Presents the latest advances in borehole distributed acoustic sensing and diverse applications for subsurface geophysics
Borehole geophysics involves measuring, imaging, and monitoring subsurface structures and activities by putting instruments into wellbores. Distributed acoustic sensing (DAS) technology is emerging as an effective and reliable tool in borehole geophysics because optic fiber cables deployed at depth can produce high-quality data and images, even in harsh high-temperature and high-pressure environments.
Distributed Acoustic Sensing in Borehole Geophysics is a comprehensive handbook on cutting-edge advances in borehole DAS technologies and their practical applications across geophysics.
Volume highlights include:
* Summary of evolution of DAS technologies and their primary applications
* New developments in borehole DAS instrumentation and modeling
* Examples of DAS data acquisition and processing in different contexts
* Variety of imaging methods and techniques for integration of images with other data
* Applications of borehole DAS systems, including monitoring earthquakes and hydraulic fracturing operations
* Case studies of borehole DAS projects at diverse sites around the world, ranging from glaciers to geothermal fields
The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
