The main climate implication of the melting and breakdown of permafrost is that carbon that was trapped in the ,frozen, ground will be released and then converted to CO 2 and CH 4, leading to more warming. Sea-floor methane hydrates are stable because the deep ocean water is cold.

Fracking is a popular term referring to hydraulic ,fracturing, when it is used to extract hydrocarbons. We distinguish between low-volume traditional fracking and the high-volume modern fracking used to recover large volumes of hydrocarbons from shales. Shales are …

Discharging coal fines with water or water-based ,fracturing fluid, from the proppant pack can be difficult because of the adsorption and hydrophobicity of coal fines. Thus, coal fines are likely to aggregate and be retained in the proppant pack, thereby resulting in pore …

In the course of a hydraulic fracturing operation, a base fluid must first be low-friction to convey the fracturing pressure underground, and then the fluid must become viscous to effectively transport proppants into the formation, and subsequently, the fluid must become nonviscous again to facilitate flow back to the surface.

On the other hand, a metal pipe shrinks when ,frozen,. In a pipe, ice forms first on the inside wall of the pipe and grows radially inward until there is a solid plug of ice blocking the pipe. Until that situation occurs, the expansion of the freezing water in the pipe merely pushes water ,back, into the water main.

Anhydrite (2.3–2.6 g) is predicted to precipitate from each ,fluid, but then redissolves ,back, into the ,fluid, as the titration of seawater into hydrothermal ,fluid, continues and temperature decreases. Similarly, pyrite (29–43 mg) and amorphous silica (20–64 mg) precipitate from Bastille and Dante fluids, but then redissolve ,back, into the mixed ,fluid, as the seawater titration continues.
