Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory

open access: yesDeep Underground Science and Engineering, EarlyView.
The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.

Evaluation of the CO2 storage potential in CO2‐enhanced oil recovery: A case study of the Subei Basin, Jiangsu Province, China

open access: yesDeep Underground Science and Engineering, EarlyView.
CO2‐enhanced oil recovery (CO2‐EOR) is an economically viable carbon capture, utilization, and storage (CCUS) technique that is widely practiced and contributes significantly to the achievement of carbon‐neutral cities. However, few studies have been conducted on CO2‐EOR source–sink matching involving different emission sources, different carbon ...

Characterization of the permeability evolution of hard and soft rocks under hydro‐mechanical coupling conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Hydrogen sulfide in underground hydrogen storage sites: Implication of thermochemical sulfate reduction

open access: yesDeep Underground Science and Engineering, EarlyView.
A one‐dimensional diffusion‐based mass transport model was built using PHREEQC to highlight the potential challenges posed by thermochemical sulfate reduction (TSR) in depleted gas fields. The results obtained indicated that the presence of iron minerals (pyrite and hematite) is crucial for H2S generation through TSR reactions.

Study on the diffusion and migration law of CO2 sequestrated in abandoned coal mine goaf

open access: yesDeep Underground Science and Engineering, EarlyView.
The goaf of an abandoned coal mine, endowed with expansive fracture spaces and an abundance of residual coal, can be capable of sequestrating substantial quantities of CO2. The residual coal is the principal medium for the sequestration of CO2 in the form of adsorption and the amount of sequestration is considerable.
