The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.

Prediction of Fault and Fracture Density From Seismic Attributes and Machine Learning Models Calibrated With Borehole Image Logs

Basin Research, Volume 38, Issue 3, May–June 2026.
This study integrates post‐stack seismic attributes with a CNN‐based workflow to characterize sub‐seismic deformation in shale gas reservoirs. A near‐linear correlation is established between seismic characterization methods and borehole deformation counts.

Micro scopic heterogeneity and mechanical anisotropy of the laminated shale in Longmaxi Formation

地质科技通报, 2021
As a clean energy, the commercial development and utilization of shale gas affect the global energy landscape. The microscopic heterogeneity and mechanical anisotropy of laminated shale have crucial significance for studying wellbore stability and the hydraulic fracture (HF) geometry.

Asperity‐Driven Cascading Rupture of a Mw 1.6 Induced Microearthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Studies of small earthquake (M < 2) rupture processes traditionally rely on simplified models that assume symmetric slip or point sources. Using an exceptionally dense seismic network and empirical Green's function (EGF) analysis, we investigate the complex rupture of a Mw 1.6 microearthquake induced by hydraulic fracturing.

Microscopic time‐dependent mechanical behavior of shale derived from nanoindentation

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 160-175, March 2026.
This study conducted grid nanoindentation creep tests to systematically analyze the microscopic creep behaviors of shale. Based on the analysis of creep strain rate sensitivity, the primary mechanism of microscopic creep in shale was found to be the extension and closure of microcracks.

Mechanisms of CO2 Fracturing and Flooding for Enhanced Shale Gas Recovery: A Review

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Against the backdrop of the “Dual Carbon” strategy, CO2 pressure flooding technology has emerged as a core pathway for synergistically enhancing shale gas recovery and achieving carbon reduction, owing to its unique capabilities in competitive adsorption displacement, fracture network enhancement, and geological storage. To systematically elucidate the
