As invited speaker for the "Best of Petroleum Geoscience" session (7.07), We present a summary of the work by Fitch et al. (2014), investigating the relative impact of stratigraphic and sedimentological heterogeneities on flow behaviour and simulated recovery under two production strategies, which promote a dominance of either horizontal or vertical flow. Integrated flow simulation and experimental design techniques were used to investigate the first-order impact of stratigraphic and sedimentological heterogeneities on simulated recovery in carbonate reservoirs. Heterogeneities controlling the value of rock properties, and the volume and lateral continuity of EOD-belts were found to be key controls on flow behaviour in displacements dominated by either horizontal and vertical flow. The significance of heterogeneities controlling vertical flow paths, such as continuous, impermeable barriers and permeability anisotropy increases when vertical flow dominates.
