Important Aspects of Acquiring Distributed Acoustic Sensing (DAS) Data for Geoscientists

Fiber-optic distributed acoustic sensing (DAS) is a technology used for many strain measurement applications, including seismic monitoring. Because it is relatively new to the market, most geoscientists are unfamiliar with the details of the technology, but nevertheless are required to make important acquisition parameter decisions such as the type of fiber-optic glass to use, the deployment method for the fiber-optic cable, the gauge length, and how to diminish the effect of optical noise. This chapter provides a non-theoretical, practical approach to making these decisions in order to obtain high-quality DAS data sets.
