It is based on approximate analytical solutions for the 2D inflow performance of an infinite-conductivity fracture in a rectangular drainage area and the near-well pressure drop for flow to a circular well in a vertical cross-section of the reservoir. The method can accommodate reservoirs with arbitrary horizontal and vertical aspect ratios, off-center wells, permeability anisotropy and skin factors. Being simple and straightforward, the method can be readily implemented in a standard spreadsheet program. Well productivities for depletion at constant rate are always higher than at constant pressure. The difference can be as much as 22% for a fully penetrating well in a thin, isotropic reservoir. 1-4 Journal of Petroleum Science & Engineering 64 ARTICULO Hagoort, Jacques 37873 169690 169690 0 0 0 0 237509 BAAB BAAB 2026-03-05 200044498 0 200044498 2026-03-05 15:11:56 2026-03-05 ARTICULO
