This thesis presents the results of 2D Petroleum System models using PetroMod software on four shelf-to-slope regional seismic lines (NovaSPAN 1100, 1400, 1800 and 2000), by incorporating new data from the Nova Scotia Department of Energy-sponsored Play Fairway Analysis and outcrop data from Aït Moussa in the Middle Atlas, Morocco. In each of the four models, different source rock variables (hydrogen index and total organic carbon) were used based on data from Aït Moussa. Results suggest Lower Jurassic source rocks in the Scotian Basin, if present, are within the oil maturity window in the southwest and in the gas maturity to overmature window to the northeast. The transformation ratio (organic matter to hydrocarbons) for each kerogen type shows subtle variations along the margin but overall increases towards the northeast of the margin.
