Seismic data processing of a 1972 vintage 2-D seismic line in the Val
Verde Basin overthrust is compared to modern reprocessed results and to
recent seismic data shot in the region. Improvements in seismic imaging
are from accurate geometry installation, detailed velocity analyses, improved
residual statics algorithms, modern coherency filters, and a broader spectral
bandwidth. Interactive seismic data processing and interpretation are achieved
through a network of Pentium Pro NT and IBM 43P RISC 6000 UNIX computer
workstations. Seismic data processing is done using an interactive version
of the Phoenix Vector seismic data processing system. Data are interpreted
using GMA 2-D seismic interpretation software. Close integration of seismic
data processing and interpretation from computer workstations and application
software allows for accurate and efficient reprocessing of seismic data
by the exploration team.
When comparing modern reprocessed 1972 vintage data to recent seismic
data, many of the interpreted structural and stratigraphic features are
the same. Results indicate that reprocessing of older vintage 2-D seismic
data could make a significant impact on exploration programs. Several new
play trends are defined by the reprocessed results.
