Abstract
Se presenta el flujo de trabajo de investigación utilizado en el proyecto SOSGAS, encaminado a la Evaluación de Calidad como Reservorio de CO2
y H2
verde de formaciones clásticas Mesozoicas y Cenozoicas heterogéneas de origen fluvial y deltaico de la Meseta Ibérica y
de las Cuencas del Ebro y de Graus-Tremp. Mediante el estudio integrado de datos de afloramiento y subsuelo (a partir de sondeos traseros a los afloramientos) se elaboran modelos conceptuales de cada
ejemplo estudiado que describen las variaciones de las heterogeneidades sedimentarias y que conducen a la modelización estática de
los distintos geocuerpos y de sus propiedades petrofísicas. Finalmente,
la modelización dinámica basada en experimentos de simulación de
inyección de gas (CO2
e H2
) en los modelos estáticos nos permite analizar la sostenibilidad de proyectos de geo-almacenamiento de estos
fluidos clave en la transición energética
The research workflow developed in the SOSGAS project is presented, aimed at the Quality Assessment as a reservoir of CO2 and green H2 of heterogeneous Mesozoic and Cenozoic fluvial and deltaic formations of the Iberian Meseta and the Ebro and Graus-Tremp Basins. Through the integrated study of outcrop and subsurface data (derived from boreholes drilled behind the outcrops), conceptual models are developed for each examined case, describing variations in sedimentary heterogeneities. These models contribute to the static modelling of different geobodies and their petrophysical properties. Finally, dynamic modelling, based on gas injection simulation experiments (CO2 and H2 ) into static models, enables the analysis of the sustainability of geo-storage projects for these key fluids in the energy transition
