The main geological factors controlling the Wufeng- Longmaxi shale gas content

, 2022
Changning and Fuling are two of the best-known shale gas fields in China, located at two different depositional centers of the Upper Ordovician Wufeng Formation to the lower Silurian Longmaxi Formation in the Sichuan Basin. However, there are significant

Stratigraphic framework of the Wufeng-Longmaxi shale in and around the Sichuan Basin, China: Implications for targeting shale gas

Energy Geoscience, 2020
Stratigraphic division and correlation are crucial for the identification of sweet spots and drilling design of shale gas. In this study, a stratigraphic division and correlation was carried out for the Wufeng-Longmaxi Formations in southern China from ...

Impact of Overpressure on the Deep Shale Pore System─A Case Study of Wufeng–Longmaxi Formations from the Southern Sichuan Basin

ACS Omega, 2023
This study investigated the effect of overpressure on the deep shale pore system in the Wufeng-Longmaxi Formation (WLF), a well-established shale gas reservoir in the southern Sichuan Basin, China. The Y1 well was drilled to explore deeper overpressured sections of the basin.

Dynamic elastic properties of the Wufeng–Longmaxi formation shale in the southeast margin of the Sichuan Basin

Journal of Geophysics and Engineering, 2014
In spite of the growing interest in Late Ordovician to the Early Silurian Wufeng–Longmaxi black shale for gas production in the southeast of the Sichuan Basin, little data is available on the acoustic properties of these shale reservoirs. The dynamic elastic properties of a suite of shales from this formation with different organic matter content were ...

Shale petrofacies division of Wufeng-Longmaxi formations in Sichuan Basin and its periphery

Shiyou shiyan dizhi, 2020
The research of shale petrofacies is significant for the exploration of shale gas "sweet spots". Different petrographic division schemes have been proposed but no consensus has been reached. This paper has studied the criteria and boundary values of the petrographic classification reference parameters of the Upper Ordovician Wufeng-Lower Silurian ...

Differential Reservoir-Forming Mechanisms of the Lower Paleozoic Wufeng-Longmaxi and Niutitang Marine Gas Shales in Northern Guizhou Province, SW China: Theories and Models

Energies, 2022
Fine dissection of microscopic pore structure variations between the Niutitang Formation and the Wufeng-Longmaxi Formation will help to improve the understanding of the underlying geological theory of shale gas in northern Guizhou Province.
