Advanced Models: Analytical & Numerical

In addition to the analytical models accessed via the Wizard and Models menus, advanced analytical models, advanced numerical models, and the advanced hybrid model are available within the Model Manager on the Advanced Models tab.

Analytical models assume single-phase flow. They support the simultaneous analysis of multiple flow periods. Data from different flow periods may be viewed simultaneously on the derivative and specialized plots. The analytical models support drawdown / buildup and injection falloff test types.

The numerical models have automatic grids, designed to provide an ease-of-use similar to the analytical models, while accounting for the complexities of multiphase flow. Currently, the numerical models are only functional for drawdown / buildup test types.

The hybrid model is essentially a numerical model, but with certain modifications to significantly reduce computation time, so that it is almost as fast as an analytical model.
