Craig participates in teaching, training, research and consultancy in:
- Harnessing Decision Analysis and Event-Based Risk Management tools to improve business performance, and to help focus and integrate geoscience, engineering and economic studies.
- Practical handling of uncertainties in geoscience and engineering workflows, including quantitative use of analogue data and use of Bayesian logic.
- Understanding, monitoring and improving recovery in oil and gas fields, including geochemical surveillance and production monitoring.
- Unconventional oil and gas production mechanisms, including heavy oil, shale gas and shale oil.
- Quantification of compartments and compositional variations in oil and gas reservoirs and hydrological systems using integrated pressure, density and compositional data combined with modelling of mixing processes.
- Diagenesis and prediction of reservoir properties.
- Natural tracers for natural and human-induced processes.
