¿Tiene la Sedimentología un papel en la transición energética? Una propuesta

Abstract

El proyecto SOSGAS tiene por objeto calibrar el impacto de la heterogeneidad sedimentaria inherente a formaciones fluviales y deltaicas en el geo-almacenamiento sostenible de CO2 y H2 verde. Se han seleccionado 6 ejemplos mesozoicos y cenozoicos en la Meseta Ibérica, la Cuenca del Ebro y la Cuenca de Graus-Tremp a los que se aplica el flujo de trabajo OBO. Con esta base de datos de afloramiento y subsuelo se construyen modelos estáticos 3D de distribución de facies reservorio y sello y de propiedades petrofísicas, y finalmente se simula la inyección de los fluidos. Diferentes hipótesis de conectividad entre litofacies porosas y de distribución de los sellos conducen a diferentes escenarios de dinámica de fluidos y de entrampamiento. Con este proyecto iniciamos una línea de investigación que permitirá evaluar la validez de la sedimentología para contribuir al reto social de la transición energética.

The SOSGAS project aims to gauge the impact of sedimentary heterogeneity inherent to fluvial and deltaic formations on the sustainability of a possible geo-storage of CO2 and green H2. 6 Mesozoic and Cenozoic examples have been selected in the Iberian Meseta, the Ebro Basin and the Graus-Tremp Basin to which the OBO workflow is applied. Using this outcrop and subsurface database, 3D static models are constructed to reproduce the distribution of reservoir and seal facies and petrophysical properties, and finally fluid injection is simulated. Different hypotheses of connectivity of porous lithofacies and seal distribution lead to different scenarios of fluid flow dynamics and trapping. With this project, we are initiating a line of research that will make it possible to assess the validity of sedimentology in contributing to the social challenge of the energy transition.
