Ideally, geomodelers should work closely with other team members, and particularly with geologists. Geologists will bring a lot of information about the reservoir as their work efficiently combine geological, petrophysical, geophysical and engineering data with considerations such as paleodepositional environments, diagenesis and burial history. Geomodelers should not replace a geological interpretation by a cold, purely mathematical logic but respectfully translate the geological interpretation in a mathematical language understood by software.

(Pyrcz and Deutsch, 2014) and (Ringrose and Bentley, 2015) contain more details about using vertical, horizontal and 3D proportion facies data in geostatistics.

Geomodeling software provide powerful 3D visualtization tools that are helpful for geologists and other team members to improve understanding of reservoir characteristics, also 3D models are easy to explain geological characteristics to management and non-technical stakeholders.

The next chapter will focus on how petrophysicists and gemodelers collaborate together.
