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 images of reservoir heterogeneities critical to better understanding the physical hydrocarbon extraction processes. Geomodels help reveal the impact of the various reservoir multi-scale features on dynamic behavior.

The course subjects cover a broad scope of geomodeling applicable to most reservoirs. The course intent is to provide 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. 

Topics to be defined and discussed: 
 • Geologic Concepts: facies, heterogeneities, stratigraphic architecture, geometries
 • Summary of essential Geostatistical topics 
 • Geomodeling Cases
 • Multi-scale data and rescaling topics
 • Properties in Models: discrete and continuous variables 
 • Modeling Uncertainty: The importance and introduction to approaches 
 • Post-processing Geomodels: practical use of multiple realizations with objectives
 • Introduction to multi-variate data analysis topics, classification and machine learning

Basics to be highlighted -The modeling process has many important steps, best practices and choices:
 • Essential statistics and terminology
 • Compiling and checking the input data types
 • Defining the stratigraphic framework and grid system
 • Modeling Methods for Facies, Petrophysics, Permeability, Geomechanics 
 • Post-processing for summary statistics, uncertainty, and connectivity; well placement
 • Volumetric assessments with constraints
 • Avoiding bias in results
 • Re-scaling methods for the simulator
 • Linking static to dynamic behavior 
Who Should Attend:
Technical people and decision makers working on subsurface hydrocarbon reservoirs in multi-disciplinary teams using or considering using geomodeling. This includes geologists, geophysicists, petrophysicists, reservoir engineers, technologists, technical managers and geomodelers. 

Learning outcomes: 
An introductory grounding in geomodeling thought process, best practices, fundamental geostatistical concepts, tools of the trade for using geomodeling or geostatistical mapping, and subject knowledge to enhance team collaboration. Improved understanding of the uses and limitations of geomodeling. The course manual provides useful reference material for your future modeling.

Lecture course. Isatis.neo, the premier geostatistical software from Geovariances will be provided for exercises with a complimentary one month license. 

None specifically. Openness to seeing a balance of theory and new concepts.


David Garner has more than 30 years of technical experience in industry with 24 years in applied geostatistical studies in petroleum and mining. He has published and presented over 25 papers, many of which were peer-reviewed. Currently, he is a consulting geomodeling advisor and trainer and an associate of Geovariances in Fontainebleau, France. Previously Mr. Garner held positions in Halliburton as a Chief Scientist in R&D, as a Specialist in Statoil’s Heavy Oil Technology Centre-Unconventionals R&D, as Senior Advisor Geologic Modeling for Chevron Canada Resources, and Reservoir Characterization Specialist at ConocoPhillips Canada. He was president of TerraMod Consulting for 6 years applying geostatistics and geomodeling techniques mainly for large international reservoir studies and mining resources. As a volunteer, Mr. Garner currently serves as a co-chair for the CSPG Geomodeling Technical Division committee and was chairman for three CSPG Gussow conferences, Closing the Gap I, II, and III: Advances in Geomodeling for Petroleum Reservoirs held in 2011, 2014, and 2018. He co-edited of the special edition December 2015 BCPG on Geomodeling Advances and the 2013 CSPG Memoir 20. He served a board term as CSPG Finance Chair. 

Mr Garner is registered as a Professional Geophysicist (P.Geoph) through the Alberta’s Association of Professional Engineers and Geoscientists (APEGA). -
