© 2021 Elsevier B.V.Gas hydrate deposits are generally found in the shallow deepwater regions and permafrost regions. The presence of water, methane, and thermodynamic conditions (low temperature and high pressure) is critical for gas hydrate accumulation. Disturbing thermodynamic conditions such as depressurizing and thermal treatment are the primary processes for gas hydrate dissociation. In this study, we investigate the stability of a shallow depth gas hydrate layer in the conditions of conventional gas production from a newly discovered deep gas field, Sakarya gas field, Western Black Sea. The study focuses on thermal conduction generated by conventional gas production across the wellbore profile along the gas hydrate section. The study includes wellbore simulations using the academic version of PIPESIM to obtain temperature and pressure profiles across the wellbore and numerical simulations for thermal transition for various cases in the hydrate zone using TOUGH + HYDRATE v.1.5 (T + H). The temperature elevation in the hydrate zone was found to change between 19 K and 25 K. The critical temperature elevation for hydrate dissociation and hydrate dissociation front were determined using the simulations, which might cause wellbore stability problems in the long term. We increase the impact of the study by suggesting appropriate solutions to minimize the adverse effects of production from the hot and deep conventional gas on gas hydrate stability found at shallower depths.
