Opening of Bedding-Parallel Fractures in the Shale Oil Reservoirs of the Paleogene Funing Formation, Subei Basin, China

Energies
Bedding-parallel fractures represent a crucial flow-path network in shale oil reservoirs, yet their timing of opening and driving mechanisms remain subjects of long-standing debate. This study investigates the origin and opening mechanisms of bedding-parallel fractures within the Paleogene Funing shale oil reservoir of the Huazhuang area, Subei Basin ...

Identification and Sedimentary Model of Shallow-Water Deltas: A Case Study of the Funing Formation, Subei Basin, Northeast China

Minerals
Shallow-water deltas are not only a hot spot for sedimentological research but also a key target for oil and gas exploration. In this paper, taking the third member (E1f3) of the Funing Formation in the Upper Jurassic as an example, based on observations made from core samples, well logging, cathode luminescence characteristics, and analytical assays ...

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 ...
