Eagle Ford Shale Texas

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. Often the Eagle Ford is mistakenly spelled as “Eagleford”. The Eagle Ford is still an emerging shale play, however operators have accumulated large acreage positions and well results are promising. Unlike many other shale plays, the Eagle Ford thus far does not exhibit natural fracturing within the formation. The Eagle Ford formation does have a dry gas, a gas condensate, and oil an oil window.

Eagle Ford Shale Geology

The Eagle Ford Shale is a geological formation directly beneath the Austin Chalk formation. It is considered to be the “source rock”, or the original source of hydrocarbons that are contained in the Austin Chalk and the Edwards formation above it. The formation is being targeted for both oil and gas. It produces a liquids rich gas and condensate stream, as well as oil in certain areas of the play. The Eagle Ford Shale is found at depths between 4,000 and 12,000 feet. The shale is up to 250 feet thick in some places, generally without natural fracturing present. Much of the production occurs at the convergence of the Stuart City Reef trend and the Sligo Reef Trend.
