Abstract:
Disclosed are methods for simulating pressures and saturations of oil, gas, and water in an oil reservoir with production and injection wells, which include (1) using of new approximating linear algebraic (finite difference) equations that more accurately represent actual pressures by basing the equations on new functional forms: ln(r) or 1/r, (2) solve the set equations using by defining a coarse grid array and a fine grid array nested in the fine grid array, and solving the coarse grid array and using the resulting solution to fix points in the fine grid array before it is solved, and (3) defining and solving a dynamic grid array based upon constant saturation contours.
