Introduction Volumes and Uncertainty

Risks and uncertainty Prospects and Plays Assessing risks & volumes

  • regional geology,
  • petroleum systems
  • hydrocarbon plays

Prospect maturation workflow Risk profiles Ranking prospects Risk mitigation

2
Session

Traps and Reservoirs Traps

  • Risks and uncertainties
  • Important hydrocarbon settings
  • Trap types in rifts

Reservoirs Risks and uncertainties important hydrocarbon settings Reservoirs types in:

  • rifts
  • passive margins
  • deltas,
  • carbonate provinces
  • deep-water settings

Session

Seals, Pressures and Charge

Mechanisms of seal failure Seals and pressures in:

  • important hydrocarbon settings
  • in rifts

Impact of source rock types and timing issues for Charge assessment Charge in important hydrocarbon settings Source rocks charge in rifts

Session

Risk assessment

Volume assessment Dependencies between:

  • prospects in a portfolio,
  • risking and volume assessment of prospects
  • reservoir-seal pairs,

Probabilistic prospect Statistical estimation of volumes

Session

Exploration economics

Assessing economic value of prospects Exploration economics Geophysical evidence POS on DHIs (Probability of Success influence on Direct Hydrocarbon Indicators) and/or (+/-) evidence from CSEM (controlled source electromagnetics)– consistent with Bayes’ theorem
