A method of recovering viscous petroleum from tar sand formations utilizing a deviated steam injection well with pump-down (through the flow line) completion. The steam injection well may use side pocket mandrels with constant flow or orifice regulators to control steam injection rates into the surrounding viscous petroleum formation. A plurality of pumping wells are situated along the drill path of the steam injection well and substantially above injection points for recovery of the fluidized petroleum.
