Most reservoir engineers with more than 20 or 30 years experience have probably made pseudo relative permeability curves (or pseudo curves for short) at one point or another in their careers.
The use of pseudo curves was widespread back in the days when computer power was particularly costly and slow. Nowadays the art of making pseudo curves is becoming a forgotten trick of the trade, it seems.
But with small simulators such as ExcSim, pseudo curves provide indispensable ways to capture specific physical behavior accurately, even in coarse reservoir models.
The video below demonstrates an easy and quick way to generate such pseudo curves. The simulation model is a 5-layered model with varying petrophysical properties, and is controlled by constant bottom hole pressure at both the injection and production sides of the model.
