Impact of Paleoclimatic Variability on Shale Oil Enrichment in Deep to Semi-Deep Lacustrine Facies: A Case Study of the Second Member of the Funing Formation, Qintong Depression, Subei Basin, Eastern China. [PDF]

ACS Omega
Lacustrine depositional systems are more sensitive to climatic fluctuations than marine systems, producing significant stratigraphic and sedimentological heterogeneity that affects shale oil distribution. However, the mechanisms linking paleoclimatic variability to shale oil enrichment remain insufficiently constrained.

The Sedimentary Environment and Organic Matter Enrichment of the Second Member of the Funing Formation in the Gaoyou Sag, Subei Basin

Processes
The second member of the Paleogene Funing Formation (E1f2) in the Gaoyou Sag, Subei Basin, is a promising shale oil target, yet its organic matter (OM) enrichment mechanisms remain poorly understood. This study integrates petrological and multi-proxy geochemical analyses to investigate lithofacies, paleoenvironmental evolution, and OM enrichment of the

Pore Structure and Heterogeneity in the Lacustrine Shale of the Second Member of the Paleogene Funing Formation, Subei Basin, China

Minerals
Characterization of pore structure and heterogeneity is crucial for exploring and evaluating shale oil and gas resources. Existing methodologies exhibit various limitations, and intuitive, quantitative description techniques are lacking. To address these issues, shales from the second member of the Funing Formation (E1f2) in the Subei Basin were ...
