DeWitt and Gonzales County Eagle Ford Shale Oil Window Big Picture

The big picture is being revealed so clearly in DeWitt and Gonzales Counties that a blind person can see.how the operators are playing out their hand..  Drilling activity, pipeline, and processing infrastructure build out is concentrating along the thick part of the Eagle Ford Shale acreage that runs along both sides of the DeWitt/Gonzales County line. Due to the highly commercial and better economics of this area, it appears that all the operators are collaborating in the early development of the Eagle Ford in this super prime location. Most of the acreage along the trend in DeWitt and Gonzales Counties is 250' to 300' thick, allowing for a more thorough matrix to be completed as a result of upper and lower horizontal wells. Where the shale is thick enough to drill two or more horizontals in layer, it effectively has a multiplier effect on the Estimated Ultimate Recovery of WTI crude oil from those wells. The maps and graphics presented below are from the operators investor presentations and the RRC.

The thickest part of the shale is concentrated along the DeWitt and Gonzales County line.

The green line from Cheapside is near the DeWitt and Gonzales County line and is the existing pipeline infrastructure and route of the new Enterprise trunk line.

The purple zone hugging the DeWitt and Gonzales Co. line is by far the most productive volatile oil window holding WTI crude oil.
