How to quickly estimate steam drive oil recovery
A short-cut, graphical method has been developed which permits relatively rapid estimation of oil that may be recovered from a steam drive project. In order of their use, the graphs necessary to make an estimate are as follows: (1) plot of steam saturation pressure vs. saturation temperature; (2) heat loss curves used to determine bottomhole steam quality; (3) plot of bottomhole heat injection rate per bbl of water equivalent vs. injection steam pressure (with original reservoir temperature and bottomhole steam quantity as additional parameters); (4) plot of formation volumetric heat capacity as a function of porosity and water saturation; and (5) graphic solutions to the Marx and Langenheim equations relating time, area steamed, and rate of steam front advance. In an example calculation all necessary reservoir rock and fluid properties are given, and the use of the graphs is illustrated.
