The effect of steam segregation within the wellbore on the distribution of steam over the injection interval and on the resulting steamflood performance was numerically investigated. Results included in this paper show that, because of gravity segregation, steam mass and heat distribution are nonuniform over the injection interval. The effect of steam segregation on predicted performance was important for heavy-oil reservoirs, especially when the vertical permeability was small compared with the horizontal permeability. In general, the segregation effect was more pronounced for reservoirs with high horizontal permeability (specific injectivity).
