Eagleford Shale Maps

Below are several maps of the Eagle Ford shale.

The name of the oil and gas play is frequently misspelled as “Eagleford”. The correct spelling is what is seen on this website.  (If you see it spelled incorrectly here that is for purposes of search engine location.) The Eagle Ford shale takes it’s name from the small town of Eagle Ford Texas, where it outcrops in North Texas near Dallas.

The following map is from Ross Smith Energy Group . They do not sell maps to the public.  It appears here with their permission. Please do not contact me requesting clearer copies. This is the only one.  This Eagle Ford shale map shows the trend from Mexico (where it obviously continues across the border as well) to East Texas and beyond into Southwest Louisiana. It shows the low pressure, oily section in the northern region, the condensate section in the middle and the dry gas section at the lower half. Although it is difficult to read the gray areas are Austin Chalk producing areas. Wherever you find Austin Chalk production you are likely to find Eagle Ford oil as well.

Here is a map from EOG showing the oil, gas and condensate zones of the Eagle Ford Shale. You can click on the map for full size.

The following Eagle Ford shale map from the Texas Railroad Commission shows counties where wells have been drilled as of January, 2010. Note: Petrohawk Energy has identified and is developing a new oil play in Zavala county, the Red Hawk field, which is not indicated on this map. The map below is already out of date.
