Claim One:
1. A computer implemented method of computerized simulation, in a computer system including at least one master node and a plurality of processor nodes, of a reservoir model of a property of the subsurface reservoir structure, the reservoir model being simulated being partitioned into a number of cells arranged in an organized system of cells, the simulation further being based on predicted values of input parameters for the cells of the reservoir, the predicted value of the input parameter being generated on a random basis and having a specified degree of uncertainty, the method comprising the computer processing steps of: (a) receiving input parameter data about subsurface features of the cells and the reservoir in the master node; (b) transferring a petrophysical algorithm to the processor nodes for determining a postulated value of the property of the reservoir cells; (c) distributing the input parameter data for individual cells from the master node among the plurality of the processor nodes; (d) determining a postulated value of the reservoir property for individual ones of the reservoir cells in individual ones of the processor nodes; (e) transferring determined postulated values of the reservoir property for the cells from the processor nodes to the master node for storage in the data memory on completion of the step of determining by the individual ones of the processor nodes; (f) repeating the steps of distributing, determining and transferring for the cells of interest in the reservoir model; and (g) assembling in the memory the postulated values of the reservoir property for the cells of interest in the reservoir.
