By the end of this workshop, participants will be able to:
- Understand the key components of a petroleum system, including the source, reservoir, seal, and trap.
- Apply basin analysis, regional geology, and play-based exploration techniques to identify prospective areas.
- Recognize different types of hydrocarbon traps, from structural to stratigraphic, and their formation.
- Comprehend how a petroleum prospect is defined, evaluated, and assessed for risk.
- Integrate seismic data, well information, and outcrop geology for effective exploration.
- Understand how petroleum geology informs the appraisal and development of a hydrocarbon discovery.
