Summary:
Steam injection, one of commercial technologies widely used to develop heavy oil reservoir, has brought reservoir engineer’s
attention to improve performance of waterflooding, light oil reservoir and enhance its oil recovery. Sarto reservoir, located at
the transitional belt in Daqing Oil Field, is the case of steam injection utilized. It is a typical multi-layer sandstone fluvial and
deltaic deposit with depth of 1000~1200m, permeability of 500~2000md and porosity of 20~30%, surface oil viscosity of
50~100cp @ 50oC, wax content of 25~30% and freezing point of 30~35 °C.
