paulflexes saidNow watch the greedy fuckers start working on technology that'll induce earthquakes.
The fracking drilling technique used to tap shale oil and gas is unlikely to trigger earthquakes, but underground injection of waste water from drilling offers more risks for seismic activity, a new U.S. study said on Friday.
The National Research Council study, which also examined the risk of earthquakes associated with tapping geothermal energy and carbon capture and storage, found that the total balance of fluid injected or removed underground was the biggest factor in causing earthquakes related to energy development.
"Although induced seismic events associated with these energy technologies have not resulted in loss of life or significant damage in the United States, some effects have been felt by local residents and have raised concern about additional seismic activity," the council said. [...]
The council's report said fracking does not pose a high risk for seismic events, citing only one 2.3 magnitude earthquake in Blackpool, England that has been officially linked to fracking for shale gas.
Yeah, I'll take that. I'll take that. Well, first, I don't know of any fracking activities in the area where the earthquake occurred. Fracking is this process where large volumes of fluids are injected in order to fracture a rock formation that has gas in it, you know, natural gas methane, in order to enhance the recovery of that. And fracking itself, actually, does not put very much energy into the ground.
Changing the way wastewater injection wells are planned and operated can largely resolve most concerns about man-made earthquakes resulting from oil-field activity, a scientist told the U.S. Senate Energy and Natural Resources Committee on Tuesday.
"I think it is clear, with proper planning, monitoring and response, the occurrence of small to moderate earthquakes associated with waste injection can be reduced and the risk associated with these events effectively managed," Mark Zoback, professor of geology at Stanford University, told the committee in Washington.
Rhi_Bran saidMost people who are scared shitless about mining today are people who were alive back in the 50's and 60's when the mining industry had almost 0 environmental regulation and did what they pleased.
Nowadays, the industry isn't like that, though there is lasting animosity towards it because of their past mistakes. Mining tanked for decades up until the late 1990's and early 2000's, when all the old firms started to put all their plans for remediation into effect. Now, it's unheard of for a mining company to not have a huge team of environmental specialists to do research in conjunction with new ventures. It takes years and years of consulting, planning, and research to actually start up a mine. Usually at least a decade.
PolyMet up here in Minnesota has been doing loads of environmental work and revising for their North Met mine since for years since everyone is up in arms about sulfate runoff. Which, granted, is a legitimate concern, but it can be controlled, mitigated, and neutralized.
Some people are just convinced that doing anything underground will inevitably destroy the earth. Mining companies are just as concerned about the environment as you are.
