Potential of the Eastern Jeanne d’Arc Basin, NL, Canada

The underexplored Eastern Jeanne d’Arc appears prospective for oil and gas, after new regional seismic data validates the extension of know plays in the area.

The objective was to provide petroleum resource estimates for the area using 2D/3D basin modelling for play risk analysis and volume estimates.

Regional sequence stratigraphy and geodynamic work coupled to a Forward Stratigraphic Model (DionisosFlow™) helped to map the extension of reservoirs, carrier beds and seals. Source rock potential was assessed using the FSM model to estimate deposition and degradation of organic matter during early burial.

After calibration of the thermal and fluid flow regime temperature, maturity and pressure, an integrated 3D model was built using TemisFlow™ to estimate the oil and gas charge in the potential traps (stratigraphic and structural) in the various plays.

The resource assessment of the Eastern Jeanne d’Arc area demonstrates a potentially prolific petroleum system. The uncertainty on HC volumes is given by the distribution of unrisked volumes in place. The range varies from 2.1 BOE to 9.8 BOE. The Probability of Geological Success is estimated to 11%.
