What is the Eagle Ford Shale formation?

The Eagle Ford Shale is a Cretaceous sediment that was traditionally known as a source rock in South and East Texas. The formation is the source rock for the Austin Chalk oil and gas formation. Producers also drilled through the play for many years targeting the Edwards Limestone formation along the Edwards Reef Trend.

Why is it called Eagle Ford Shale?

The Eagle Ford Shale is located in South Texas producing from various depths between 4,000 and 12,000 feet. It derives its name from the town of Eagle Ford TX where the shale outcrops at the surface in clay form. The Eagle Ford formation does have a dry gas, a gas condensate, and oil an oil window.

What type of rock is the Eagle Ford?

sedimentary rock
The Eagle Ford shale (Eagleford shale) (discovered in 2008) is a sedimentary rock formation from the Late Cretaceous age underlying much of South Texas which covers 3000 square miles and consists of an organic-rich marine shale that also has been found to appear in outcrops (Braithwaite, 2009; US EIA, 2011a).

Is Permian Basin a shale?

The Permian Basin is a shale basin about 250 miles wide and 300 miles long, spanning parts of west Texas and southeastern New Mexico. It includes the highly-prolific Delaware and Midland sub-basins.

What is Woodford Shale?

The Woodford shale is one of several organic rich “black” shales of late Devonian and early Mississippian age present in basins of the North American craton. The Woodford shale is widely regarded as a major source rock in the Anadarko basin.

What is shale oil and gas?

Shale oil is an unconventional oil produced from oil shale rock fragments by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock (kerogen) into synthetic oil and gas. The refined products can be used for the same purposes as those derived from crude oil.

Where is the Eagle Ford Shale?

The Eagle Ford Shale is a hydrocarbon-producing geological formation extending over 26 counties. It stretches from the Mexican border between Laredo and Eagle Pass up through counties east of Temple and Waco.

Where is the Niobrara shale located?

The Niobrara shale formation (Denver-Julesburg Basin, Colorado) is a shale rock formation located in Northeast Colorado, Northwest Kansas, Southwest Nebraska, and Southeast Wyoming. Oil and natural gas can be found deep below the earth’s surface at depths of 3000–14,000.

What oil basin is in Oklahoma?

The Anadarko Basin
The Anadarko Basin is a geologic feature covering approximately fifty thousand square miles primarily in west-central Oklahoma, but including the upper Texas Panhandle, southwestern Kansas, and southeastern Colorado.

Where is Eagle Ford Shale located?

Oil can be found in McMullen County, Texas while Natural Gas has been found in the Eagle Ford Shale located in La Salle County, TX. The Eagle Ford Shale is located directly below the Austin Chalk Formation and is estimated in some spots to be as deep as 11,300 feet.

What county is Eagle Ford Shale in?

The Eagle Ford Formation (also referred to as the Eagle Ford Shale) lays under much of South Texas and covers roughly 24 counties. The name comes from an old community called Eagle Ford where the outcrops of the Shale were first discovered.

Where is Eagle Ford Shale?

Eagle Ford. The Eagle Ford Shale is located in South Texas. It is approximately 50 miles wide and 400 miles long, running from the US-Mexico border north of Laredo , extending for a hundred miles to just north of Houston.

What is Eagle shale?

The Eagle Ford Group (also called the Eagle Ford Shale) is a sedimentary rock formation deposited during the Cenomanian and Turonian ages of the Late Cretaceous over much of the modern-day state of Texas.
