Summary

Using carbonate examples, some methods for determining facies boundaries at the interwell scale, and therefore potentially constraining geostatistical correlation, are presented. Modern environments and outcrops are valuable as reservoir analogs. Crosswell seismic profiles and horizontal well data are direct detection methods within a reservoir. Although all of the methods have shortcomings, they should be utilized to the fullest extent possible, in conjunction with geostatistical approaches, during a reservoir characterization effort.
