Module 6: Conventional Reservoir Geochemistry

Learning Objectives:

• Reasons for differences in fluid compositions

• How reservoirs are filled and mix
  - Shell, BP models

• Paragenetic history/Fluid inclusions as means of determining reservoir filling history
• Compositional grading – methods and examples
• Reservoir connectivity and compartmentalization – methods and examples
• Estimating fluid residence times
• Effects of in-reservoir alteration on petroleum - biodegradation theory and examples, water washing, phase separation, tar mats, fluid contacts
• Fluid properties prediction
• Non-hydrocarbon gases introduction
• Solids problems; e.g., wax, asphaltenes, soaps, hydrates
• Production Monitoring and Allocation
  - Complementary inorganic geochemical methods
