Summary

[edit]
Description

The Eagle Ford play has four major boundaries:

- The western border is the Rio Grande River, which forms the international border with Mexico. EIA does not have well-level production and geologic data from the Eagle Ford formation on the Mexican side of the border.

- The northern boundary is defined according to the thermal maturity—the temperature range at which oil is generated from the source rocks—of the hydrocarbons within the Eagle Ford Shale. The oil window ends and the immature area begins above a minimum subsea depth (i.e., depth below sea level) of 3,650 feet in Frio County and counties east, and above minimum depths in Maverick and Zavala counties, ranging from 650 to 2,900 feet.

- The southern boundary of the play traces the edge of the hydrocarbon-bearing part of the Eagle Ford Shale along the Sligo Reef Margin.

- The northeastern boundary roughly corresponds with where the carbonate-rich lower Eagle Ford (the primary target for drilling and completion) tapers off and transitions into silica-rich rock units of the Pepper Shale of the East Texas Basin, which, while hydrocarbon-bearing, is characterized as a different play than the Eagle Ford.
