Abstract: Three-Dimensional Seismic
Displays as
Interpretation
Aid
R. C. Farrell
Today's seismic
interpreter must evaluate many miles of
data
displayed on many feet of paper before he can render an
interpretation
of a prospective area. Several hours could be spent just getting a "feel" for the area. What he needs--before he starts the
interpretation
--is a computer-generated three-dimensional
seismic
display. Such displays expand the amount of
data
available to the eye at one time, allowing a rapid appraisal of the structure. Detailed study still must be completed, but it need not be so difficult as it once was.
Interpretation
of fine detail is easier, too, where
seismic
attributes such as reflection strength, frequency content, or interval velocity are added in color to the 3-D display.
Once the interpreter has picked his structure he may request another 3-D display with the seismic
data
stripped from above his time picks. When displayed at a picked horizon, the 3-D display quickly isolates
interpretation
errors for subsequent correction.
A three-dimensional display of the prospect also forms a powerful tool for presentation of integrated interpretation
data
to exploration management. Prospective drill locations are presented with all relevant
data
in a compact display on a single sheet of paper.
