Abstract Unconventional geo-resources are critical due to their important contributions energy production. In this transition and sustainability era, there is an increased focus on CO 2 -enhanced oil recovery (CO -EOR) geological storage (GCS) in unconventional hydrocarbon reservoirs, the extraction of hot fluid for through enhanced geothermal systems. However, these solutions can only be achie...

The success of shale oil exploration and production is highly dependent on the heterogeneous nature reservoir pore structure. Despite this, there remains limited research heterogeneity characteristics pores at different scales in lacustrine reservoirs factors that impact them. This study aims to quantitatively characterize multi-scale differences found Funing Formation Gaoyou Sag. Additionally,...
