Title: Strategies for gas production from hydrate accumulations under various geologic conditions

Abstract

In this paper we classify hydrate deposits in three classes according to their geologic and reservoir conditions, and discuss the corresponding production strategies. Simple depressurization appears promising in Class 1 hydrates, but its appeal decreases in Class 2 and Class 3 hydrates. The most promising production strategy in Class 2 hydrates involves combinations of depressurization and thermal stimulation, and is clearly enhanced by multi-well production-injection systems. The effectiveness of simple depressurization in Class 3 hydrates is limited, and thermal stimulation (alone or in combination with depressurization) through single well systems seems to be the strategy of choice in such deposits.
