Regional PhaseFinder Package: Greenland

Offshore Greenland is largely unexplored. The occurrence of source rocks is known exclusively from field work performed mainly by GEUS in eastern Greenland. Onshore these span the timeframe from Devonian to Cretaceous and lacustrine to marine depositional environments.

Critical elements of basin evolution include the presence, maturity, distribution and characteristics of individual source rock intervals.

The petroleum plays in eastern Greenland are largely undefined. Western Greenland basins suffer in addition from the lack of direct source rock evidence. Extrapolation from outcrop samples taken in the east is the only solution.

GeoS4's Greenland PhaseFinder package allows the combination of source specific compositional predictions of petroleum, following the PhaseKinetic approach (di Primio and Horsfield, 2006), with petroleum system modelling. The correct reproduction of petroleum phase behaviour represents a major step forward in modelling fluid generation, migration and accumulation in this complex setting.

Deliverables

• Accurately predicts GOR, Formation Volume Factor, Saturation Pressure and API Gravity in time and space
• Includes PhaseKinetics data (di Primio and Horsfield, AAPG Bulletin, 2006) for eight selected source rocks from the study area
