The shale lithofacies shows obvious heterogeneity during the Late Ordovician-Early Silurian
in the Upper Yangtze area, SW China. To elucidate the Wufeng-Longmaxi shale lithofacies' …

Abstract The Wufeng–Longmaxi shales, which were deposited during the Ordovician–
Silurian transition in the southern Sichuan Basin, exhibit distinct lithofacies transitions. The …

Abstract The Upper Triassic Ma'antang Formation is not only an important set of source
rocks in the Sichuan Basin but may also be a successor for shale gas in China. In this study …

The exploration and development of deep marine shale gas has made significant
breakthroughs, but factors influencing gas contents of deep marine shale are elusive, and …

To investigate the origin of quartz and its effect on shale reservoirs in the Dalong Formation,
we conducted a thorough analysis of shale samples using various techniques including …

The shales of the upper Permian longtan formation (LTF) in the central Hunan area have a
wide distribution and high organic matter content. Unlike the anoxic conditions of marine …

Fractures in organic-rich shale affect the evolution of permeability and control shale gas
preservation. We characterize fracture attributes in the Qiyue-Huaying Fold-Thrust belt in the …

Quartz is an important mineral component of shale. In order to explore the influence of
quartz content on the mechanical properties of shale, this article conducted numerical …

Various types of pores, including organic and inorganic variations, exhibit distinct impacts on
the storage capacity of shale gas reservoirs and play a significant role in shale gas …

Organic matter in depositional environment is the essential material for oil and gas
generation. Total organic carbon (TOC) is one of the important parameters for estimating the …
