Clastic Stratigraphy and Reservoir Characterization

Program Objectives

This comprehensive introductory course has been specifically designed to provide solid understanding of sedimentology, stratigraphy, and reservoir characterization concepts. Emphasis is placed on sandstone reservoirs. Participants will gain the knowledge foundation, experience, techniques and tools to interpret geologic data for integration into geologic and reservoir models. Multiple examples and practical exercises are included to link the material to exploration and development projects. The participants will learn the critical necessity of a multi-disciplinary approach to fully understand the reservoir. A progression is made from interpreting facies to defining reservoir flow units. Modelling is the link between the geologist and the reservoir engineer and is tied directly to successful reserve recovery programs. This class is a stepping stone to more advanced geologic training tied to increasing the productivity of existing and new-field development and to successful exploration programs. Participants will: 
  • Understand the physical processes that create clastic sedimentary rocks 
  • Define grain and bedform characteristics 
  • Understand the sedimentologic effects on reservoir porosity and permeability 
  • Interpret well and seismic data to identify key stratigraphic boundaries 
  • Define stratal geometries in relation to sequence stratigraphy 
  • Identify facies to flow units 
  • Predict facie associations within depositional environments 
  • Build framework 2D geologic models 
  • Integrate stratigraphic interpretation into 3D geologic models 
  • Predict source, reservoir, and sealing lithologies at basin or field scales 
  • Link stratigraphic interpretation to exploration and development projects 
  • Recognize compartmentalized reservoirs
