A failure criterion fully considering the anisotropy and hydration of shale is essential for shale formation stability evaluation. Thus, a novel failure criterion for hydration shale is developed by using Jaeger’s shear failure criterion to describ

Diagenetic natural gas hydrate (DNGH) is a metastable material that is widely distributed in the frozen formations of Qinghai–Tibet Plateau in China. Drilling boreholes in such frozen formations can lead to the decomposition of DNGH, which is delet

It is well known that the effect of shale hydration causes wellbore instability due to water phase invasion of drilling fluid to lamellar shale rich formations. This is because of that the mechanical properties (compressive strength, elastic modulus,
