Course Length

3 days (light version) to 5 days (full version)

Target students

Geologists, geophysicists, and engineers actively working in exploration from regional studies to prospect generation

Learning Outcomes

  1. Incorporate methodologies and workflows with available datasets pertinent to describe and derisk reservoir source and seal elements at a basin and play scale

  2. Construct Gross Depositional Environment (GDE) and Common Risk Segment (CRS) maps

  3. Predict/estimate porosity evolution with burial and cases of exhumation

  4. Quantify timing of trap formation and migration with kinetic sequence stratigraphy

  5. Estimate biodegradation risk with temperature gradient/heatflow calculations.

COURSE OVERVIEW AND CONTENT

This course covers the basic concepts and methods applied to basin analysis in oil and gas exploration, and appraisal. All concepts are illustrated with examples of outcrop well-log, core and seismic data.

  • Introduction

  • Methods in Basin Analysis

  • Sequence Stratigraphy applied to Basin Analysis

  • Low- and high-accommodation fluvial systems

  • Incised valleys and lowstand deepwater clastics

  • Shoreline trajectory methodology, evolution of clastic- and carbonate-dominated margins

  • Basins during transgression

  • Prograding shorelines

  • Sequence stratigraphic framework below seismic resolution

  • Reservoir porosity prediction  with porosity versus depth plots, exhumation and potential improvement due to reworking

  • Carbonate-dominated basins

  • Growth Strata in compressional and extensional settings: implications for stratigraphic traps and structuring and migration/charge timing

  • Burial history, subsidence, heat flow, thermal gradients and biodegradation
