Reservoir Geochemistry


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.


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 fluids:
- 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)

Learning Objectives

This course is intended to provide geoscientists with an understanding of the concepts of reservoir geochemistry from fluid properties through to analytical methods. As well as how petroleum geochemistry can be applied to reservoir fluids.
