Highlight geologic concepts (e.g., mechanical stratigraphy, rock properties, faults, folds, etc.) that control natural fracture development in conventional and unconventional reservoirs

Demonstrate characterization methods that incorporate the use of 3D seismic data for improved mapping of mechanical facies and fracture properties (i.e., increased value of information)

Discuss workflows that combine geologic and geomechanics concepts, petrophysical properties, and seismic attributes within geological models in preparation for reservoir simulation

Quantify the combined effect of fracture properties (intensity, orientation, width) and local stresses in effective flow properties of simple fracture scenarios

Course Content

Natural fractures may be conductive in conventional reservoirs or may become conductive after hydraulic stimulation in unconventional reservoirs. This course addresses these concepts by examining datasets from both conventional and unconventional systems and presenting workflows to construct naturally-fractured reservoir models. Particular attention is given to the use and calibration of 3D seismic attributes, sound stratigraphic and structural frameworks, and geomechanical information. Models and concepts are examined in the context of how they impact fluid flow, reservoir simulation results, field production, and forecast. This 2-day course will present the workflows that have been developed along with spreadsheet-based exercises to solidify concepts. The course provides in-depth presentations and discussions of the models presented.
