Finite Element Simulation of Oil and Gas Reservoir In Situ Stress Based on a 3D Corner-point Grid Model

Figure 6

Case study of the preprocessing procedure: the corner-point grid without inactive grid blocks (left column) and with inactive grid blocks (right column, the cyan grid blocks are active and blue ones are inactive); the finite element grid nodes (black dots) and grid blocks (cyan cells); every color refers to a individual material attribute and every grid block has a unique color (some colors are duplicated due to limited number of colors); every grid block has a unique material attribute.
