From offshore oil to previously inaccessible gas deep in the earth, the federal domain is poised for an energy renaissance.
Oil and gas this deep in the earth is often as hot as 450 degrees and at pressures 2, 000 times atmospheric.
At that depth, a key piece of equipment is the blowout preventer, which weighs up to 300 tons and caps the well, holding back ultrapressurized oil deep in the Earth.

Eyjafjallajokull, in Iceland, which erupted in April, stopping commercial flights over the Atlantic and Europe for a week, is at a junction where the plates are growing and moving apart, as magma wells up from deep in the Earth.

According to a new computer model, liquid methane in contact with a partially hydrogen-terminated diamond surface at extremely high pressures and temperatures spontaneously forms longer hydrocarbons, and hence the material of crude oil could be formed deep in the earth.
These unsung passages function as the smaller veins feeding into the main artery of the Grand Canyon, the up-to-18-mile-wide, mile-deep gash in the earth through which 227 miles of the Colorado River snakes.
In fact, some experts believe petroleum is not a fossil fuel at all but some sort of gloppy syrup that is produced deep down in the earth under extremely hot conditions and is pushed up by intense pressure.
Although it is now widely accepted that the site was a burial ground at one point, based on human DNA found in the earth deposits deep underground, the length of time for which this was the case is not certain.
The other approach is less risky, and involves removing carbon directly from the atmosphere and burying it in vast ocean storage beds or deep inside the earth.
These organisms, which have fundamentally different metabolisms to normal microbes, are found in hydrothermal vents on the deep-ocean floor and in rocks and springs hundreds of metres below the surface of the Earth.

The geothermal system heats and cools using piping that goes deep within the earth, where temperatures are warmer than outside air in the winter and cooler in the summer.
So being able to study reconnection up close could lead to a better understanding of the behaviour of plasma on earth, on the sun, and in deep space not to mention improved space-weather forecasts.
Chemicals found in fossils deep down in the samples span the ages and are good indicators of historic temperatures on Earth, Marcott said.
Scientists have found creatures thriving in places that would poison or cook most life on earth--deep inside rock, under the ocean or in hot springs, places that are extremely salty, or acidic, or bathed in radiation or heavy metals.
"The important thing to consider is that the Earth has a very deep gravity well so anything you can make in situ on the Moon will save an awful lot of energy and therefore money, " he said.
Since Russia and the U.S. signed a partial test-ban treaty in 1963, their blasts have been deep below the earth's surface.
Jon Ramer: Embedded in my history and deep in my bones is the idea that our purpose here on earth is to help mend and heal the world.
Once we spent the holidays high up in the Swiss Alps, where my body stiffened at the sight of deep hollow chasms emptied out of the rocky earth.
The most recent spikes in the Earth's temperature are no different, long term, than the peaks one finds beside deep valleys on the Earth's surface.
During gasification, the carbon dioxide generated from the coal or other feedstock, like biofuels, is captured and then used to inject deep into the earth as part of oil recovery or otherwise sequestered in a geologic formation.

It comes from a garden wholesaler, which provides the high quality soil, taken deep beneath the earth's surface -- 10 meters down, in fact.
"The radiation environment in deep space is several hundred times what it is on Earth, and that's even inside a shielded spacecraft, " Zeitlin said.
