Abstract
Abstract: Geologic Interpretation
of
3-D
Seismic Data


By
Recent developments in both marine and land data
collection make possible End_of_Record - Last_Page 3---------------3-D
reflection seismic work for use
in detailing known prospects or for post-discovery field
development. Techniques have been developed for both
marine and land systems that make it both feasible and
economical to collect dense data for use in
3-D
migration and
other
3-D
related processes. Special software processes are
utilized to gather the subsurface information into a uniform,
dense, depth point grid prior to input on
3-D
migration.
Interpretation of the large volume of data is made easier
utilizing some new display techniques. "Arbitrary" slices,
including diagonal and horizontal, through the
3-D
volume of
data before and after
3-D
migration show the effectiveness
and flexibility of the
3-D
system. Since the data are migrated
3-D
, all line intersections time tie. Actual data examples
illustrate the improvements in seismic imagery made
possible with
3-D
coverage.
