This talk discusses the possibility that the Austin Chalk and Eagle Ford Shale form a single hydrocarbon system.  The potential source, generation, migration, storage, and production mechanisms of both formations will be analyzed from a geologic perspective.  The implications of this theory for exploiting the Eagle Ford Shale will also be discussed.  From a production standpoint, this presentation will compare the production trends of horizontal wells in the Eagle Ford Shale and Austin Chalk formations, analyzing each in detail to determine if there are any similarities in initial production rates and decline trends.  Furthermore, some production analyses will also be undertaken to point out some behavioral trends of Eagle Ford horizontal well production profiles.

 

This talk investigates the areal extent of production from the Eagle Ford Shale and Austin Chalk formations and discusses their interdependencies.  In addition, geological and petrophysical attributes are evaluated to understand this phenomenon.  Lastly, this paper describes the key mechanism(s) for oil/condensate flow in these oil-producing reservoirs and how to best exploit these unconventional formations.  Some discussion will also be centered around how to take lessons learned and apply them elsewhere in the world.
