How Deep Is the Eagle Ford?

The Biggest Wells Are Found at Depths Between 8,000 and 12,000 feet

The Eagle Ford has been drilled at depths that range from a few thousand to 14,000+ ft in South Texas.

How Deep is the Eagle Ford Formation Found?

The fairway of the play is found at approximate depths of 8,000-12,000 ft below the surface.

Oil gets heavier and harder to produce in the more shallow portions of the play and dry gas is found in deeper portions of the play. It’s the sweet spot between the heavy oil and dry gas where operators get high volumes of natural gas and condensate or oil wells.

  1. Is it true that comdensate wells produce more oil (liquid gas) than black oil wells?

    • R.T. Dukes R.T. Dukes says:

      I’m not sure I understand the question. Oil and condensate are different liquids hydrocarbons and are not liquid gas…….

  2. Good basic information. A follow-up could be: How thick is the Eagle Ford shale in the most productive areas. Also does the EOG Burrows #5 well still hold the record for most initial production and how’s its current production?

  3. J. Michal says:

    What is the “Western Gulf Basin” as shown on the Eagle Ford Shale map above?

    • R.T. Dukes R.T. Dukes says:

      The Gulf Coast Basin is a sedimentary basin that runs through South Texas and South Louisiana. The portion that is shown is just the Western portion of the entire basin.


    • J. Michal says:

      Thanks, R.T. I’m not very knowledgeable about all of this…what is a “Basin”, is that an oil play? I have property in Nueces County, Texas which looks like it is in the Gulf Coast Basin and was wondering if I should get excited that the Basin could develop into something good one day.

    • R.T. Dukes R.T. Dukes says:

      A basin is an area where sediments have settled and if organic matter was deposited there are potential for oil and gas. I suggest heading over to You’ll find other landowners who might have questions and answers specific to your area.
