not4;  This is not the case in my understanding as both reservoirs were expected a priori to be 'tight'.  So unfortunately it proved.  The Eocene is being analysed for the most efficient stimulation scheme and IMO will produce eventually.  The Cretaceous needs 3D seismic for better identification of fractured zones/areas to allow limited production.  There is no possibility of selling the acreage on a depth-related basis.  The Oligocene is the target reservoir through 2013.
