Multicomponent seismic surveys at Sibbald Flats, Alberta

Robert R. Stewart and Don C. Lawton


We conducted a 3C seismic survey, using vibrators, over a 5 km line in the Sibbald Flats area some 40 km west of Calgary. The line, shot in October 2003, is intended to image a Triangle Zone structure that can contain hydrocarbon reservoirs. In addition, we acquired data to test the "dragged array" concept. In these tests, we recorded numerous individual vibrators shaking at various parts of the shot interval as well as simultaneous shaking. The 3C data acquired look promising for both PP and PS analysis. Another dynamite line will be acquired at the same location in late November, 2003. This additional line should provide data to compare dynamite versus vibrators as sources for the generation of PS sections.
