Salt Structural Interpretation

• Mapping distribution and depth to top and base of allochthonous and autochthonous salt

• Seismic interpretation of salt morphology and their evolution over time to develop predictive models for sediment distribution

• CNSOPB led initiative


• Research project to forward model salt dynamic processes to compare with the understanding of features seen on seismic data

• Dalhousie Geodynamics Group

Geochemistry

• Source rock evaluation

• Evaluation of thermal history of the basin

Geochemistry• 780 samples were collected at the GSC-

Calgary and submitted to TOC/Rock-Eval analysis.

• Another 60 samples were picked and submitted to Vitrinite Reflectance analysis.

• TOC/Rock-Eval analysis measures organic carbon content of the rock and other characteristics, which are used to identify hydrocarbon source rocks.

• Vitrinite Reflectance measures maturity

fluorescence in Ultra violet (UV) and at both ends of visible spectrum (green and red)

GLOOSCAP C-63 (4425 m)Petroleum Fluid Inclusions (PFI) usually exist along linear features such as cleavage planes

and fractures. They show fluorescence in Ultra violet (UV) and at both ends of visible spectrum (green and red)
