Sentences with phrase «rocks at high pressure»

Then, that water broke through the crater rim (artist's concept, lower right), possibly through a weak spot previously eroded by ground water seeping through the rocks at high pressure.

Normally, the reaction happens too slowly to be useful, but injecting carbon dioxide into the rock at high pressure would speed things up considerably; the formation of magnesium carbonate could cause the rock to expand and crack, with the increased surface area spurring the reaction to continue.

Not exact matches

Hydraulic fracturing, or fracking, deploys a mix of water, sand and chemicals at high pressure to release gas or oil trapped in rocks.

Hydrofracking is the process of extracting natural gas from shale rock by blasting a mix of water and chemicals at high pressure into underground wells.

At the high temperatures and pressures found at depth, it reacts with silicate minerals in rocks to form a carbonate deposiAt the high temperatures and pressures found at depth, it reacts with silicate minerals in rocks to form a carbonate deposiat depth, it reacts with silicate minerals in rocks to form a carbonate deposit.

If the water pressure at the plate interface zone becomes as high as the pressure of the overlying rock column, the strength of the rocks at the plate interface becomes practically zero - an effect akin to aquaplaning will initiate eventually triggering an earthquake.

Green explained that at 300 - 700 kilometers depth, the pressure and temperature are so high that rocks in this deep interior of the planet can not break by the brittle processes seen on Earth's surface.

Sediments tend to become denser at high temperatures and pressures, and eventually turn into rock.

This process involves injecting a slurry of water, chemicals and sand into wells at high pressure to fracture the rock and create veins that can carry trapped gas to the well.

After the researchers analyzed the inclusions — each just 15 to 40 microns wide, or one - sixth to two - fifths of the diameter of a human hair — they found the inclusions contained the entire range of minerals one would expect of a volcanic rock called basalt that originally formed at the planet's surface and then crystallized under extreme high pressures and temperatures.

In the right locations, CO2 injected into the ground at high pressure would react with those minerals to form stable carbonate rock.

hydraulic fracturing, or fracking The cracking open of undergound rocks by introducing liquid at high pressure, especially to extract natural gas.

Millions of gallons of water mixed with sand and up to 300 tons of chemicals are then pumped into the well at high pressure to create breaks in the rock and release the gas.

CO2 at high pressure forms a liquid, then ultimately reacts with igneous rocks to form CaCO3.

The 600 - plus - page report that resulted looks at a variety of ways fracking could have an effect on local drinking water: withdrawing millions of gallons of water needed to frack a well, improperly mixing chemicals with the water at the well, injecting that fracking fluid into the ground at high pressure to fracture rock as much as two miles beneath the surface, handling the contaminated water then produced by the well and finally improperly storing or disposing of that water.

A mixture of water and chemicals sent through the drill hole at high pressures creates fractures in the rock and allows the trapped natural gas to escape to the surface.

In this process, water is pumped at high pressures to fracture underground hot rock reservoirs similar to technology used in natural gas hydraulic fracturing.

installing an EGS plant typically involves drilling a 10 - to 12 - inch - wide, three - to four - kilometer - deep hole, expanding existing fractures in the rock at the bottom of the hole by pumping down water under high pressure, and drilling a second hole into those fractures.

Hydraulic fracturing sends «huge volumes of toxic fluids» deep underground at high pressure, to fracture shale rock and release natural gas, Food & Water Watch claims.

Fracking, or Fracing as the oil and gas industry ungrammatically spells it, is short for hydraulic fracturing, and the technology is now being used extensively to extract shale gas, by pumping liquids at high pressure into the rock, creating and expanding fissures.

We believe that fracking poses a tremendous threat to agriculture, to our drinking water, and to our climate, because when you are injecting millions of gallons of water, chemicals and sand, four or five miles underground at very high pressure and breaking open the rock and releasing gas there's all sorts of contamination that can happen.
