Visualization of Reservoirs’ Hydrodynamic Models

Abstract

The article describes visualization methods of hydrodynamic models. Main purpose of seam examination is to predict its status and to find ways of increasing final oil recovery. Modeling of the oil reservoir allows increasing accuracy of reservoir properties and geological structure of the seam during history matching, as well as choosing the best strategy of reservoir management. Geometry of the modelled oil seam (called grid) is represented via the finite number of elements or cells that determine size and volume of the oil reservoir. The more elements used for reservoir volume approximation, the more detailed are the simulation results. However, increasing the accuracy of modeling leads to bigger amount of computation and higher memory usage, therefore final geometry is a compromise between computational complexity and accuracy.

Geometry elements may be presented in various forms that influence the modeling accuracy. One of the simplest ways is to present cells of the grid as uniform cubes. The article presents a method of creating cell geometry for reservoir hydrodynamic models with the use of “corner points” that allows achieving better accuracy.
