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, essential 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.

Course Overview
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 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

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 

Exercises: limited to a few by-hands examples.

Prerequisites:  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 the Gussow conference, Closing the Gap III Advances in Geomodeling for Petroleum Reservoirs held in 2018.  He was general chair for the CSPG 2011 and 2014 Gussow conferences, co-editor of the special edition December 2015 BCPG on Geomodeling Advances and the 2013 CSPG Memoir 20. Other courses taught are Fundamentals of Geostatistics, All You Need to Know about Geostatistics, Deconvolution Theory, and Introduction to Geophysics

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