Comparison of Geophone and Surface-Deployed Distributed Acoustic Sensing Seismic Data
The rapid and nonintrusive deployment of seismic sensors for near-surface geophysical surveys can make data acquisition more efficient, in a wide variety of environmental and surface-terrain conditions.
This paper describes the acquisition of near-surface data through the successful deployment of fiber optic cables operating in a distributed acoustic sensing (DAS) configuration, compared to data acquired using a traditional vertical geophone array.
Detection and characterization of fractures in reservoirs is important for maximizing hydrocarbon productivity and recovery efficiency. Seismic attributes like coherency and curvature that are derived from reflection seismic data are used to detect faults and fractures. In advanced seismic fracture detection technology, Automatic Fault Extraction from diffraction seismic data effectively detects finer scale features.
