We wish to better compare accelerometer (acceleration) and geophone (velocity) data to distributed acoustic sensing (DAS) fibre-optic data (strain-rate). 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).
