Numerical Reservoir Simulation
Definition - What does Numerical Reservoir Simulation mean?
Numerical Reservoir Simulation, also known as Reservoir Simulation, is a process performed in order to estimate the performance of a reservoir in real time i.e., when a well is drilled and production starts. The Numerical Stimulation predicts the flow of liquids in the reservoir (oil, gas & water) through porous media once the production starts. These real-time simulations are studied using computer models which calibrate the data based on numerical equations and predict the behavior of reservoir once the production starts.
Petropedia explains Numerical Reservoir Simulation
Numerical Reservoir Simulation falls under reservoir engineering and these simulation models are used when any development of new field is to be made by E&P organizations. Numerical Reservoir Simulations also help in taking investment decisions as it predicts the possible production forecasts from a reservoir. In Reservoir Simulations, a numerical model is built upon petro-physical and geological characteristics of a reservoir and analysis are performed. This simulation consists of three parts, which are:
- Geological model – It is in the form of volumetric grid having cell/face properties that predicts porosity of the rock formation.
- Flow model – It predicts and analyzes how fluids (typically oil, gas & water) will flow from a porous medium.
- Well model – It describes how the fluids will flow from the reservoir into the wellbore.
