Standard flow cells to incorporate small-scale heterogeneity (crossbedding) in a reservoir model

Small-scale heterogeneities like crossbedding hamper fluid flow and cause oil to be capillary trapped at the intersections of coarser to finer lamina. These effects are fairly well established, but less well established is the method to construct an adequate flow cell model containing critical hydraulic properties like bed-shape and -size, lamina-shape, -angle and boundaries. Nor is it trivial how to obtain those features from well and core. We therefore propose to systematically describe geometry and distribution of beds. To this end we make use of standard flow cell models that a priori contain all elements and boundaries of beds for a number of bedding types.
