Of course, the fly in the natural gas ointment is fracking, the hydraulic fracturing of underground rock to extract more gas and oil.
In Burlington, ConocoPhillips is buying a firm that gets some of its gas from unusual sources, such as pockets trapped in underground rock formations.
The energy firm said it would continue to store waste on site until a deep geological disposal facility was made available - similar to the storages created in underground rock caverns in Finland.
The EPA has subpoenaed Halliburton for the secret formula for the liquid chemical cocktail it pumps into underground rock structures so natural gas can be accessed through a process known as hydraulic fracturing or fracking.
Neither the best technology, nor hard-working ants, can map very far underground, and rock formations differ.

In "None Shall Pass, " underground rapper Aesop Rock comes off as a hip-hop fortuneteller, announcing what will happen in a distinctly combative way.
Unlike the normal gas extraction, chemically treated water is forced upon the rock underground to fracture it releasing the gas in the process.
But for shale gas, once the drill reaches the shale rock underground, the drill bit is turned horizontally to bore a well that stretches through the natural gas producing shale.
However, the shale rock containing natural gas is separated from underground water aquifers by impermeable layers of rock that do not allow any hydraulic fracturing fluids to migrate into underground water aquifers.

Fracking uses high-pressure liquid pumped deep underground to fracture shale rock and release gas.
BBC: Fracking firm Cuadrilla plans new well at St Annes site
The snarling Silvio from The Sopranosunleashes deliciously dirty rock at Underground Garage, channel 25 on the Sirius dial.
At the same time Yury Boiko, the Ukrainian energy minister, has high hopes that shale gas -- formed deep underground within large shale rock formations -- could also be a major alternative source of power in the decades to come.
Most of those chemicals are designed to stay underground, where they react with the rock and help the oil and gas flow.
FORBES: Shale Gas Frackers Get Excited About ... A New Sponge?
Advances in drilling technologies in the last decade have enabled energy companies to tap huge supplies of gas locked up in shale thin layers of rock a mile or more underground that reach for miles across the landscape.
FORBES: Kinder Morgan To Buy El Paso In $21B Wager On Natural Gas
Fracking involves drilling horizontally into the rock, forcing sand and water underground to cause tiny fractures that release gas from the shale.
BBC: NI shale gas deposits 'could be worth ?80bn' says report
To be a successful burial site, a body of rock needs to be more than 1km underground.
Cold ocean water leaks through the rock, hits the red-hot underground lava and bubbles up to the surface.
The underground storage areas are created by removing salt in the rock strata with equipment similar to high pressure water jets.
Instead of looking for underground hot water deposits, they drill and fracture relatively warm rock.
Fracking uses high-pressure mixtures of water, sand or gravel and chemicals to crack rock formations and release oil and natural gas deep underground.
The assertion is that hydraulic fracturing fluids, which are injected at high speed and high pressure to create cracks in the shale rock that traps natural gas, will seep into underground water aquifers.
FORBES: The Sierra Club Fails An Environmental Consistency Test
Gerry Gibson and Philip Sheldon were buried by a rock fall while working 2, 600ft (800m) underground at Kellingley Colliery in September 2011.
BBC: Gerry Gibson pit death inquest: Miners' rescue attempts
Drillers have learned to drill horizontally into long, thin seams of shale and other rock that holds oil, instead of searching for rare underground pools of hydrocarbons that have accumulated over millions of years.
