Gas-water relative permeability is a key parameter in the trial production of natural gas hydrate. Measurement and evaluation of the parameter of the hydrate reservoir is essential for enhancing gas production efficiency and realizing the industrializati
It is profitable to drill to depths more than 1,000 feet for oil and gas extraction, but only recently in California has it become profitable to pump water from this depth. 从1,000英尺以下的深度开采石油和天然气是有利可图的,但只有最近在加利福尼亚,从这个深度以下抽取地下水才变得有利可图。
thesolidstate is denser than the liquid state; thus, the solid would sink to the bottom of the liquid. The fact that ice floats on water is exceedingly important in the natural world, because the ice that forms on ponds and lakes in cold areas of the world acts as an insulating barrier...
Green hydrogen produced by water splitting using renewable energies is essential to reduce greenhouse gas emissions, especially in hard-to-abate industrial sectors such as steel, cement and ammonia production. At present, water electrolysis technologies are uncompetitive with the low-cost production of ...
Here we report the discovery of water ice in the HD 181327 debris disk using the near-infrared spectrograph onboard the James Webb Space Telescope. We detected the solid-state broad absorption feature of water ice at 3 µm including a distinct Fresnel peak at 3.1 µm, which is ...
