A new numerical simulation method was developed to solve 2-dimensional reservoir problems of the type encountered in drilling and producing activities of a single well. The method includes more variables and is more generally applicable than any available method designed for individual well problems. Emphasis was placed on simulating reservoir behavior in the vicinity of the well bore. To achieve accuracy in computing pressures and saturations close to the well bore, very small flow cells were used. A fully implicit finite-difference scheme was developed to obtain numerical stability. The method was designed to simulate transient, 2-phase, cylindrical flow of oil and gas in porous media. Oil and gas compressibilities and viscosities and solution gas-oil ratios were permitted to vary. Gravity and capillary pressure were included in the calculations. Porosity, vertical permeability, and horizontal permeability were specified for each location in the reservoir. To demonstrate the practical applicability of the method, a computer program was written for the IBM 360/65, to solve several common individual well problems.
