The Eagle Ford  Shale is a hydrocarbon producing formation of significant importance due to its  capability of producing both gas and more oil than other traditional shale  plays.  It contains a much higher  carbonate shale percentage, upwards to 70% in south Texas, and becomes  shallower and the shale content increases as it moves to the northwest.  The high percentage of carbonate makes it  more brittle and “fracable”.  The shale  play trends across Texas from the Mexican border up into East Texas, roughly 50  miles wide and 400 miles long with an average thickness of 250 feet.  It is Cretaceous in age resting between the  Austin Chalk and the Buda Lime at a depth of approximately 4,000 to 12,000  feet.  It is the source rock for the  Austin Chalk and the giant East Texas Field.   The name has often been misspelled as “Eagleford”.

There were 2,418 producing gas well on schedule in 2013; 875 producing gas well on schedule in 2012; 550 producing gas wells in 2011; 158 producing gas wells in 2010; and 67 producing gas wells in 2009.



History of the Eagle Ford

It is named for  the town of Eagle Ford, Texas where it can be seen on the surface as clay  soil.  Eagle Ford, Texas is approximately  6 miles west of Dallas, Texas. An  outcrop of the Eagle Ford Shale can be seen in the Dallas-Fort Worth  Metroplex.

EagleFordShale-CountiesPetrohawk drilled  the first of the Eagle Ford wells in 2008, discovering in the process the  Hawkville (Eagle Ford) Field in La Salle County (District 1).   The discovery well flowed at a rate of 7.6  million cubic feet of gas per day from a 3,200-foot lateral (first perforation  11,141 feet total vertical depth) with 10 frac stages.  Originally, there were 30 plus fields, however, due to field consolidations, the number of fields has been reduced to currently 22 active fields (with 17 inactive) located within the Railroad  Commission Districts 1 thru 5 and the fields cover 26 counties.  The wells in the  deeper part of the play deliver a dry gas, but moving northeastward out of  District 1 and updip, the wells produce more liquids.  One of the fields discovered in District 2 is actually an oil  field (Eagleville (Eagle Ford)).    The major operators joining Petrohawk in drilling the Eagle Ford Shale Play are Anadarko, Apache, Atlas, EOG, Lewis  Petro, Geo Southern, Pioneer, SM Energy and XTO to name just a few.
