Cenozoic exhumation and shale-gas enrichment of the Wufeng-Longmaxi formation in the southern Sichuan basin, western China

Marine and Petroleum Geology, 2021
Abstract Based on low-temperature thermochronological data (i.e., apatite fission-track (AFT) and (U–Th)/He (AHe)), structural evolution, burial and thermal history, this paper examines the relationship of multi-stage evolution between the upper Ordovician Wufeng and lower Silurian Longmaxi formations (i.e., the WL formation) and rapid exhumation at ...

Characterization and origin of the Silurian Wufeng-Longmaxi Formation shale multiscale heterogeneity in southeastern Sichuan Basin, China

Interpretation, 2015
Abstract Shale heterogeneity is important for micro- to macroscale-quality reservoir prediction. We evaluated the multiscale heterogeneity in shale based on thin-section observation, field emission scanning electron microscope observation, low-pressure N2 adsorption analysis, mercury intrusion porosimetry, organic carbon analysis, and

Formation, Evolution, and Preservation Mechanisms of Overpressure in the Wufeng–Longmaxi Shale, Changning Area, Sichuan Basin

Journal of Petroleum Geology
ABSTRACT Abnormally high pressure is widely developed in the Wufeng–Longmaxi (WF–LMX) reservoirs in the Changning (CN) area; however, the paleo‐pressure state, pressure evolution and genetic mechanisms during burial, and uplift remain unclear.

Shales in the Qiongzhusi and Wufeng–Longmaxi Formations: a rock-physics model and analysis of the effective pore aspect ratio

Applied Geophysics, 2017
The shales of the Qiongzhusi Formation and Wufeng–Longmaxi Formations at Sichuan Basin and surrounding areas are presently the most important stratigraphic horizons for shale gas exploration and development in China. However, the regional characteristics of the seismic elastic properties need to be better determined.

Shale gas‐bearing capacity and its controlling factors of Wufeng–Longmaxi formations in northern Guizhou, China

Geological Journal
Great progress has been made in marine shale gas of Wufeng–Longmaxi formations in the Sichuan Basin. However, shale gas exploration in the complex structural belt around the Sichuan Basin still faces great challenges. In this study, shales of Wufeng–Longmaxi formations collected from the northern Guizhou were taken as the studied target, organic matter

Quantitative characterization of nano-scale pores in shale reservoirs of Wufeng-Longmaxi formation based on image processing

2020
In this paper, we conducted image processing on FE-SEM images of representative shale samples from WX-1 well in the north-east Chongqing area. The structural parameters and proportions of major pore types were determined and analyzed following a workflow consisting of nano-scale images acquisition, image processing, pore-network evaluation and ...
