Active Geophysical Monitoring (3^rd Ed.)

Active Geophysical Monitoring covers the praxis of active geophysical monitoring to a broad range of applications, including CCUS, hydrocarbon reservoir development and management, groundwater, earthquake monitoring, and more. The editors and contributing authors thoroughly examine the latest developments and technologies in this new edition. The text begins with an in-depth overview of active geophysical monitoring followed by a close look at active targets and the latest technology. The theory of data analysis and interpretation follows in detail. The text closes with fifteen case histories in signal processing as well as carbon capture and storage. This updated edition is an invaluable resource to geophysicists employing a range of monitoring applications.
