摘要
A method for conducting a stress calculation is disclosed adapted for modeling a set of stresses and displacements in a reservoir, the method comprising: (a) building a reservoir model over a region of interest by gridding the region of interest, the grid being comprised of one or more cells and having nodes, each cell having a cell center; (b) interpolating unknown rock displacements in the region of interest from cell centers to grid nodes; (c) integrating over each cell to form a discrete system of equations; and (d) using the discrete system of equations to model the stresses and displacements in the reservoir.
