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

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
