Resumo

From the geometrical, sedimentological and petrological characteristics derived from an outcrop and the core and well logging data of 4 boreholes in combination with 5 GPR lines (200 MHz), a 3D model of a layer of sandstone in TIBEM (Triassic of the Iberian Meseta, Spain) has been developed. The selected example corresponds to a meander belt. In it we have distinguished for modeling purposes the main highly sinuous channel, two successive point bars,multiple scroll bars and two chute channels, as well as a clay plug marking the phase of channel inactivity. The model obtained using the Petrel software shows fairly realistic heterogeneities within the reservoir, allowing the identification of areas with quite different values of porosity and permeability, controlled by the distribution of lithofacies among different subenvironments. The example reveals as an interesting outcrop analog to many fluvial reservoirs.
