To predict the facies distribution of the fluvial deposits that gave origin to the Bajo Barreal Formation a Stratigraphic Forward Model (SFM) was built by simulating the dynamic sedimentary processes of erosion, transport and deposition and the basin structural evolution through geological time. Based on the paleo topographic reconstruction at the top of Castillo Formation, the sedimentary processes that gave rise to the Bajo Barreal Formation from 96 My to 71 My were simulated using the following processes: a) diffusion; b) steady flow; c) tectonic events; d) accumulation of sediments from volcanic events deposits; e) compaction. Additionally, an analysis of multiple variables that control the aforementioned processes was carried out being the most relevant: diffusion coefficient, transportability coefficient, average water supply in river channels, subsidence and its variability in time-space, sediment accumulation rate, and compaction rate. The resulting 4D confirms the more favorable reservoir petrophysical values in the top of the Lower Member of the Bajo Barreal Formation. The decrease in petrophysical quality in the upper section could be related to the increase in the pyroclastic material that started intensely at 91 My, added to an increase in the accommodation space where the shales are interspersed with pyroclastic and few sand horizons, representing marsh and alluvial plain deposits. https://biblioteca.iapg.org.ar/ArchivosAdjuntos/Conexplor2022/Estratigrafìa-Análisis-Cuencas/estratigrafia-y-analisis-de-cuencas12.pdf CONGTP Dominguez, Silvia 195987 195987 BVIAPG BVIAPG 2026-03-06 0 068.82 553.28 C62 15730 200068405 2026-03-06 00:41:20 ARCHIVO
