The Complete Geomodeling Course

Geomodeling today is integral to a successful business strategy in most hydrocarbon reservoirs. The sub-surface team uses the Geomodel to render the geologic interpretation into a digital format suitable for input to reservoir simulation software, for resource evaluations, for well planning, as part of uncertainty analysis, and in a variety of decision making processes. A key goal in the Geomodeling practice is to provide digital images of reservoir heterogeneities critical to better understanding the physical hydrocarbon extraction processes, to improve flow models. Geomodels help reveal the impact of the various reservoir multi-scale features on dynamic behaviour.  

The course subjects cover a broad scope of geomodeling applicable to most reservoirs. The course intent is to introduce sub-topics with grounding in fundamental theory, in geomodeling thought process, and to place high level topics into their basic integrated context. By the end of the course, each topic will have been defined and discussed and related to general workflows with examples. Many challenges faced by modelers in sub-surface teams will be discussed. Additional reading material will be listed in the notes. 

Importance of goemodeling?

Geological models are built for many different purposes, but common to all of them is a desire to build a representation of the formation at the subsurface. Geomodeling today is integral to a successful business strategy in most hydrocarbon reservoirs.
