Numerical Simulation Study of CO2 Injection for Enhanced Recovery in Depleted Gas Reservoirs

Engineering Reports, Volume 7, Issue 5, May 2025.
This study investigates CO2 injection for enhanced recovery in the Wolonghe depleted gas reservoir in the Sichuan Basin using CMG and TOUGH simulations. It examines changes in reservoir temperature and pressure at Well 47 under varying CO2 injection rates, timings, and temperatures.

Effects of Periodic Normal Stress Oscillations on Frictional Properties of Simulated Natural Fault Gouges Under In Situ P‐T Conditions

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Induced earthquakes are occasionally associated with stress oscillations resulting from periodic industrial activities. Yet, the effects of stress oscillations on fault friction under realistic subsurface conditions are not fully clear. We conducted normal stress oscillations experiments using simulated fault gouges derived from the major ...

Characteristics of Natural Fractures in an Ultradeep Marine Carbonate Gas Reservoir and Their Impact on the Reservoir: A Case Study of the Maokou Formation of the JLS Structure in the Sichuan Basin, China

, 2021
The primary gas layer of the Maokou Formation of the JLS structure in the Sichuan Basin is a typical pore-fracture carbonate gas reservoir. Natural fractures (mainly tectonic fractures) serve as the critical factor in improving the reservoir’s physical ...

Anatomy of the Emeishan Mantle Plume Head: Insights From New Geochronologic, Geochemical, and Geologic Data

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 9, September 2024.
Abstract The link between mantle plumes and the formation of large igneous provinces (LIPs) is well established although the anatomy of these remains equivocal. Recent experimental studies and geophysical data suggest that the mantle plume head is more likely to be irregular and asymmetric, rather than an axisymmetric flattened disk. The Emeishan large

Mantle Plume‐Lithosphere Interactions Beneath the Emeishan Large Igneous Province

Geophysical Research Letters, Volume 51, Issue 2, 28 January 2024.
Abstract The formation of large igneous provinces (LIPs) has been widely believed to be linked to mantle plume activity. However, how the plume modifies the overlying lithosphere, particularly its compositional structure, remains uncertain. Here, we characterize the deep thermochemical structure beneath the Emeishan LIP (ELIP), which is a well‐known ...

Study of Ground Vibration Site Effects on Substation in Inhomogeneous Strata

Shock and Vibration, Volume 2024, Issue 1, 2024.
A large substation confronts the risk of frequent tectonic earthquakes with a relatively high magnitude, thus it is necessary to analyze the seismic response of the site. To provide a reference for the seismic analysis of this substation, the seismic response of the substation site was investigated.
