Research on Wellbore Stability in Deepwater Hydrate-Bearing Formations during Drilling

open access: yesEnergies
Marine gas hydrate formations are characterized by considerable water depth, shallow subsea burial, loose strata, and low formation temperatures. Drilling in such formations is highly susceptible to hydrate dissociation, leading to gas invasion, wellbore
