In some fields, it may be necessary to prepare separate structural and formation fluid models in addition to depositional and diagenetic models (Figure 2). In most reservoirs, however, structural and formation fluid factors are not the major controls on fluid flow behavior, and the heterogeneities observed can be incorporated into the diagenetic model. | In some fields, it may be necessary to prepare separate structural and formation fluid models in addition to depositional and diagenetic models (Figure 2).
