We consider this to be best accomplished by converting accelerometer and geophone data to strain-rate, as strain or strain-rate is what is of most interest to engineers. We propose a method to convert from velocity to strain-rate, and provide examples from two seismic surveys were acquired at the Containment and Monitoring Institute’s Field Research Station (CaMI.FRS; In Newell County, Alberta, Canada) with Vibroseis sources; 1) A multi-azimuth walk-away vertical seismic profile (VSP) that was recorded on downhole threecomponent (3C) geophones, 3C accelerometers, straight and helically wound optical fibre, and 2) A seismic survey that was recorded on 3C geophones on the surface as well as an experimental buried directional optical fibre sensor (Figure 1).Presentation Date: Monday, October 12, 2020Session Start Time: 1:50 PMPresentation Time: 3:05 PMLocation: Poster Station 6Presentation Type: PosterKeywords: DAS (distributed acoustic sensors), multicomponent, vertical seismic profile (VSP), 3C, fiber-optic sensorsPermalink: https://doi.org/10.1190/segam2020-3427754.1FiguresReferencesRelatedDetailsCited byImaging near-surface S-wave velocity and attenuation models by full-waveform inversion with distributed acoustic sensing-recorded surface wavesWenyong Pan, Luping Qu, Kristopher A.
