Numerical PI's are used to relate wellblock and wellbore pressures and the flow rate of a well in reservoir simulations by finite difference. This approach is based on an equivalent wellblock radius'', r[sub eq,o]. When nonuniform grids are used, r[sub eq,o] may create an error in wellbore pressure or oil rate. This paper presents a new well representation. The analytical solution for near-well pressure is included by modifying the transmissibilities between gridblocks so that flow around as well is described fully. The new method is applicable to non-uniform grids and nonisolated wells.
