ABSTRACT In 2015 a time-lapse buried receiver 3C/2D seismic experiment was performed in the heavy oil area of NE Alberta, Canada. The purpose was to determine if on-going reservoir monitoring was feasible beneath a thick layer of muskeg. 3C analog geophones and digital sensors were installed at surface, 3m and 9m along with dynamite sources at 9m. Shot points were doubled at each source location in order to acquire data during winter conditions and also during the following summer.
The test was in response to poorly imaged seismic stacks and inversions from previously acquired 3C/3D surface seismic data. High quality time-lapse PP and PS images were produced from the 2D data when both the dynamite sources and receivers were buried to 9m depths. Recording PP and PS reflections that bypass the absorptive near-surface muskeg layer with buried receivers and sources facilitates time-lapse multicomponent seismic monitoring in this area.
