The computation of flowing well bottom-hole pressure from the pressure of the block containing the well, or the computation of well flow rate when the flowing bottom-hole well pressure is specified, are important considerations in reservoir simulation. While this problem has been addressed by several authors, some important aspects of the problem ae not adequately treated in the literature. An analytical method is presented for computing the well block factors (constants of the productivity index) for a well coated anywhere in a square or rectangular block. Equations for well geometric factors and well fraction constants are given for grid blocks of various types, containing a single well, encountered in reservoir simulation studies. The equations given can be used for both block-centered and point-distributed grids in 5- and 9-point (2-dimensional) finite difference formulations. However, the radial flow assumption utilized in deriving the equations is not always strictly valid. For most practical situations it provides an adequate approximation for near well flow. 12 ref.).
