Shale geological features of Qiujiahe (Є1q) and Longmaxi (S1ln) Formation
2015The main purpose of this research paper is to compare Qiujiahe Formation (Є1q) and Longmaxi Formation (S1ln) in north Sichuan basin where shale gas exploration has not been fully researched, and hence represents the possibility of shale gas concentration under the complex geological conditions. Based on valid laboratorial analysis, there are optimistic

Elastic parameter inversion of Longmaxi Formation shale based on the least squares method
Arabian Journal of Geosciences, 2021Elastic parameters are important parameters in the study of shale anisotropy, exploration, and development, and their accuracy is of great significance. In this study, shale in the lower Silurian Longmaxi Formation of southeastern Chongqing was investigated by obtaining the acoustic velocity of the partial bedding angle through an acoustic transmission

Journal of Energy Resources Technology, Part B: Subsurface Energy and Carbon Capture
Abstract The Longmaxi Formation in the Western Chongqing Block of the Sichuan Basin holds significant potential for shale gas resources and has gradually become an important area for exploration and development. However, the challenges posed by high temperature, high pressure, and wellbore instability during the drilling of deep shale

Abstract A large, typical, marine, organic-rich shale is developed in the Ordovician Wufeng Formation-Silurian Longmaxi Formation in the Sichuan Basin, China, which has rich shale gas resources. This paper uses this type of shale as an example to analyze the influence of the depositional environment on the enrichment mechanisms and sedimentary ...

Journal of Earth Science, 2019
Shale gas resources have been regarded as a viable energy source, and it is of great significance to characterize the shale composition of different cements, such as quartz and dolomite. In this research, chemical analysis and the multifractal method have been used to study the mineral compositions and petrophysical structures of cements in shale ...

Controls on matrix permeability of shale samples from Longmaxi and Niutitang formations, China
Journal of Natural Gas Science and Engineering, 2016Abstract The Lower Silurian Longmaxi shale and the Lower Cambrian Niutitang shale are typical marine shales in China, promising for shale gas production, whereas the gas production from these two formations vary considerably because of the different flow properties determined by geology and lithology conditions.
