RI 6760 Computer Techniques For Calculating Shape Factors And Channel Volumes From A Potentiometric Model For Use In Waterflood Performance Calculations

A computer program is presented to calculate the shape factors and volumes of cells from a potentiometric model, using coordinates of the inter-sections of the stream lines and equal potentials and a few additional coordinates. Shape factors are used in flow computations when the geometry is complicated. The program also includes computer instructions to divide the channels into cells of equal volume and to obtain the shape factor for each of these equal volume cells. An illustrated example using the potentiometric model for the waterflood of a seven-spot well-spacing pattern is presented. The information contained in the report is of value not only to those allied to the subject but also to others, because many of the techniques can be conveniently used in formulating other computer programs.
