This study describes a graphical method for calculating oil recovery by steamflooding that permits accurate prediction of fluid-saturation profiles and oil-bank formation. The oil displacement calculation is based on the Buckley-Leverett method for isothermal, 2-phase flow in porous media. The fluid-flow theory is used with the Marx and Langenheim method to predict the size of a steam zone from energy balance and heat transfer considerations. The method is more complex than previous simplified methods, but permits hand calculations of fluid saturation profiles and the delay of oil-bank arrival in producing wells for partially depleted oil reservoirs. These computations are in excellent agreement with those calculated numerically. Since uniform vertical displacement is assumed, this method is suggested for use only for thin sands. (10 refs.)
