Graphical technique for interpolating shape factors for peripheral waterflood systems

A method of interpolating the shape factors between already known sets of data can be utilized in peripheral waterflood systems. This graphical technique should provide reasonably reliable shape factors without necessitating further flow pattern evaluation. A set of interpolated shape factors for the constant pressure difference case is tabulated. These factors were derived from the shape factors previously determined using variation of width technique. A comparison of the interpolated shape factors and the shape factors obtained by the circling-in techniques are also shown. Good agreement was obtained in this comparison.
