Reservoirsimulation
Reservoir simulation is the numerical modeling of multiphase fluid flow through porous rock in an oil and gas reservoir to forecast production performance under different development strategies. The goal is to quantify pressure, saturation, and sometimes composition fields over time, given reservoir properties, PVT data, boundary conditions, and production controls.
Governing equations describe mass conservation for each fluid phase and are coupled through Darcy’s law, relative
Numerical methods used in reservoir simulation include finite-difference, finite-volume, and finite-element discretizations on structured or unstructured
Model types range from black-oil, which uses simplified fluid behavior, to compositional models that track multiple
Applications encompass production forecasting, history matching to reproduce past production data, optimization of development plans, and
