Sequence Stratigraphy Applied to Petroleum Exploration & Production

This course is dealing with concepts and applicationsof sequence stratigraphy for petroleum exploration and production. Faciesanalysis in different depositional regimes will be interpreted withinexploration and production framework. The different approaches of sequencestratigraphy will be discussed. Sequence stratigraphy applications in petroleumsystems will be highlighted in terms of source, reservoir and trap distribution.Exercises will assist the understanding of sequence stratigraphic surfaces,systems tracts and depositional sequences based on well log cross-sections andseismic lines.


  • Historical development of sequence stratigraphy
  • Other types of stratigraphy: chronostratigraphy, biostratigraphy,event stratigraphy.
  • Methods of sequence stratigraphic analysis: outcrop, core,well logs and seismic data
  • Workflow of sequence stratigraphic analysis
  • Accommodation and shoreline shift. Relative sea-levelchanges; transgressions; forced regressions; normal regressions
  • Parasequences


  • Sequence stratigraphic surfaces: subaerialunconformity, correlative conformity, basal surface of forced regression,regressive surface of marine erosion; maximum regressive surface, maximumflooding surface, transgressive surface of erosion, flooding surface, drowningunconformity
  • Systems tracts: highstand, falling stage, lowstand andtransgressive
  • Types of stratigraphic sequence:
        • Depositional sequences
        • Genetic stratigraphic sequences
        • Transgressive-regressive sequences
  • Stratal geometry and carbonate factories


  • Hierarchy of sedimentary cycles
  • Cyclo and event stratigraphy
  • Time attributes of straigraphic surfaces
  • Sequence models of fluvial and deltaic systems


  • Sequence models of:
        • Coastal toshallow-marine.
        • Deep-waterclastic systems.
  • Sequence stratigraphic analysis of carbonatesystems

  • Sequence models of shallow- and deep-water carbonatesystems
  • Applications to sequence stratigraphic systems:
        • Marine carbonate sourcerocks
        • Case studies insequence stratigraphic and 3D reservoir architecture
