion are widely variable in terms of their physical and chemical properties. Thorough understanding of their properties is a prerequisite for t...

Chapter
Environmental Effects of Coal and Biomass Ash Generation
There are apprehensions of presence of potentially toxic organic and inorganic substances in coal and biomass ash. Potentially toxic elements, PAHs, PCBs, and radioactive elements are some of the environmental...

Chapter
Introduction
Coal, a naturally occurring laminated organic-sedimentary rock, has been a source of energy for several decades. Being composed of essentially lithified-plant materials, which were initially deposited in swamp...

Chapter
Utilization of Coal and Biomass Ash
Sustainable utilization of the ash generated from the combustion of coal or biomass is a big challenge for the power industry. Huge quantities of ash are generated and, in general, they are disposed-off in ash...

Thermal Behavior of Some Indian Coals: Inferences from Simultaneous Thermogravimetry–Calorimetry and Rock–Eval
In this work, thermal behaviors of ten coal samples (across different thermal maturity levels) collected from five different open cast mines in the Jharia and Raniganj basins, India, were examined using differ...
