Active Geophysical Monitoring, Second Edition, presents a key method for studying time-evolving structures and states in the tectonically active Earth's lithosphere. Based on repeated time-lapse observations and interpretation of rock-induced changes in geophysical fields periodically excited by controlled sources, active geophysical monitoring can be applied to a variety of fields in geophysics, from exploration, to seismology and disaster mitigation. This revised edition presents the results of strategic systematic development and the application of new technologies. It demonstrates the impact of active monitoring on solid Earth geophysics, also delving into key topics, such as carbon capture and storage, geodesy, and new technological tools.

This book is an essential for graduate students, researchers and practitioners across geophysics.

Outlines the general concepts of active geophysical monitoring with powerful seismic vibrators and MHD generators Provides historical background for previous studies of seismically active zones Covers the theory and technology of active monitoring, including signal processing, data analysis, novel approaches to numerical modeling, and interpretation Discusses case histories and presents the results of worldwide, regional active monitoring experiments Thoroughly updated to include recent developments, such as updates relating to carbon capture and storage, microgravity, InSAR technologies, geodesy, reservoir monitoring, seismic reflection, and more

Time Lapse Approach to Monitoring Oil, Gas, and CO2 Storage by Seismic Methods delivers a new technology to geoscientists, well logging experts, and reservoir engineers, giving them a new basis on which to influence decisions on oil and gas reservoir management.

Named ACROSS (Accurately Controlled and Routinely Operated Signal System), this new evaluation method is presented to address more complex reservoirs, such as shale and heavy oil. The book also discusses prolonged production methods for enhanced oil recovery. The monitoring of storage zones for carbon capture are also included, all helping the petroleum and reservoir engineer to fully extend the life of a field and locate untapped pockets of additional oil and gas resources. Rounded out with case studies from locations such as Japan, Saudi Arabia, and Canada, this book will help readers, scientists, and engineers alike to better manage the life of their oil and gas resources and reservoirs.

Benefits both geoscientists and reservoir engineers to optimize complex reservoirs such as shale and heavy oil Explains a more accurate and cost efficient reservoir monitoring technology called ACROSS (Accurately Controlled and Routinely Operated Signal System) Illustrates real-world application through multiple case studies from around the world

This book provides a comprehensive characterization of high-temperature geothermal fields worldwide, encompassing diverse geological settings such as extensional and contractional　tectonics, silicic and mafic crustal regions, hypersaline and low-salinity fluid environments, and both brittle and ductile lithospheric layers. It also details current geothermal exploration and development efforts in Japan.Emerging exploration technologies, including Full-waveform Inversion (FWI), Distributed Temperature Sensing (DTS), and Distributed Acoustic Sensing (DAS), are introduced and discussed in the context of their practical applications. A central challenge in geothermal development remains the accurate identification of viable targets for production and reinjection wells, as exploratory drilling entails significant costs. Accordingly, this book places special emphasis on target identification strategies, setting it apart from other works in the field.While global in scope, this book primarily focuses on geothermal development in Japan and features field-based case studies related to well targeting. Authored and reviewed by experienced geothermal engineers, it serves as a valuable resource for professionals engaged in geothermal exploration and reservoir engineering.
