Reservoir Geochemistry

Audience

Petroleum geologists, reservoir geologists and engineers involved in the assessment of reservoir heterogeneity and connectivity; petroleum exploration geochemists who wish to expand their knowledge into reservoir geochemistry.

Content

  • Introduction to general concepts
    • Reservoir fluid properties and characteristics
    • Rate and mechanism of reservoir filling and mixing
    • Engineering versus geochemical nomenclature
    • Hydrocarbons and non-hydrocarbons
    • Relationship of hydrocarbon composition to petroleum properties
    • Analytical methods
  • Applications of petroleum geochemistry to the understanding of reservoir fluid
    • Tested oil: Interpreting gas chromatograms and GC-MS; non-hydrocarbons/ interpretation; application to reservoir continuity/connectivity
    • Gas: Non-hydrocarbon gases (compositions/sources); hydrocarbon compositions/interpretations; isotope studies
    • Water: API analysis; Stiff diagrams; action on reservoir matrix; effect on hydrocarbon composition/petroleum properties; water in sub-surface (variations/perturbations)
    • Residual oil: Extraction data/interpretations (relationship of poroperm and logs; interpreting fractionation, GC-MS; oil-saturated non-flowing reservoirs; tarmats and reservoired oils)
