COURSE DESCRIPTIONInterpret fluids/source rock data to add value to projects from exploration to environmental remediation in both conventional/unconventional petroleum systems world-wide.

  • Fundamentals of petroleum composition/properties.
  • Sampling of rocks, fluids.
  • Analytical techniques to evaluate potential of source rocks, composition of petroleum fluids.
  • Characterization/risking of source rocks, prediction of fluid properties in exploration prospects.
  • Interpretation of data from drilled exploration wells to assess value of discovery.
  • Assess reservoir compartmentalization during appraisal/ development.
  • Geochemical surveillance of oil & gas production.
  • Locate producing intervals, allocate petroleum production.
  • Identify oil sources for petroleum spills/leaks.

 

LEARNING OUTCOMES:

  • Identify/propose geochemical solutions.
  • Design cost-effective sampling/analysis programs for source rocks, petroleum fluids.
  • Construct expulsion profiles for different types of source rocks.
  • Predict fluid properties, product value in exploration/production wells.
  • Correlate oils to source rocks.
  • Interpret origin of hydrocarbon/non-hydrocarbon natural gases.
  • 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.
