Thermodynamics analysis and temperature response mechanism during methane hydrate production by depressurization

Shuang Dong et al.

Summary: This study investigated the temperature response mechanism during methane hydrate production by depressurization. It was found that the temperature decreases with the progress of depressurization and accelerates as the hydrates start to dissociate. The pressure and temperature trajectories are parallel to the hydrate phase equilibrium line at the highest dissociation rate, forming a stationary state of hydrate dissociation.

Effects of underlying gas on formation and gas production of methane hydrate in muddy low-permeability cores

Jie Zhao et al.

Summary: This paper analyzes the effects of underlying gas on the formation of hydrate and methane production behaviors, highlighting that the underlying gas pressure is the decisive factor for hydrate saturation. The production of underlying gas and hydrate decomposition are interdependent during depressurization.

Gas production enhancement effect of underlying gas on methane hydrates in marine sediments by depressurization

Jie Zhao et al.

Summary: The pressure of underlying gas in marine hydrate reservoirs has a positive effect on hydrate decomposition, gas production, and water production, as well as promoting the formation of gas-water flow channels. By reducing temperature drops and shortening hydrate decomposition time, the role of underlying gas in enhancing hydrate reservoir exploitation has been preliminarily demonstrated.

Production Behaviors of Water-Saturated Methane Hydrate Deposits during the Depressurization with/without Thermal Water Compensation Process

Jia-nan Zheng et al.

Summary: This study investigated the production process of water-saturated marine methane hydrate deposits through depressurization and compensation, revealing three stages of release, equilibrium, and free, and an additional compensation stage during water injection. The effective temperature increase based on the phase equilibrium temperature was confirmed to be the deciding factor of decomposition rate of hydrates in the equilibrium stage. Additionally, gas/water production of water-saturated hydrate deposits is jointly controlled by water injection and hydrate decomposition.

Ice behaviors and heat transfer characteristics during the isothermal production process of methane hydrate reservoirs by depressurization

Mingjun Yang et al.

Summary: By adjusting the reservoir temperature and production pressure, the production process of methane hydrate and the behavior of ice can be controlled, thereby affecting the dissociation rate of hydrates. Higher production pressures can prevent the formation of ice, and both the melting of ice and the dissociation of hydrates are influenced by heat supply.

Dynamic permeability and gas production characteristics of methane hydrate-bearing marine muddy cores: Experimental and modeling study

Jie Zhao et al.

Summary: The study found that effective stress has a negative impact on reservoir permeability, while hydrate saturation has a greater influence on dynamic permeability. The modified permeability model can accurately predict underlying gas pressure and the trajectory of the hydrate dissociation front.
