- Integrate geochemical interpretations into holistic petroleum systems analysis.
COURSE CONTENT:
Day 1. Fundamentals of petroleum geochemistry. Sampling and analytical techniques.
Learn composition of natural gases/oils, sampling/analytical techniques for source rocks, petroleum fluids.
- Petroleum composition/phases
- Interpretation of natural gases
- Interpretation of oils
- Post-accumulation processes
- Sampling techniques
- Analytical techniques
Exercises: interpretation assignments, matching oil samples with whole oil GC traces.
Day 2. Petroleum exploration and drilling the prospect.
Discussion of source rocks. Participants interpret quality/potential of source rocks, model petroleum expulsion. Exploration drilling, data necessary to interpret outcomes of exploration projects.
- Source rock presence, maturity, potential
- Expulsion from various organofacies
- Prediction of fluid properties in exploration projects
- 1D burial history/maturity
- Fluids/pressure
- Petroleum seeps
- Oil-source correlations
Exercises: mapping/interpreting source rocks; building expulsion profiles for various source rocks; constructing pressure profiles in subsurface; oil-source correlation.
Day 3. Appraisal, development, production, environmental and downstream projects.
Integration of petroleum geochemical data with subsurface datasets for appraisal, development/production of petroleum reservoirs. Discussion of petroleum spills/leaks. Creates value in downstream projects.
- Reservoir compartmentalization
- Time-lapse geochemistry
- Production allocation
- Petroleum spills/leaks
- Oil value
- Gas value
Exercises: unravelling compartmentalization of a reservoir; determining sources of oils collected after major offshore spill.
Participants are required to bring their own laptops.
