Permeability – How big is the difference?
The ability, or measurement of a rocks’ ability, to transmit fluids
The fluid: 12 oz of your favorite soda
The “rock”: 8” long straw
“Reservoir Pressure”: 15 psi (1 atm)
Case 1 - Permeability = 1 milliDarcy
Case 2 - Permeability = 1 nanoDarcy
How long to drain the “reservoir”?
Case 1: 527 days
Case 2: 9,624 years
