- 摘要：
- The present invention is directed to using depressurization methods to create mobile fluid zones for producing fluids from a Class 3 hydrate reservoirs through a well. Aspects of the present invention include a two stage method wherein the first stage includes producing fluid from a hydrate interval within the Class 3 hydrate reservoir through a well at a constant pressure and forming an interface, and the second stage includes producing fluid through the interface at a constant mass rate and heating the well.
