Well flow regime which creates steady state reservoir flow around the well and characterised by:

q(t) = q = \rm const

constant flowrate

p_e(t) = p_e = \rm const

constant formation pressure

p_{wf}(t) = p_{wf} = \rm const

constant bottomhole pressure

J(t) = J = \rm const

constant productivity index
