Abstract

Summary

This study evaluated Distributed Acoustic Sensing (DAS) for subsurface imaging by comparing it with geophones. In a simplified Earth model, DAS provided superior spatial resolution of a shallow aquiferous unit due to its dense sampling but exhibited lower vertical resolution for deeper layers due to seismic energy attenuation. In a complex faulted model, geophones more clearly delineated fault edges, while DAS showed increased migration artifacts due to fiber directivity. These findings highlighted DAS’s strengths in high-resolution shallow imaging but also its limitations in vertical resolution and fault boundary detection compared to geophones.
