While we easily involve the geologist and the geophysicist in our work, we tend to do it less with our petrophysicist. Many geomodelers are geologists or geophysicists by background. Maybe it leads us to spend more time on building the horizons, the faults and then facies distribution in 3D, and less on the challenges of populating the petrophysics in 3D.

It would be a mistake to not consider the complex relationship existing between the different properties (cross-plots). Our petrophysicist can help us a lot to understand these relationships. Many would be happy to open their kitchen and answer to all the questions we might have about their work.
The next chapter will focus on the relationship between geophysics and geomodeling.

The CSPG and the CWLS are great sources of information about petrophysics, with their courses, their technical presentations and the papers they published.
The Reservoir magazine houses several papers or series of papers about petrophysics through the year. Among them we have a series on FMI data published in 2015 and the always popular papers written by our colleague Ross Crain for years now.
Ross’ website is also considered a very good source of information by the many in our industry. It is definitely worth a look (www.spec2000.net).
