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 ...

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.

Pressure Evolution Mechanism of Marine Shale Reservoirs and Shale Gas Accumulation Model: Evidence from Fluid Inclusions in the Wufeng–Longmaxi Formation in the Basin Margin Structural Transition Zone in Northern Guizhou Province, China

, 2023
The Wufeng–Longmaxi Formation in northern Guizhou Province is the dominant shale gas exploration and development strata in China. This study investigates the Shixi and Daozhen synclines, which are located in the basin margin transition zone.

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 ...

Precise Characterization of Fluid Logging Responses in Complex Shale Reservoirs: A Case Study From the Hongxing Area, Eastern Sichuan Basin

Geofluids, Volume 2026, Issue 1, 2026.
Precise characterization of fluid‐sensitive logging responses in complex shale reservoirs is very important. It is essential for quantitative formation evaluation and development optimization. Based on a case study of the shale gas reservoir in the second member of the Wujiaping formation (hereinafter referred to as the Wu‐2 Member) in the Hongxing ...
