Conventional Versus Unconventional Resources:


Conventional ReservoirsUnconventional Reservoirs (Shale)
Localized structural trap"Continuous-type" deposit
External HC sourcingSelf-sourced HC
Hydrodynamic InfluenceMinimal hydrodynamic influence
Porosity ImportantPorosity may not be important
Permeability > 0.1 md
Permeability << 0.1 md
Permeability f(p)Permeability = f(p)
Traditional Phase behavior (PVT)Complex (HP/HT) PVT
Minimal extraction effort
Significant extraction effort
Significant production history
Limited production history
Often late development life-cycle
Early development life-cycle
Few wells for commerciality
Many wells for commerciality
Base reserve for voumetrics
Base reserves on analogs
Assess entire prospect before drilling
Prospect driven by drilling
Boundary-dominated flow (months)
No boundary-dominated flow
