A novel mathematical method for evaluating the wellbore deformation of a diagenetic natural gas hydrate reservoir considering the effect of natural gas hydrate decomposition

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 deleterious for wellbore stability as this process can le...
