This 6-day field workshop visits spectacular outcrops along Victoria’s Otway Coast in SE Australia between Port Campbell and Anglesea. The field geology is integrated with seismic, remote sensing, potential field, well and thermal history data and the workshop includes lectures on basin evolution, stratigraphy and structure. The aim is to teach exploration and development geologists, geophysicists and engineers the skills needed to analyse the evolution, stratigraphy, structure and petroleum systems of a basin, and to assess its hydrocarbon potential. The sequence stratigraphy and depositional environments of outcrops are examined, including stratigraphic sections measured in the field. The outstanding extension, inversion and strike-slip structures observed are analysed to determine the nature and timing of events and their influence on deposition. Each area utilises nearby seismic sections to illustrate key aspects of the structure, stratigraphy and basin evolution.

Intended learning outcomes

  • Measuring structural sections and determining trap style in the basin
  • Measuring stratigraphic sections and interpreting environment of deposition and oil potential including; aeolian dunes, fluvial, lacustrine + coals, shallow and deep marine shale, limestone and sandstone, with condensed sequences.
  • Relating field observations to seismic, well, thermal history, remote sensing, potential field and topographic data to infer petroleum systems
  • Analysing extension, inversion and minor compression with strike-slip
  • Determining 2D and 3D stratigraphic relationships and variations
  • Observing and predicting onlap onto variably deformed and eroded surfaces
  • Assessing source, reservoir and seal potential
  • Summarising the basin's tectonic evolution and its relevance for resources.

Generic skills

  • Exercise critical judgement
  • undertake rigorous and independent thinking;
  • adopt a problem-solving approach to new and unfamiliar tasks
  • develop high-level written report and/or oral presentation skills
  • interrogate, synthesise and interpret the published literature
  • work as part of a team.
