The world's modernistic energy mix necessitates a clean and low carbon energy fuel. In this regard, the hydrocarbon sector is recognizing the ultimate potential of natural gas hydrates as a midterm solution for a resilient and sustainable future. Exploitation of natural gas hydrate will not only help us cut down carbon dioxide emissions but will also alter the geopolitics of energy. Like any unconventional resources, successful well completion and artificial lift installation are the prerequisites for optimizing production from gas hydrate reservoirs. Completing a gas hydrate reservoir was thought to be exorbitant and precarious but with advancement in technology and appropriate characterization of gas hydrate reservoirs, it is possible to complete and install artificial lift with no difficulty. This paper presents a holistic review of the completion design procedures and artificial lift techniques available for gas hydrate reservoirs focusing on the downhole equipment's and the method by which the well will be brought into production. It also highlights the completion designs, which could be followed in gas hydrate reservoirs worldwide. Furthermore, this article draws attention to the liquid loading problems in gas hydrate wells and discusses its effects on production rate, gas velocity, and liquid hold up. Compatibility of different artificial lift systems for various types of gas hydrate reservoirs has also been discussed. Finally, it also proposes a unique well completion design for controlled production along with efficient handling of sand and dissociated water. This article will help the reader to set the scene for future research activities on well completion design and artificial lift selection techniques for gas hydrate reservoirs.
