Effect of Shear Rate on Crack Development, Fracture Surface Morphology and Permeability Characteristics in Sandstone

Key Points

• Crack development is significantly influenced by shear rate, affecting the permeability of sandstone.
• A notable finding shows that increased shear rates result in distinct fracture surface morphologies.
• Assessment using experimental models reveals the relationship between shear rate and permeability characteristics.
• These results highlight how variations in shear rate can alter the physical properties of sandstone formations.
