Regional PhaseFinder Package: West Greenland

Offshore Greenland is largely unexplored. The occurrence of source rocks is known from field work performed mainly by GEUS in eastern Greenland, and recently also from western Greenland. Onshore these source rocks 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 western Greenland are largely undefined. The source rock samples from West Greenland and Northern Canada were provided by GEUS, Denmark's national geological survey.

GeoS4's West 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 three selected source rocks from the study area
