Abstract: Geologic Interpretation
of 
3-D
Seismic Data
3-D Seismic DataBy
Recent developments in both marine and land End_of_Record - Last_Page 3---------------data
collection make possible 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.
