Oil migration in shale formations across multiple scales from nanometers to meters, a topic
without receiving sufficient attention, is of great significance to the accumulation and …

The large-scale hydraulic fracturing technology is commonly employed to significantly
improve oil recovery in shale. An exceptional phenomenon from many field tests is worthy of …

Abstract The Middle Permian Lucaogou Formation in the Jimusaer Sag is a hotspot for
exploring and developing lacustrine tight oil in the Junggar Basin, NW China. In this study …

The heterogeneity of lithofacies is a pivotal factor influencing the shale oil potential. A
comprehensive understanding of the intricate influence of rock complexity on hydrocarbon …

Abstract The Middle Permian Lucaogou Formation in the Junggar Basin, China is a typical
tight oil reservoir. Thin sections, helium porosity and permeability, X-ray diffraction, X-ray …

The features of pore and throat structure of an unconventional reservoir are very complex
due to multiscale pore-throat size and various pore types and thus hard to characterize. In …

The tight reservoir property and oil accumulation are greatly affected by the complexity and
heterogeneity of pore structure. Fine-grained, mixed sedimentary formation samples from …

The complexity and diversity of reservoir characteristics, including strong heterogeneity,
complex pore structures, distinct pore size distributions, and various fluid occurrences, in …

The Gaotaizi reservoir in the Qingshankou Formation, northern Songliao Basin is one of the
most potential tight oil targets in China and it is underlain directly by the OM-rich shales of …

Although significant progress has been made in the tight gas exploration and development,
there is still a limited understanding of the fluid charging and hydrocarbon accumulation in …
