Summary

This course considers fluvial, alluvial fan and lacustrine depositional systems as exploration targets and in terms of field development. The controls on these systems will be assessed at a variety of scales to aid the understanding of the distribution of source rocks and reservoir units in continental basins. Topics covered include stratigraphic analysis and correlation, tectonic, climatic and base level controls on facies distributions, system-scale variations in sandstone body architecture, and dimensions and connectivity of reservoir units. Exercises based on subsurface data form a key element of this workshop.

Duration and Training Method

A three-day classroom workshop presented as a mixture of seminars, case study presentations, workshops discussions and exercises of varying duration in the classroom.

Participants will learn to:

  1. Understand the characteristics of alluvial fan, fluvial and lacustrine systems in sedimentary basins.
  2. Evaluate and integrate the controls on lacustrine and fluvial depositional systems.
  3. Develop tools for the prediction of field-scale distribution of reservoir units.
  4. Analyse the variation in stratigraphic architecture of fluvial successions in terms of connectivity within a reservoir.
  5. Evaluate the different scales of heterogeneity in fluvial successions and their effects on reservoir quality.
  6. Use appropriate correlation techniques in fluvio-lacustrine systems.
  7. Assess tectonic controls on basin margin alluvial fan characteristics.
  8. Integrate different data types in the analysis of continental depositional systems.

Who should attend

The course is aimed at relatively experienced exploration and development geoscientists, petrophysicists and reservoir engineers.

Prerequisites and linking courses

Participants are expected to have a background in clastic sedimentology. For those wanting an introduction to fluvial sedimentology and reservoir geology at the Basic Application Level there are courses N155 (Introduction to Clastic Depositional Systems: A Petroleum Perspective) and N156 (Clastic Depositional Systems in a Basinal Framework: Exploration and Reservoir Implications (Pyrenees, Spain). Course N108 Exploration and Geological Model Development in Fluvial Reservoirs (Ebro Basin, Spain) provides and opportunity to consider many of the topics covered in N387 in a field context and apply them to the building of reservoir models.
