Module 9: Petroleum Geochemistry

Petroleum Geochemistry: Well Site Gas Analysis

Learning Objectives:

  • Understand the origin of the gases collected during the drilling processes
  • Awareness of wellsite gas data: how it is collected on a rig and measured
  • Understand how the data is reported by service companies
  • Explain the origin and significance of wellsite gases and what corrections are required to maximise the geological signal.
  • Awareness of how to use gas data to spot pay zones
  • Understand what cause changes in associated and non-associated gas composition’s
  • Example of how to correct wellsite gas data and calibrate it to PVT data
  • Appreciate where it can go wrong:
  • Reservoir vs non-reservoir zones
  • Impact of coring
  • Drilling induced effects
  • Linkage to Pore Pressure
  • Examples & some recommendations on set up
