Rock grain-scale mechanical properties influencing hydraulic fracturing using Hydro-GBM approach

Lie Kong et al.

Summary: Rock cracking and fracturing have significant implications for geological applications. This study investigates the influence of rock grain-scale mechanical parameters on fluid-driven cracking behaviors and proposes a formulation to eliminate the mismatch between experimental and simulated shear cracking. The results provide valuable insights into the effects of rock grain-scale properties on hydraulic fractures and guide the selection and calibration of micro mechanical parameters in future modeling.

Hydraulic fracture height growth in layered rocks: Perspective from DEM simulation of different propagation regimes

Liuke Huang et al.

Summary: A study investigates the propagation of hydraulic fractures in layered rocks using 2D discrete element modeling. It finds that the stiffness and toughness ratio, as well as stress contrast, affect the height growth of the fractures. The propagation regime also plays a crucial role in the fracture propagation in layered rocks.

Parameter studies on the mineral boundary strength influencing the fracturing of the crystalline rock based on a novel Grain-Based Model

Song Wang et al.

Summary: The novel grain-based model (nGBM) composed of the Flat-Joint (FJ) and the SJ was proposed to solve the microcracking process of brittle rocks in the original GBM. The nGBM was established and calibrated based on properties of Alxa porphyritic granite, and simulation tests showed complicated relationships between mineral boundary properties and mechanical behaviors. This study provides valuable insights into the micromechanical damage process of crystalline rocks and serves as a reference for model calibration.

Development of microcracks in granitic rock by liquid CO2 fracturing

Seong Jun Ha et al.

Summary: In this study, hydraulic fracturing by liquid carbon dioxide (LCO2) and water in a granitic specimen was investigated to determine the micro-scale characteristics of generated microcracks. The results showed that LCO2 and water injection produced different fracture characteristics, with LCO2 requiring a greater fluid volume to generate a lower breakdown pressure. The developed microcracks were affected by the fracturing fluid and anisotropic properties of granitic rocks.

Influence of grain size on strength of polymineralic crystalline rock: New insights from DEM grain-based modeling

Jun Peng et al.

Summary: The research shows that the strength of rock increases with the grain size in the rock model, as larger grain size reduces the number of grain interfaces leading to higher rock strength. By degrading grain boundary parameters with increasing grain size, a plausible explanation is provided for the grain size effect on rock strength.

Fluid-driven micro-cracking behaviour of crystalline rock using a coupled hydro-grain-based discrete element method

Lie Kong et al.

Summary: This paper proposes a coupled hydro-grain-based discrete element model to explore fluid-driven micro-cracking of crystalline rock. Laboratory-scale fracturing cases over granite are simulated, revealing unique behaviors such as non-symmetrical propagation, zipper mode initiation, and generations of cracks. The cracking mode is dominated by tension failure, with variations in crack orientation and aperture influenced by in-situ stresses.
