Unit Definitions

One of the criteria determined in a unit hearing is the unit definition from a geologically perspective.  The unit will reference a nearby well and define the vertical stratigraphic interval to be considered part of the unit.  Comparing unit definitions across the play presents some interesting takeaways.  EOG has defined the interval to cover most of the Eutaw (Base of the Austin Chalk to base of the TMS).  It's also interesting to note that EOG used the same definition well for both of their units.  If one evaluates that well and its completion history, they might conclude that EOG has plans to test the middle to upper Eutaw in addition to the TMS.  I'm confident that EOG will leave no "stone unturned".
