The Porosity in Heterogeneous Carbonate Reservoir Rocks: Tectonic versus Diagenetic Imprint—A Multi-Scale Study from the Hyblean Plateau (SE Sicily, Italy)

The petroleum industry has always been pursuing highly exploitable gas fields, which are often hosted in carbonate rocks. However, carbonates heterogeneous and show different fabrics structures as the result of sedimentation various environments, subsequent diagenesis deformation. In this study, a multi-scale multidisciplinary approach performed on classical reservoir rocks from subsurface Hyblean Plateau (Sicily, Italy). We aim at unravelling important debated role tectonic diagenetic (mainly fractures well stylolites) enhancing or reducing porosity. Black shales, limestones, laminites intertidal environment represent main lithologies. Structure cross-cutting relationships record stages basin geological history, related to evolution area. Our results that porosity is uncommonly lightly affected by faults, because their mineralization, whereas stylolites, considered barriers fluid flow, certain Therefore, we want highlight importance analysis heterogeneously porous, fractured- stylolite-rich rocks, our study aspires boost other similar studies energy transition times.
