Abstract
The effects of small-scale structure are frequently ignored in reservoir simulation, although they may have a significant effect on hydrocarbon recovery. In this paper the effect of small-scale geological structure on single-phase flow is investigated using a model of a cross-bedded unit to determine which factors have the greatest effect on cross-flow. In addition, a range of other types of bedding are considered, including models with stochastic variation. In general, the geometry of the sedimentary structure has a significant effect on flow. The cross-flow is greater (and therefore tensors are more likely to be necessary) when the angle of the laminae is large relative to the pressure gradient (up to 45°), when the permeability contrast between laminae is large, or when the structure is asymmetric. -from Authors
