Claim One:
1. A computer implemented method of computerized simulation, in a computer system including a master node, a plurality of processor nodes and a data memory, of a reservoir model of a reservoir property of a 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 a petrophysical algorithm determining the reservoir property from predicted values of input parameters for the cells of the reservoir model, 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 the petrophysical algorithm from the master node to the processor nodes for determining a postulated value of the property for the cells of the reservoir model; (c) distributing the input parameter data for cells of the reservoir model from the master node among the plurality of the processor nodes; (d) determining postulated values of the reservoir property for the cells of the reservoir model in individual ones of the processor nodes according to the transferred petrophysical algorithm and different predicted values of the input parameters; (e) transferring determined postulated values of the reservoir property for the cells of the reservoir model 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; and (f) assembling in the data memory the determined postulated values of the reservoir property for the cells of the reservoir model.
