This paper presents new equations that account for non-volumetric effects of
limited aquifers on production data analysis of single phase oil reservoirs by
defining a new material balance time function. This new time function and material
balance time help us to introduce flowing materialbalance (FMB) equations for such
reservoirs. Validity of these equations is justified using analytical solutions. For
development of analytical solutions, special simplifying assumptions are considered.
To justify these assumptions, comparison is made using a commercial numerical
reservoir simulator across some ranges of reservoir parameters.Furthermore, it is
shown that the given FMB equations are applicable for any irregularly shaped
reservoir which is partially contacted with a non-cylindrical limited edge aquifer. For
such reservoir geometries, numerical solution is used for justification. This is
followed by introducing a simple equation for estimating average reservoir
pressure.
