Interpretaton in the Workstation
Environment
CRAVEN, MIKE E., and EVELYN A. MEDVIN
As technology has advanced, geoscientists have turned to computer
interpretation systems, often generically referred to as workstations, to meet
the demands of ever increasing data sets. This enables the geoscientist to
integrate much of the data including seismic, well logs, formation tops, etc.
into one place in a "paperless office."
The normal practice for borehole seismic is to provide an interpreter black
and white paper copies that were useful in the old days of hand interpretation.
This is no longer practical when all other data types are being interpreted on
the workstations in living color. A more useful interpretation tool can be
provided to the interpreter if the VSP data is delivered in digital form and
integrated with the surface seismic data on the workstation.
In addition, borehole seismic surveys, such as offset VSPs or walkaway VSPs,
that are run for stand-alone interpretations tend to be fairly complicated. The
interpretation of these may be improved by integrating local well or nearby
seismic control. Seismic interpretation workstations can bring very powerful
tools to the aid of the interpreter and at the same time overcome some of the
inherent drawbacks of working on black and white paper sections. Several
examples of utilizing VSP data
within the workstation will be presented.
