Play Fairway Concept
•• For a given depositional sequence A For a given depositional sequence A Play FairwayPlay Fairway is the is the present day area of a potential reservoir unit, with the possibipresent day area of a potential reservoir unit, with the possibility lity of having a complete working petroleum system (seal, charge of having a complete working petroleum system (seal, charge and trap)and trap)
•• Play Fairway AnalysisPlay Fairway Analysis examines relative risks and total volume examines relative risks and total volume potentialpotential
•• Play Fairway AnalysisPlay Fairway Analysis examines four play components (reservoir, examines four play components (reservoir, seal, charge, trap)seal, charge, trap)

Biostratigraphy
• New analyses (team work)– Micropalaeontology, nanofossil,
palynological– 900 samples, 6 wells
• Review of existing analyse 14 wells
• Integrated with seismic to develop a sequence strat. framework

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
Salt Structural Interpretation
• 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

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)
