Course Content

  • PETROLEUM SYSTEM CONCEPT OF UNCONVENTIONAL RESOURCES

      • Definition of petroleum systems: Conventional vs. Unconventional.
      • Characterization of these two systems in terms of elements, processes, timing, Oil & Gas composition.
      • Origin, composition, preservation and types of sedimentary organic matter: defining a typical source rock.
      • Oil & Gas generation, retention, expulsion and migration processes from source to reservoir rocks.
      • Introduction to Petroleum System Models: classical source rocks vs. unconventional source-reservoir rocks.
  • TIGHT SANDS

      • Tight sands at the basin scale: geological distribution and geochemical characterization.
      • Depositional settings, diagenesis and stratigraphy framework.
      • Definition of tight sand plays (tight gas) in a petroleum system perspective.
      • Characteristics: regional extent, diffuse boundaries, heterogeneities, low matrix permeability.
      • Porosity networks and their impact on fluid flow.
  • SHALE PLAYS

      • Definition of shale plays (shale gas, condensate, oil) in a petroleum system perspective.
      • Key geological parameters.
      • Integration of applied geochemical data (organic richness, Rock-Eval pyrolysis, estimating original TOC, vitrinite reflectance measurements, biomarkers, isotopes) and basin models (input, calibration and output) as a tool for defining “sweet spots” in existing plays (lecture, discussion and exercises).
      • Porosity system (organic and inorganic porosity) and impact on fluid flow.
      • Types of shale plays (tight, hybrid, fractured), impact on production (lecture and exercises).
  • RESOURCE APPLICATIONS: CASE STUDY

      • Confirmed North American plays: Barnett, Bakken, Eagle Ford, Marcellus, Montney.
      • Other potential worldwide plays: Vaca Muerta, Bazhenov, North Africa, Posidonia.

Learning Objectives

  • At the end of the course, participants will be able to:
  • integrate both geological and geochemical data to identify potential targets in unconventional petroleum systems,
  • acquire a global knowledge of existing unconventional resources, mainly tight sands and shale plays,
  • understand the exploration implications in this recent domain and future potential impacts.

Ways & Means

  • Interactive courses and exercises.
  • Examples with the most known unconventional reservoirs in the world.
