Objectives: The course subjects cover a broad scope of geomodeling applicable to offshore, onshore mature, and unconventional 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.
Topics to be defined and discussed:
Geomodeling today is integral to a successful business strategy in many 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 well planning, uncertainty analysis, and in a variety of decision making processes. A key goal in the Geomodeling practice is to provide an image 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 offshore, onshore mature, and unconventional 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. Additional reading material will be listed in the notes.
• Geologic Concepts: heterogeneities, stratigraphic architecture, geometries
• 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 and choices:
• Essential statistics and terminology as reference material
• Compiling and checking the input databases, data types, e.g. well markers, logs, seismic.
• Defining the stratigraphic framework
• Modeling Facies, Petrophysics, Permeability, Geomechanics
• Post-processing for summarizing uncertainty and connectivity; well placement
• Volumetric assessments with constraints
• Re-scaling for the simulator
• Linking static to dynamic behavior
David Garner has more than 30 years of continuous technical experience in the industry with over 20 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 geomodeler and trainer and an associate of Geovariances in Fontainebleau, France. Previously Mr. Garner held positions 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. As a volunteer, Mr. Garner currently serves as a co-chair for the CSPG Geomodeling Technical Division committee and is chair of the upcoming Gussow conference, Closing the Gap III Advances in Geomodeling for Petroleum Reservoirs to be held in September, 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
