... in the Aquistore case in which the data fold is generally low (acquired with a sparse receiver array) and the source of the time-lapse signal is small (36 kt of CO 2 within a 10 m thick zone at a depth of 3200 m). As the definition of Nrms implies, it is a means of “normalizing” the measurement of amplitude...

Figure 5 compares 3D VSP data acquired using 57 clamping geophones with simultaneously recorded DAS data with 1384 channels. Whereas both data provide useful...

...Don J. White; Lisa A. N. Roach; Brian Roberts ABSTRACT A sparse areal permanent array of buried geophones was deployed at the Aquistore CO 2 storage site in Saskatchewan, Canada. The purpose of this array is to facilitate 4D seismic monitoring of CO 2 that is to be injected to the deep subsurface...
