Paper Number: ARMA-2024-0094
... perpendicular to the direction of the minimum horizontal principal stress (σ h ). The HF near the well usually crosses the gravel, while the HF tends to bypass the gravel or even be inhibited by the gravel far away from the well. The waterfall diagram of the optic fiber strain can monitor the HF propagation...

Paper Number: ARMA-2024-0867
.... Typically, shotcrete cores are obtained along the direction of application, leading to an oversight of its strength perpendicular to this direction. Consequently, the true bearing strength of shotcrete is neglected, despite higher stresses acting normal to the application direction. While the anisotropic...

... of the laminated rocks. The material exhibits higher effective stiffness when loaded parallel to the laminations, while stiffness is lower perpendicular to the laminations. The evolution of cracks proves intricate, reflecting a delicate interplay between material elastic constants, strength properties, and loading...

Organic shales present in the Bakken and Three Forks formation, and other formations all over the world, are characterized by velocity anisotropy with lower velocity in the direction perpendicular to the lamination. Characterizing anisotropy is critical not only from the seismic...

... at directions parallel and perpendicular to their bedding plane. Shale samples were tested through instrumented nanoindentation using grid arrangements with maximum loads of 4,000 μN and 10,000 μN. The results suggest that the mechanical properties of the tested shales showed an inverse relationship...
