Previous HitReservoirNext Hit flow Previous HitsimulationNext Hit involves two aspects: a functional model (flow equations and numerical methods) and a representation model (related to the Previous HitreservoirNext Hit description). Commonly, the latter is the most critical one. Previous HitReservoirNext Hit representation is different from Previous HitreservoirNext Hit characterization, since its main issue is not describing the Previous HitreservoirNext Hit in the most exhaustive and detailed form, but rather the challenge of incorporating the relevant information into the flow Previous HitsimulationNext Hit model. It has to consider the syntax of the flow Previous HitsimulationNext Hit methods and the relative impact of geological (and fluid) characteristics on the Previous HitsimulationNext Hit results. Previous HitReservoirNext Hit representation constitutes the bridge between Previous HitreservoirNext Hit characterization and flow Previous HitsimulationNext Hit.

This paper presents selected results from several studies of turbidite reservoirs, in which the following steps were taken: (1) the identification and representation of critical depositional heterogeneities; (2) assignment of transmissibility multipliers across partially sealing faults; and (3) incorporation of production data in Previous HitreservoirNext Hit flow models. Seismic geomorphology analysis integrated with outcrop studies was used to identify the critical depositional heterogeneities, whose impact on fluid flow was tested using a series of synthetic models. Faults patterns were identified at the subsurface and their impact evaluated using in situ stress information, production data and outcrop analogs. Finally, observed production and pressure data were integrated using assisted history matching.

Such an integrated approach increased the precision of flow Previous HitsimulationNext Hit models. The Previous HitstudyNext Hit clearly shows that Previous HitreservoirNext Hit flow modeling, and hence the understanding and adequate representation of Previous HitreservoirTop connectivity, more than a multidisciplinary task, is an interdisciplinary task, in which is essential to fill the gaps between different disciplines.
