Abstract:  Heterogeneity in unconventional reservoirs occurs from basin-scale to the pore-scale, and capturing these heterogeneities through process-based geologic models is required for exploration and optimization success.  Variability occurs as a function of depositional environment, accommodation, and sediment supply and composition.  Understanding sediment transport in fine-grained sedimentary systems has seen a paradigm shift due to flume studies that show a significant bedload component in transport processes, resulting in heterogeneous interbedded and interlaminated deposits.  Whereas silty laminae can be attributed to partitioning phenomena during bedload transport of flocculated muds, the implications of interbedded muds and sands are less clear.  Because of potential bed erosion downstream of sand ripples, and the load imposed by sandy layers, one may wonder whether water-rich surface muds would be eroded prior to active sand accumulation or would collapse due to the added weight.  For interpreting ancient mudstone successions with sandstone interlayers this question is critical, because much…
