Product Description

Petroleum Geochemistry and Exploration in the Afro-Asian Region includes 29 papers presented at the 6th International Conference on Petroleum Geochemistry and Exploration in the Afro-Asian Region.

Petroleum geochemistry has played a crucial role in determining effective source rocks, classifying petroleum systems and delineating the geneses of conventional and unconventional oils and gases. By reference to petroleum geochemistry, the dynamic process of petroleum accumulations can be traced, which helps determining the prospecting target areas and reducing the exploration risk. Petroleum exploration is also enhanced by basin modeling and petroleum system classification, through the application of geochemical data.  There has been significant progress in petroleum exploration due to the application of molecular geochemistry and biomarkers. Advances in this area include the identification and application of age-indicating biomarkers, the application of diamondoids in appraising the cracking level of crude oils, and the application of the compound-specific isotope analysis of biomarkers and the compound-specific isotope analysis of diamondoids (CSIAB and CSIAD) in oil-source correlation and quantitative identification of source-commingled oils. In reconstructing the history of oil and gas accumulations, three other techniques are of note: the dynamics of hydrocarbon generation, the dynamics of carbon isotopic fractionation and the analysis of liquid historical recordings (inclusions).

Petroleum Geochemistry and Exploration in the Afro-Asian Region is an invaluable source of information for oil and gas explorers, petroleum geochemists and students of petroleum geochemistry.  Researchers in petroleum companies and institutes will also find this publication useful.

Product Description
This volume is for environmental researchers and government policy makers who are required to monitor environmental quality for their environmental investigators and remediation plans. Ituses concepts and applications to aid in the exchange of scientific information across all the environmental science disciplines ranging from geochemistry to hydrogeology and ecology to biotechnology.Focusing on issues such as metals, organics and nutrient contamination of water and soils, and interactions between soil-water-plants-chemicals, the book synthesizes the latest findings in this rapidly-developing, multi-disciplinary field. Cutting-edge environmental analytical methods are also presented, making this a must-have for professionals tasked with monitoring environmental quality. These concepts and applications help in decision making and problem solving in a single resource.

*Integrative approach promotes the exchange of scientific information among difference disciplines
*New concepts and case studies make the text unique among existing resources
*Tremendous practical value in the fields of environmental quality and remediation with an emphasis on human health and ecological risk assessment ... Read more

Product Description
This textbook and reference outlines the fundamental principles of thermodynamics, emphasizing applications in geochemistry.The work is distinguished by its comprehensive, balanced coverage and its rigorous presentation.The authors bring years of teaching experience to the work, and have attempted to particularly address those areas where other texts on the subject have provided inadequate coverage.A thorough review of the necessary mathematics is presented early on, both as a refresher for those with a background in university calculus, and for the benefit of those coming to the subject for the first time.The text is written for students in advanced undergraduate or graduate-level geochemistry as well as for all researchers in this field. ...

Product Description

This book combines earth science, subsurface hydrology and environmental geochemistry, providing a comprehensive background for specialists interested in the protection and sustainable management of the subsurface environment. The reader is introduced to the chemistry of contaminants, which usually disturb the natural equilibrium in the subsurface as a result of human activity. The major focus of the book is on contaminant reactions in soil solutions, groundwater and porous media solid phases, accounting for their persistence and transformation in the subsurface, as they are transported from the land surface into groundwater. Discussions on selected case studies are provided.

The petroleum geochemistry deskbook
The book is one of the best examples of comprehensive and logic presenatation of such a complex multidisciplinar area as petroleum geochemistry is. The author has embodied the main concepts conserningpetroleum geochemistry as a field of knowledge, its fundamentals, andpractical application as well as applications to other areas into shorttopics avoiding complexchemical classifications and providing caseillustrations.The glossary is illustrated in clear and comprehensivemanner wich permitsthe user to acess rapidly the necessary informationboth to the specialist and professionals from other areas evenunfamilirized with the subject. Taking into account all mentioned above, Iguess the work could be entitled also as "Basics of petroleumgeochemistry" and in my mopinion is higlhy recommended as a deskbookfor all geologists and enviromental engineers or as a short course for bothgraduate and post-graduate students. ...
