Patent ID: 7561997

Claim:
A computer implemented method of generating a plurality of simulation results for an oilfield reservoir, comprising: obtaining a plurality of cases and a plurality of scenarios comprising a plurality of grid geometry parameters describing the oilfield reservoir; forming, using a computer, a plurality of simulator input files, each of the plurality of simulator input files comprising one of the plurality of cases and one of the plurality of scenarios wherein the plurality of simulator input files is stored in memory of the computer; generating, using the computer, a tree comprising a first case as a root node of the tree, a first scenario as a first child node of the root node, a second case as a second child node of the root node, and a second scenario as a child node of the second child node, wherein the grid geometry parameters of the first case and the second case are different, wherein the grid geometry parameters of the first case and the first scenario are identical, and wherein the grid geometry parameters of the second case and the second scenario are identical; storing the tree in the memory of the computer; selecting, using the computer, a subset of the plurality of simulator input files from the tree, wherein the plurality of scenarios includes the first scenario and the second scenario, and wherein the plurality of cases includes the first case and the second case; submitting the selected subset of the plurality of simulator input files to a simulator executing on the computer, wherein the simulator executes a simulation of the oilfield reservoir based on the selected subset of the plurality of simulator input files to generate the plurality simulation results for the oilfield reservoir; obtaining the plurality of simulation results; and displaying the plurality of simulation results on a display device of the computer.
