... Abstract Deepwater natural gas hydrates have attracted widespread attention as a clean energy resource, but their decomposition process will significantly change the physical and mechanical properties of the formation, posing a threat to the stability of the casing during drilling. Deepwater...

... slopes affect slope stability. The main methods for evaluating slope stability are the limit-equilibrium method ( Kang et al. 2013 ), the numerical analysis method ( Huang 2020 ), and the monitoring and warning method ( Chen et al. 2018 ). Despite the abundant research findings of these traditional...

... reduces the shear modulus of sediments, causing deformation and decreased permeability in the decomposition area. During three years of depressurization mining, the stability coefficient of hydrate-bearing slopes decreased from 1.66 to 1.41, and the maximum settlement increased to 0.864 meters, raising...
