What is gas?
Natural gas is a made up of a mixture of hydrocarbons. The main hydrocarbon in natural gas is methane, but there are also small amounts of ethane, propane and butane.

Natural gas originates from organic matter
like plants and tiny sea creatures that lived millions of years ago. As
the organic matter decayed it was covered with layers of silt and clay
which over time turned into rock.

Shale Gas
The magnitude of the natural gas resource
recoverable from domestic fractured shales has only been recognized within the
past decade, as a combination of drilling and well completion technology
advancements have made it possible to produce gas from shales at economic
rates. NETL research efforts are focused on further refining these
technologies, on characterizing the geology of emerging shale plays, and on
accelerating the development of technologies that can reduce the environmental
impacts of shale play development.
Environmental
It is critical that development of the Nation’s
natural gas resources take place in a manner that minimizes environmental
impacts. NETL research is focused on quantifying the risk of impacts to water,
air, and surface ecosystems, and in developing new technologies for reducing
these risks. Particular emphasis is placed on water management during shale gas
development, including enhancement of water treatment technologies
Other Natural Gas Resources
There are also significant volumes of natural
gas to be produced from tight (low permeability) sandstone reservoirs and coal
seams, two other so-called “unconventional” reservoir rocks. NETL is funding
research to better understand the underlying physics of natural gas production
from these rocks, and the relationship between well completion practices and
productivity. The objective is to find ways to maximize recovery of natural gas
from rocks which just a few decades ago were considered unproductive
