Mathematical and numerical properties of control-volume, finite-element [CVFE] scheme for reservoir simulation. R. Eymard and F. Sonier. SPE Reservoir Engng., November 1994, 9(4), 283--289.
The application is described of prismatic finite elements for 3-D full-field simulations. The grid is generated with automatic techniques that are popular in structural engineering and which result in numerical diffusion that is as isotropic as possible, hence, grid-orientation effects are controlled and accuracy is easily improved through natural grid refinement. Examples are given which show that for the same accuracy, computational costs are lower for results obtained with the CVFE scheme than for those obtained with finite-difference grids. 20 refs.
