|The Woodford Shale Natural Gas Field (Oklahoma Shale) play is mostly in the Arkoma Basin of southeast Oklahoma, but some drilling has extended the play west into the Anadarko Basin and south into the Ardmore Basin. To many oil and gas companies, the Woodford Shale field holds a promising source of N...
|Arkansas side of the Arkoma Basin - United States
|The Fayetteville Shale play stretches across Arkansas from approximately Fort Smith east to beyond Little Rock, Arkansas. It is approximately 50 miles wide from north to south. Geologists describe the Fayetteville Shale formation as tight, which means it requires fracturing to produce economic quant...

|The Collingwood Formation is the latest emerging Oil & Natural Gas field in the form of shale that companies are flocking to. Things started to heat up in 2008 when Encana began buying up mineral rights acreage.
|Tuscaloosa Marine shale
|Louisiana and Mississippi - United States
|The Tuscaloosa Marine shale is almost the same geological age as the Eagle Ford shale of south Texas; it's just slightly younger. It stretches all across central Louisiana over into the Florida parishes, on into Mississippi. Downdip to the south, gas production has been found in Tuscaloosa sands. It...
|Upper Devonian age in the Michigan Basin, in the US state of Michigan, and extending into Ohio and Indiana. - United States
|Antrim shale is brownish-black shale that overlies the Traverse Formation. The formation was previously known as the St. Cleric Shale in Michigan, and the Genessee Shale in Indiana. The formation is called the Kettle Point Formation in Ontario, and is the stratigraphic equivalent of the New Albany S...

|In the past, the Lewis shale, which lies between the Mesaverde and Pictured Cliffs formations, was completed in only the few wells where large Lewis flow rates were encountered while air-drilling for deeper targets. However, the Lewis shale lies behind pipe in thousands of existing wells across the ...
