We seldom do petrophysical analysis for its own sake – usually the
results are used as input to some other activity, like a well
completion plan, an economic analysis, or a reservoir description
for a full field simulation study. Many users of petrophysical
results do not appreciate all the data that may be helpful in
running and calibrating a petrophysical analysis. More importantly,
they often do not know what other disciplines may get from a
competent petrophysical analysis, in addition to what was initially
requested. Petrophysicists may not be aware of what those other
disciplines can do with their output.
This page is designed to give users and doers a brief overview of
what can be derived using log analysis results and what other data
might be available to help get the job done.
