Gas hydrate is considered as a new promising energy resource, and it is extensively
distributed in offshore sediments and permafrost region. Two important factors affecting the …

In nature, permafrost regions and deep ocean sediments contain a large amount of gas
hydrate. As a basic property of the sediments, the particle size of the porous media is a …

A clear understanding of methane (CH 4) hydrate pore habits and gas seepage behaviors in
hydrate bearing sediments is critical for the exploitation of natural gas hydrate (NGH) …

In this study, we compare the changes in CO 2 saturation and pressure drop for two modes
of injections:(i) a displacement of brine by supercritical CO 2 injection (1-to-1 displacement) …

The determination of relative permeability of CO2/brine fluids under reservoir condition is
critical for the design of CO2 injection strategy and prediction of CO2 behavior underground …

As a porous medium with rich pore structure, activated carbon (AC) was once considered
the best carrier for hydrate storage and transportation. However, the harsh conditions of the …

Naturally fractured reservoirs are abundant in the earth's crust and host a substantial
percentage of oil reserves globally. The main mechanism of oil recovery during …

抄録 To better understand trapping mechanisms of CO 2 in reservoir, we try to elucidate the
effect of thin and low-porosity lamina in porous Tako sandstone on CO 2 flow by …

本研究では, CO2 地中貯留技術に資するために難透過性岩石の超臨界 CO2
の透過・貯留メカニズムの把握, また, その特性の定量的評価を目的とし, 貯留層原位置の圧力 …
