An oil recovery process employing a well pattern having a horizontal well located along each of the four sides of a substantially rectangular well pattern, a vertical injection well located at the center of the well pattern, and four vertical infill wells located midway between the central injection well and the four corners of the rectangular well pattern. Steam is initially injected through the central injection well and production taken at the four infill walls. After the injection of about 0.5 to about 1.0 pore volumes of steam through the central injection well, central injection is converted to water, the infill production wells are converted to steam injection, and production is taken from the horizontal wells.
