A seismic analysis
using Stratimagic was performed
on Sonat's Beargrass 3-D seismic survey located in
the prolific reef trend of East Texas. Fifteen seismic anomalies
had been identified and drilled during 1996-97. Production
characteristics of these individual reefs varied widely indicating
pervasive reservoir heterogeneity. Conventional seismic
attribute
analysis
, although useful in delineating the distribution of reefal
buildups was unsuccessful as a tool for characterizing differences
in reservoir performance. Stratimagic facies maps were used to
classify the trace shape of the reef interval into 15 different
categories. Modifying the color palette to highlight reefs with a
trace shape similar to the highly successful Fountain #1 anomaly
gave a good correlation between high-rate and low-rate
anomalies. This
analysis
quickly and accurately begins to characterize
the differences between individual stratigraphic reservoir
bodies that can be used for both future field development and as
a tool for trend exploration before drilling.
