This paper reports on analytical techniques that were used to study improvement of gas/oil gravity drainage by steam injection in a densely fractured dome-shaped low-permeability reservoir containing viscous oil. Aspects of the process studied include mixing of the steam and hydrocarbon gas, the temperature distribution in the caprock and reservoir, and oil production by thermal expansion and gravity drainage. The models developed are applied to the Qarn Alam reservoir of Oman, which may be a candidate reservoir. The steam-injection process appears very attractive for this reservoir; an oil/steam ratio of 0.5 m{sup 3}/Mg may be achieved.
