|  Methods and Applications in Reservoir Geophysics
Edited by David H. Johnston
Geophysics is not simply an exploration tool. The tasks of delineation and characterization at the reservoir scale are applied throughout the life cycle of a field. Reservoir geophysics, once an emerging application, is now mainstream. Methods and Applications in Reservoir Geophysics (SEG Investigations in Geophysics No. 15) not only demonstrates the value of geophysics in reservoir management but also shows how to apply geophysical technologies more effectively in reservoir studies. The chapter editors have selected more than 40 papers from SEG and other journals and have added 13 new contributions. In the reservoir-engineering tutorial, geophysicists will discover a rich source of information on issues and data that are critically important to the engineer. In the geophysics tutorial, the engineer and the geophysicist will find explanations of the tools and data discussed in the book's case studies. Each chapter then focuses on a different phase of field life: exploration appraisal, development planning, and production optimization. Geophysics is used in each of those stages to help address the critical technical issues and business decisions that the reservoir-management team faces. The case studies demonstrate the processes, methods, and techniques used in reservoir geophysics, not just the results. The last chapter explores the road ahead and emerging technologies that define the future of reservoir geophysics. This book will be valuable for geophysicists, engineers, and all members of the reservoir-management team who want to ensure that the right data are used to maximize reserves, optimize recovery, and contain costs. | |  Geophysics Today: A Survey of the Field as the Journal Celebrates its 75th Anniversary
Edited by the Editors of Geophysics
This year Geophysics is 75 years old. In celebration, your editorial team has invited a collection of papers written by well-recognized experts in various areas of exploration geophysics. These invited papers not only form part of the present book, but they also appear in the September-October special section of our journal. Geophysics Today: A Survey of the Field as the Journal Celebrates its 75th Anniversary complements this special section with an additional group of papers, drawn from Geophysics during the recent past, that address areas the invited articles did not. The result is a snapshot of the state of the art in our field as Geophysics passes its three-quarters century mark. This book is Geophysical References Series No. 16.

|  Heavy Oils: Reservoir Characterization and Production Monitoring
Edited by Satinder Chopra, Laurence R. Lines, Douglas R. Schmitt, and Michael L. Batzle
Heavy Oils: Reservoir Characterization and Production Monitoring, edited by Chopra, Lines, Schmitt, and Batzle, presents an integrated and general description of the development and production of heavy oil fields throughout the world, with particular emphasis on geophysical characterization of heavy oil fields. The book (SEG Geophysical Developments Series No. 13) introduces the important economic impact of heavy oil as a major world energy resource, with reserves being roughly equivalent to the world's conventional oil reserves. The origin of heavy oil sands, its phase behavior, and unique physical properties are described in the context of the world's major heavy oil fields. Particular attention is paid to the unique rock physics of heavy oil sands, which offers challenges to the conventional theories that describe fluid-saturated sandstones. Given the high viscosity and density of this oil, there are distinct challenges to production. This book edited by Chopra et al. describes a wide range of enhanced oil recovery methods (EOR) including steam injection, solvent injection, cold production, and combustion. In all these EOR methods, it is imperative to accurately describe the reservoir before and after production. As pointed out by the book, this reservoir characterization requires integration of engineering, geology, and geophysics, with rock physics supplying a key link. The book emphasizes geophysical methods, especially time-lapse 3D seismic methods, while providing numerous case histories from the 2007 SEG Development and Production Workshop at the University of Alberta. The heavy oil geology and production from major heavy oil reservoirs is compared and contrasted. Given the economic importance and need for detailed information about heavy oil production, this book should prove interesting to all reservoir engineers, geologists, and geophysicists in this field.
| |  Geophysical Characterization of Gas Hydrates
Edited by Michael Riedel, Eleanor C. Willoughby, and Satinder Chopra
The occurrence of gas hydrates in large quantities worldwide and their immense energy potential have prompted concerted efforts into their exploration and understanding over the last many years. During this time, geophysical characterization of natural gas hydrate occurrences by seismic and other methods have gained prominence, and such studies have been reported from time to time. However, no compilation of such studies was ever attempted. This SEG publication, Geophysical Characterization of Gas Hydrates (Geophysical Developments No. 14), is the first book on the topic that focuses on documenting various types of geophysical studies that are carried out for the detection and mapping of gas hydrates. The editors have organized 20 papers as individual chapters into five sections, along with a brief introductory chapter for each section. Section 1 has two chapters that serve as introduction and motivation for geophysical investigations into gas hydrates. Section 2 on seismic imaging includes five chapters that discuss several seismic techniques with applications to various geologic settings. These comprise the indicators of gas hydrates in marine data such as BSRs, the use of AVO, seismic inversion, full-waveform inversion, VSPs, and multicomponent data in the assessment, detection, and quantification of gas hydrates. As the occurrence of gas-hydrate deposits affect the physical and chemical properties of the host sediments, various additional geophysical techniques including electromagnetics, magnetics, and infrared imaging are used for their detection, and these comprise Section 3. Section 4 discusses borehole methods aimed at characterization of gas hydrate environments and includes the conventional log-based measurements, special logging measurements like NMR, as well as logging-while-drilling, and measurement-while-drilling applications. Because of their higher vertical resolution, such measurements serve as useful calibration points that are required for accurate analysis. Finally, Section 5 discusses rock-physics modeling and gas-hydrate laboratory studies. While rock-physics modeling helps link log measurements with seismic reflection profiles for estimating gas-hydrate concentrations, creation of artificial gas-hydrate-bearing sediments using different techniques is also necessary, for instance, when characterizing engineering properties of gas-hydrate-bearing sediments. The contributing authors for the different chapters are experts and well-known researchers in their respective fields. The book will be of interest to geophysicists, petroleum geologists, geochemists and those enthusiastic minds who seek the unknown in the field of energy resources. | | | Order these titles online or by e-mail. | Didn't find what you were looking for?
