Langenberg et al. (2002) purport to identify discrete ‘channel complexes’ in outcrop exposures along the Steepbank River of northeastern Alberta, and they claim to have extrapolated these channel complexes into the nearby subsurface. They have used the resulting stratigraphic correlations as input for a seismic model constructed using ray-tracing techniques. The seismic model demonstrates the viability and utility of high resolution seismic over the shallow deposits of the Athabasca Oil Sands.
Two major issues in Langenberg et al. (2002) deserve comment, however.
The seismic modeling techniques used by Langenberg et al. (2002) do appear to support their conclusion, from a...
