Drillinginfo has been on a tear lately releasing new Landtrac counties on a weekly basis it seems. After Goshen County a couple weeks ago, they just released Dimmit and Zavala. This is of great value to people such as myself who follow the Eagle Ford.
Dimmit County has been dominated by one producer thus far, Anadarko. They have over 35 Eagle Ford producers and a scaled back, dry gas Pearsall program to boot. In 2010 alone they have permitted Dimmit County 55 times.
However there are other producers in the area such as Newfield and Chesapeake. The above graphic shows the Dimmit Eagle Ford producers colored by cumulative produced gas and bubbled by maximum liquids produced per month. When you bubble the wells by liquids you can see how the trend becomes gassier when you move towards the south. Most of these wells are Anadarko and have not been online for very long. The highlighted Chesapeake Lazy A Catulla produced the highest amount of liquids per month, at 663 BOPD.
Looking at the Landtrac Grantee histogram you can see companies like CML (mostly Austin Chalk), SM Energy (St Mary), Chesapeake and other less known grantees.
Most of the Eagle Ford producers in this county are to the south. As you go north towards Zavala, Eagle Ford production gets pretty oily and may necessitate artificial lift (see Petrohawk Mustang Ranch, Red Hawk prospect).
With the depths decreasing to the north, the pressure and gas drive mechanisms aren’t there.
