Potential of the Eastern NL, Canada

The Flemish Pass Basin recently gained attraction with major oil discoveries (Mizzen, Bay-du-Nord).

This study reports a full Geological & Geophysical study aiming at constraining a Petroleum System model to access the hydrocarbon resource potential and risking for the area in the November 2015 license round.

The architecture of the basin is constrained to provide a sound stratigraphic framework for the model.

These input data allowed a DionisosFlow™ forward stratigraphic model to be built with 890 layers in a 4x4 km grid and spanning the Tithonian to the base tertiary at a 0.1 Ma resolution. The calibrated model returned a 3D grid of lithologies. The lithological grid was upscaled in 23 time layers to feed a 1x1 km grid TemisFlow™ Petroleum System model to assess in-place resources. Two main and proven source rock intervals are considered in the model: Kimmeridgian and Tithonian (type II-III).

The timing of maturation and expulsion and migration is compatible with oil and gas entrapment in 4 main plays (Tithonian, Berriasian, Valanginian and Aptian).

Hydrocarbon resources reach a cumulated 12 Bbbl of oil and 113 Tcf of gas unrisked trapped in the Flemish Pass Basin. Associated CRS mapping provided Probability of Success (POS) associated to these volumes.
