"There is some near-surface gas hydrate, " she said Wednesday.
Occurrences of flammable tap water, if not the result of existing gas transport pipelines, can be explained by totally unrelated gas leaks that occasionally occur around coal beds, which are far closer to the surface than natural gas deposits.

The gel purportedly turns to vapor underground, then returns to the surface with the gas.
The electronic nose is an array of nano-scale gas sensors--the maximized surface area of the nano-particles allows the most gas to pass over them--along with pattern recognition technology that can create a digital fingerprint (or noseprint, as the case may be) of specific smells.
The process involves drilling a bore hole and using explosives or water to force gas to the surface.
BBC: Keynsham residents against natural gas extraction plans
In terms of containment right now, the top cap is drawing oil and gas to the surface to -- from the LMR -- the lower marine riser cap to the Enterprise.
WHITEHOUSE: Vice President Biden on Congressman Barton��s Apology to BP
The team found that most of the methane is being dissolved into the seawater and did not detect evidence of the gas breaking the surface of the ocean and getting into the atmosphere.
In the early days of oil and gas exploration, geologists would largely rely upon topology at the surface of the earth to interpret the location of oil and gas accumulations in the subsurface.
FORBES: How The Internet Of Things Will Change Almost Everything
In the study released Wednesday, researchers suggest extracting the natural gas hydrates with "depressurization" -- a method that involves changing the ice into gas and water at the surface.
On reaching the shale, the mixture of water and fracking fluid bursts open the rock and the sand keeps the fractures open, allowing the gas to flow to the surface.
Those fissures and crevices that have trapped natural gas below the Earth's surface are also capable of trapping helium, although typically in small amounts.
Defusing local opposition to "fracking" to extract gas from rocks deep below the surface is an issue many of the more tactically-adroit MPs are increasingly concerned about.
Designer Yu-ri Lee's "Tripod Burner" is little more than a three-legged gas stove that supports the cooking surface of your choice, but because of its unique shape, makes the perfect companion for a small tailgating party or romantic picnic in the woods.

The natural gas would have leaked naturally to the surface over the course of millions of years.
These are clouds of superheated gas rising above the Sun's surface, each of them larger than the Earth.
During a short cycle the solar wind (a breeze of electrically charged gas blowing off the sun's surface) is stronger than normal.
These have been key to the IPCC's conclusions that the planet's surface is warming and that humanity's greenhouse gas emissions are very likely to be responsible.
The Lipsky home in Parker County, Texas sits atop an area in the vicinity of horizontal fracking lines from two gas wells about a mile below the surface.

For more than six decades, gas companies have been using advanced technologies to hydraulically fracture and safely procure natural gas from up to two miles beneath the surface of the earth.
FORBES: Regulatory Grinches Threaten Obama's Natural Gas Christmas Wish
Since the inner part of the accretion disc orbits faster than once a second, as the hot gas ploughs into the neutron star's surface, it torques the star up to ever higher speeds.
Hydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).
This allowed natural gas to migrate up the hole and explode at the surface.
During the spill, half of the oil and most of the gas from the drilling rig never made it to the surface.
Until recently, oil and gas produced from deep-water fields have been brought to the surface and transported to onshore processing facilities.

The unit also found what it said were a number of surface-to-surface and surface-to-air missiles about 50 yards away, and about 150 gas masks of a higher quality than others left behind by retreating Iraqi troops.
Lufkin, based in Lufkin, Texas, makes pumping equipment that helps drillers extract more oil out of older fields or ones that need to be pumped because the oil and gas underground is not under enough pressure to be forced to the surface naturally.
In Pennsylvania, rules for gas sharing can in some instances change based on depths drilled below the surface.
First, what is essentially a conventional oil and gas well is drilled vertically, typically to several thousand feet or more below the surface.
The Texas Railroad Commission, using chemical fingerprinting, maintains that the EPA is wrong and that the gas seeped into the well from a shallow formation a few hundred feet beneath the surface, much closer to the water wells.
