Factors influencing microstructure and porosity in shales of the Wufeng-Longmaxi formations in northwestern Guizhou, China

Journal of Petroleum Science and Engineering, 2020
Abstract Thickness marine shale of Paleozoic Wufeng-Longmaxi Formations is deposited in the northwestern Guizhou province, which borders on the shale gas production area in southeast Sichuan Basin. However, few studies have been performed to characterize shale gas reservoir of the Wufeng-Longmaxi Formations in this area.

Fracability Evaluation of Shale of the Wufeng‐Longmaxi Formation in the Changning Area, Sichuan Basin

Acta Geologica Sinica - English Edition, 2019
The fracturing technology for shale gas reservoir is the key to the development of shale gas industrialization. It makes much sense to study the mechanical properties and deformation characteristics of shale, due to its close relationship with the fracability of shale gas reservoir.

Dynamic Elastic Properties Measurement and Analysis of Wufeng-Longmaxi Formation Shale in Sichuan Basin

82nd EAGE Annual Conference & Exhibition, 2020
Summary Detailed experimental studies on the seismic properties of shale samples from different reservoirs have been conducted both in the laboratory and in situ under different conditions. In a previous study, Johnston and Wang (1981) measured the ultrasonic velocity anisotropy of Cretaceous shale in the Willison basin under undrained conditions ...

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 ...

Shale gas potential in China: A production forecast of the Wufeng-Longmaxi Formation and implications for future development

Energy Policy, 2020
Abstract Developing the abundant shale gas in China is a potential means to address the country’s challenges in air pollution and carbon emissions. The purpose of this paper is to evaluate the production potential of the most promising shale gas play—the Wufeng-Longmaxi Formation (WL) in China.

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

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.
