In this paper, a model for predicting gas production from hydrate deposits by heat stimulation was developed. The model was idealized and simplified by neglecting the effects of heat convection and pressure in sediment. The result shows that the maximum amount of cumulative gas production at Shenhu is about 509 m³ per meter in three years, and the production potential is much lower than the industrial criterion for marine production. Therefore, it is concluded that hydrate dissociation rate is very low, and production cost is high and economic value is low under the current production technology. Thus it is unfeasible to produce gas from Shenhu hydrate deposits only considering the thermal conduction.
