Abstract:

A method for computing attenuation from seismic data. The method may include measuring one or more seismic events with a distributed acoustic sensing (DAS) system to form a well log of one or more traces. The method may further include isolating a first seismic event with a tapered windowing function, performing a spectral ratio of two or more pairs of traces in the well log, identifying a velocity at each of the one or more traces in the well log, identifying an analytic correction for a gauge of the DAS system, and applying the analytic correction to the spectral ratio to form a corrected spectral ratio. Additionally, the method may include identifying a slope of the corrected spectral ratio for at least a part of the well log, converting the slope to a Q value, and identifying one or more formation properties in a formation from the Q value.
