Reservoir & Development

The Standard Workflow:

G & G Interpretation workPetrophysics

Static Geological Reservoir Model

Dynamic Simulation Model

To achieve

• Reservoir Management & Economic Decisions• Development & Operating Strategy• Reserve & Range Estimates• Recovery Mechanism• Optimise Well Planning• Sensitivities of Static & Dynamic Parameters (e.g. Ø, NTG, Aquifer,...) • Uncertainty & Risk Management
