Abstract

This article presents new equations for the calculation of interblock geometric factors and a bulk volume of blocks in radial-cylindrical coordinates for both a block-centered grid and a point-distributed grid. The new equations require the knowledge of logarithmic spacing constant (αlg) only for interblock geometric factor calculations and logarithmic spacing constant (αlg) and radius of pressure points (ri) for bulk volume calculations. The new equations are derived from those available in the literature, but are simple and do away with the estimation, in the radial direction, of one set of block boundaries for transmissibility calculations and another set of block boundaries for bulk volume calculations.
