Who Should Attend

Entry level geoscientists and engineers working in the subsurface characterization of fluvial and clastic shallow marine depositional environments.

Description

Geoscientists and Engineers are responsible for characterizing the subsurface and often, with limited datasets. The use of analogs is critical for understanding the geologic variability that can and does occur.

The Texas Gulf Coast provides an excellent modern analog for fluvial and shallow marine reservoirs in the subsurface. Modern analogs provide spatial context for the areal geometry and variability that occurs within their respective depositional environments. This course will provide participants with a hands-on experience to understand how depositional environments and processes influence geometries and preservation potential of these systems to aid in their characterization in the subsurface as aquifers, reservoirs, and storage.

Learning Outcomes

·        Introduction to fluvial/shallow marine processes, depositional environments and preservation potential.

·        Spatial understanding of geometries for these depositional systems as they relate to subsurface characterization.

·        Fundamental concepts of facies and their impact on reservoir quality, distribution and volumetric calculations.
