註釋Fluvial systems and their associated deposits host globally important mineral deposits, water reserves and hydrocarbons. Crucial to the extraction of these resources is an understanding of heterogeneity distribution within deposits of fluvial systems. To constrain and predict heterogeneity distribution within fluvial deposits, outcrop data together with lidar and drone derived virtual outcrop models have been collected from the Salt Wash Distributive Fluvial System (DFS) in Utah and Colorado. The study records an analysis of sedimentary architecture, facies distribution and intra-channel heterogeneity of five study sites within the proximal, medial and distal reaches of the Salt Wash DFS. Specifically the fluvial style, lateral variability of fluvial architecture, intrachannel and overbank ratio, grainsize, channel body and storey width:thickness ratios and intrachannel heterolthics at outcrops considered representative of the proximal, medial and distal portions of a DFS have been documented. Data from the study sites have been used to generate 3D reservoir models. The models have been subject to flow simulation to better understand the significance of hetergenity variability within fluvial reservoirs at an 'inter-well' scale (approximatley 0.1 km2).
