A method of steam injection, through a horizontal well bore having a well liner, to stimulate oil well production. A first step involves providing an injection opening density in the well liner with a plurality of small injection openings that are distributed substantially constantly over the length of the horizontal well bore. The injection opening density must be greater than a cross- sectional area of the well bore and less than 0.3% of the area of the well liner. A second step involves injecting steam along the horizontal well bore and into the formation through the injection openings at pressures that are marginally greater than reservoir pressure.
