- Method for determining well locations, or drainage areas, within a hydrocarbon reservoir for the exploitation of this reservoir. - Drainage zone configurations are generated randomly, generating for each configuration locations for each drainage zone. The locations of each drainage zone are determined to optimize a quality criterion, using an iterative optimization algorithm in which: for first iterations, the quality criterion is evaluated by means of a flow simulator , and for subsequent iterations, an approximate quality criterion evaluation model is constructed, the quality of this approximate model is evaluated, and the quality criterion is determined using the approximate model or the flow simulator. according to the quality of this model approached. |
