The Rio Claro Formation, Tertiary-Quaternary age, is composed of unconsolidated sediments deposited by fluvial systems. In Paulínia (SP) region geological studies comprising sedimentological, structural and geomorphological aspects indicate that the Rio Claro Formation is constituted by deposits of a meandering fluvial system. Data from SPT drillings were used to obtain sedimentary textural information in order to generate stochastic stratigraphic models. Particle size analysis was carried with the core samples which resulted in the distinction of five litofacies, three of which can be grouped into only one mudstone unit. The other two facies represent channel belt facies, being clayey sands and medium to coarse sands. Geostatistical modeling of the stratigraphic architecture followed together with correlation of analogue outcrop data and conceptual models for this type of depositional system. 100 models were generated with the SPT drillings and 50 models were generated with data from an analogue outcrop, which allowed constraining of both simulation sets to the depositional model given for the region. T-PROGS methodology has good applicability in simulating stratigraphic frameworks and its inherent limitations may be approached with parallel studies, such as stochastic modeling of analogue outcrops or geophysical methods
