Abstract

Two intersecting, one km long, high resolution seismic reflection surveys mapped a known segment of the Dalmeny aquifer near Saskatoon, Saskatchewan, Canada (Figure 1). The long term objective of the investigation is two fold: 1) develop an imaging technique for mapping the 3-D extent and geological properties of shallow perched water reservoirs within the upper 200 m of glacial till deposits of the Canadian prairies, 2) image the structures, stratigraphic sequences and establish primary 3-D acoustic properties of the glacial till. Data acquisition parameters were designed by wave-equation modelling of the borehole based crosssection of the aquifer. This single detection based geophone array observed broad signal spectra and seismic images with unexpected details. Beyond the outline of the top and base of the shallow aquifer (< 50 m), the seismic images disclosed a number of thin irregular till deposits within the primary aquifer. In addition, the lateral extent of a buried valley aquifer was defined with significantly greater detail than was established from broadly spaced borehole information. A number of buried channels and multistacked depositional sequences were clearly delineated by both seismic profiles. The acoustic properties of the geologically distinct sequences are not significantly different, still they appear to be mappable by the detailed seismic survey.
