Exxon's concepts of sequence stratigraphy
developed from the stratigraphic interpretation
of reflection seismic
data, a technique
known as
seismic
stratigraphy. Differentiation
of chronostratigraphy from
lithostratigraphy is critical in interpreting
sequences on
seismic
data. Extensive experience
indicates that reflections follow
time lines in the rock record and that facies
variations are recorded by lateral changes
in reflection attributes. Integration of all
available well, outcrop, and literature data
in a
seismic
interpretation is essential to
reducing the risks associated with predictions
of play parameters using
seismic
stratigraphy.
Predictions based on seismic
stratigraphy
have been confirmed by drilling in frontier
and developing areas. The level of stratigraphic
detail needed from a
seismic
interpretation
varies with technical and business
objectives. The interpretation of sequence
sets may suffice to establish basin history,
but
seismic
identification of individual sequences
or system tracts may be required
to establish plays and prospects. Even with
little or no well control, the presence, distribution,
and continuity of individual reservoir
and source units can be predicted
using
seismic
stratigraphy, as illustrated by
applications in lacustrine and deep-marine
settings.
Although limited by seismic
resolution,
detailed stratigraphic interpretations of thin
intervals have significant impact in mature
areas. The geometry and
seismic
attributes
of even individual reflections provide critical
data about reservoir distribution, reservoir
continuity, and field segmentation, as
illustrated by applications in reservoir
modeling
and reservoir management.
