What is the Woodford Shale Formation? The
Woodford Shale Natural Gas Field ( Oklahoma Shale ) is located in Southeastern Oklahoma. To many oil and gas
companies, the Woodford Shale field holds a promising source of Natural Gas. This Natural Gas is trapped in the shale
rock thousands of feet below the ground. Companies first drill vertical wells, and then drill horizontally with fracturing
techniques which involves fracturing the shale rock deposits with high pressured water. This then releases
the trapped gas. The Woodford Shale play is the result of what has happened in the Barnett Shale find for the past 20 years. Companies have gained a vast amount of their experience drilling wells in Barnett
and can use this experience along with new technologies when they drill in the Woodford Shale Gas Field.
1,500 wells have already been drilled with many more to come. The sweet spots located in the Woodford Shale are McIntosh
County to Hughes, Coal, Pittsburg and Atoka counties. Companies are leasing land in order to explore natural gas. In addition, these landholders often get up to 15% royalties on the Natural Gas found in the Woodford Shale. Fresh news in 2009, Marathon
Oil has announced they are drilling in Canadian County, OK.
Back to Horizontal Drilling. Many years ago companies
wouldn't be drilling this Woodford shale because of old technology's and the price of natural gas was low. Now it makes
economic sense. Although Horizontal wells at Woodford Shale cost alot more then vertical wells, soaring natural gas
prices have made these shale plays a gold mine. Its a huge frenzy similar to the gold rush. People are becoming
millionaires just for leasing their land to natural gas companies!
Geologists have know about woodford shale
for a long time but companies have only started exploring it ten years ago. Drilling only started several years ago.
This has boosted the average salary of the citizens from 26,000 to near 35,000-40,000 per year in McAlester. Some say
if you drive through Atoka, Coalgate, and McAlester, they are totally transformed. Great wealth is being created every
While Devon Energy drilled the first well back in 2005, many companies have taken over the Woodford Shale
in hopes to strike in big. Estimates are coming in that the Woodford Shale holds around 4 trillion cubic feet of
Natural Gas. The Woodford Shale Gas Field is not the only hot shale play out there...check out these other shale plays.

Cana-Woodford Shale - The Cana Woodford Shale is located
in Western Oklahoma. This area has become a rather nice oil play with many companies below striking oil in their acreage.
While the Cana Woodford Shale is mostly liquids rich in oil, natural gas is found there as well. In Eastern Oklahoma
we have the Woodford Shale, in Western Oklahoma we have the Cana-Woodford. More to come on the Cana Woodford Shale very
