.... These tidal inputs increased reservoir heterogeneities primarily because of successive mud decantation periods and the many reactivation or erosion surfaces. Five main reservoir heterogeneities have been described on Steepbank River outcrops: mud accumulation during channel abandonment, mud drapes along...

... River, north of Fort McMurray, near the Suncor Steepbank Mine. We have identified at least four channel complexes based on stratal bounding surfaces, arrangement of exposed lithofacies, and consistent paleoflow patterns. The lower part of each channel complex contains medium to large-scale, trough...
