Fluid production behavior from water-saturated hydrate-bearing sediments below the quadruple point of CH4 + H2O

Qing-Cui Wan et al.

Summary: Driven by large resource volume, extraction of CH4 from hydrate reservoirs has attracted global attention. Depressurization is considered a feasible method, but the fluid production behavior from water-saturated hydrate-bearing sediments below the quadruple point of CH4 + H2O still needs further investigation. Experiment results show that ice formation affects temperature response, but does not significantly impact gas production. Higher hydrate phase saturation improves gas production rate and final recovery ratio, indicating ultra-deep depressurization as a viable option for enhancing CH4 recovery.

Characterizing Mass-Transfer mechanism during gas hydrate formation from water droplets

Huiyong Liang et al.

Summary: The study investigated the mass-transfer characteristics of water and guest molecules in dense hydrate structures during formation from water droplets. Experimental results showed time-dependent 3D morphologies and parameters of hydrate shells, revealing a transition in the water transport schema within hydrate shells from diffusion to permeation. The effective diffusion coefficients of gas and water molecules in hydrates were quantified, providing fundamental insights for optimizing hydrate-based techniques.

Effect of well configuration, well placement and reservoir characteristics on the performance of marine gas hydrate reservoir

Neelam Choudhary et al.

Summary: Reservoir simulations are crucial for predicting long-term gas production from gas hydrate reservoirs. Various well placements and configurations were explored in this study to analyze gas production strategies for an oceanic, unconfined, class-2, gas hydrate reservoir. The effectiveness of depressurization and the necessity of warm water injection were demonstrated, with injector placement playing a critical role in gas production behavior. Additionally, the reservoir porosity and layering significantly affect gas recovery and production behavior.

Long-term numerical simulation of a joint production of gas hydrate and underlying shallow gas through dual horizontal wells in the South China Sea

Rupeng Wei et al.

Summary: Recent field tests in Japan and China have attracted worldwide attention to marine gas hydrate reservoirs. To improve economic efficiency, a new scheme is proposed to jointly produce gases from the hydrate layer and its underlying shallow gas layer. The use of dual horizontal wells can significantly increase cumulative gas yield compared to a single vertical well scenario. However, there is a potential risk of interlayer failure due to pressure differences, which can be mitigated by controlling the depressurization scheme in different layers. An analysis shows promising positive energy harvest and suggests its potential application in field tests in the South China Sea without disturbing reservoir stability.

Thermodynamics analysis and ice behavior during the depressurization process of methane hydrate reservoir

Yongchen Song et al.

Summary: This study investigates the thermodynamics characteristics during hydrate dissociation and finds that the dissociation rate is significantly influenced by the depressurization rate and gas space. During the constant pressure stage, ice formation can nearly quintuple the instantaneous rate of hydrate dissociation. These findings are of great importance for pressure control and efficiency optimization in the later period of methane hydrate exploitation.

Numerical study of gas production from fine-grained hydrate reservoirs using a multilateral horizontal well system

Peixiao Mao et al.

Summary: This study innovatively employs a multilateral horizontal well system to improve production efficiency in fine-grained hydrate reservoirs. A 3D numerical model is used to evaluate the influences of well configuration, deployment location, depressurization pressure, and reservoir properties on production. The results show that multilateral horizontal wells can enhance production efficiency in specific conditions, especially when branch number and length are increased.

Methane recovery and carbon dioxide storage from gas hydrates in fine marine sediments by using CH4/CO2 replacement

Tian Wang et al.

Summary: This study explored the characteristics of CH4/CO2 replacement in fine marine sediments, with pressure and temperature identified as the main controlling factors. The content of initial methane hydrate and water in reservoir was found to have a more significant effect on CO2 storage than CH4 recovery. The unique properties of fine marine sediments, including small grain size, clay swelling, and high proportion of bound water, inhibited gas exchange kinetics and CO2 diffusion in the replacement process.

New Approach for Determining the Reaction Rate Constant of Hydrate Formation via X-ray Computed Tomography

Huiyong Liang et al.

Summary: Gas hydrates have been studied for their potential applications in energy storage, gas separation, and carbon dioxide sequestration. The study presents a new method for determining the reaction rate constant of hydrate formation using high-resolution X-ray computed tomography measurements. The experimental results showed an increase in reaction rate constant with temperature, indicating an activation energy of 56.6 kJ/mol. This approach may have broader applications in studying kinetics of other gas hydrates.

Zhao Jiafei et al.

Summary: A lightweight structure with sufficient mechanical strength and heat transfer performance is increasingly required for thermal management issues. Porous structures, such as open-cell foam, lattice-frame, structured packed bed, and wire-woven structures, have attracted significant scientific and industrial interest due to their potential in supporting stress and fluid flow. The comprehensive comparison and evaluation between different porous structures remain largely unclear, with a need for new methods to accurately measure morphology and more research on forced convection heat transfer in high velocity regions.

Tuning the fluid production behaviour of hydrate-bearing sediments by multi-stage depressurization

Qiang Gao et al.

Summary: Natural gas hydrates are high-energy-density and clean energy source with great potential for producing methane. Multi-stage depressurization processes have been investigated for dissociating water-saturated hydrate-bearing sediments, showing that increasing the number of stages and refinements can control hydrate dissociation rate and significantly reduce cumulative fluid production in each stage. Different mechanisms, driven by heat transfer and pressure drawdown, affect the fluid production behavior, with increasing number of stages leading to improvements in minimum temperature and energy efficiency ratio.
