Darcy's law is the fundamental law of fluid motion in porous media published by Henry Darcy in 1856 ^[1].

q = -\frac{kA}{\mu} \frac{dP}{dL}

q

= Darcy's law flow area, cm²

h

= effective feet of oil pay, ft

k

= Darcy's law permeability, d

L

= Darcy's law length, cm

P

= Darcy's law pressure, atm

q

= Darcy's law flow rate, cm³/sec

\mu

= Darcy's law oil viscosity, cp
