4/π stimulated well potential

Brief

Stimulated well drainage

4/π is the maximum possible stimulation potential for steady state linear flow in a square well spacing.

Math & Physics

Steady state flow boundary conditions:

$P |_{x=1/2} = P |_{x=-1/2} = P_i$

$\frac{dp}{dt} =0\ for \ \forall x$

From Darcy's Law:
