Matthew J. Pranter Associate Professor of Geological Sciences Fellow, Energy and Minerals Applied Research Center Reservoir Characterization and Modeling Laboratory Research Interests Reservoir Characterization and Modeling Sedimentary and Petroleum Geology

Research

I am interested in carbonate and clastic rocks: their origin, distribution, and characteristics. My research involves the analysis of depositional systems, sequence stratigraphy, and sedimentology as applied to petroleum reservoir geology and geophysics and 3-D reservoir modeling. My students and I analyze various types of data (e.g., outcrop, subsurface) to describe, characterize, and model the stratigraphic architecture, facies, and heterogeneity of carbonate and clastic systems and reservoirs in order to assess the stratigraphic and sedimentologic controls on reservoir quality and distribution. My current research involves (1) the characterization and quantification of lateral reservoir-scale heterogeneity (petrophysical, geochemical, etc.) within carbonate facies and reservoirs using outcrop analogs; and (2) the analysis and quantification of sandstone/sand-body connectivity within fluvial and deepwater reservoirs. For these studies, detailed stratigraphic, sedimentologic, and petrophysical measurements and data from outcrops provide important analog information in the form of spatial, geometrical, petrophysical, and rock-fabric data to evaluate subsurface reservoirs and condition 3-D geologic models.

Check out the Reservoir Characterization and Modeling Laboratory and Energy and Minerals Applied Research Center websites for more information on my research in reservoir geosciences.

Geology field trip for Petroleum Reservoir Characterization and Modeling (GEOL 4550/5550) to the Piceance Basin of western Colorado. Excellent exposures of fluvial deposits of the Williams Fork Formation were the focus of the trip. Fieldtrip stop in Plateau Creek Canyon.

Courses

I teach undergraduate courses in Physical Geology and Earth Resources and the Environment (both approved for Arts and Sciences core curriculum: Natural Science), Hydrocarbon Geology, and a combined undergraduate/graduate-level course in petroleum reservoir geosciences.

		Introduction to Geology I - Physical Geology (GEOL 1010) provides an introduction to geological sciences. The course covers the composition and structure of Earth, its dynamic processes, and the role of geological sciences in our society. Link to the Course Website through CULearn Offered Fall 2009
		Earth Resources and the Environment (GEOL 3500) examines Earth's most important natural resources and their impact on society and the environment. Addresses the geology, occurrence, production, and use of petroleum, coal, mineral, and water resources. Future world energy supply and demand, conservation, and the transition from fossil fuels to renewable resources are discussed. Link to the Course Website through CULearn Offered Spring 2010
		Introduction to Hydrocarbon Geology (GEOL 3540) discusses the origin and distribution of conventional and unconventional petroleum and coal resources, source rocks, types of traps and seals, reservoir rock properties, exploration methods (seismic data analysis and interpretation, formation evaluation, subsurface mapping), reservoir characterization and modeling, reserves calculations. Link to the Course Website through CULearn
		Petroleum Reservoir Characterization and Modeling (GEOL 4550 / 5550) emphasizes concepts and methods of petroleum reservoir data analysis, integration, and modeling using subsurface information and outcrop analogs. The course addresses petroleum systems, drive mechanisms and recovery efficiency, reservoir properties, sequence-stratgraphic and structural controls on reservoir quality and distribution, flow units and reservoir zonation, and concepts and methods of 3-D stochastic and deterministic reservoir modeling.
