Abstract
Summary For multiple-oil-zone reservoirs, steamflooding two zones at the same time is advantageous. Three methods for dual injection through a common wellbore were tested at Texaco's Kern River field in Bakersfield, CA. Because dual injection results in an excessive amount of heat transfer between injection streams, it was imperative to predict steam quality or water temperature at the sandface for each injection stream. To evaluate the merits of each method adequately, a computer model was developed to predict downhole temperatures, steam qualities, and pressures for each injection stream. Field tests of the three injection configurations provided measurements necessary for validation of the model. This paper describes the computer model, the field test, and the results from the three dual-injection scenarios.
