A method, system, and computer program product for performing oilfield surveillance operations. The oilfield has a subterranean formation with geological structures and reservoirs therein. The oilfield is divided into a plurality of patterns, with each pattern comprising a plurality of wells. Historical production/injection data is obtained for the plurality of wells. Two independent statistical treatments are performed to achieve a common objective of production optimization. In the first process, wells and/or patterns are characterized based on Heterogeneity Index results and personalities with the ultimate goal of field production optimization. In the second process, the history of the flood is divided into even time increments. At least two domains for each of the plurality of wells are determined. Each of the at least two domains are centered around each of the plurality wells. A first domain of the at least two domains has a first orientation. A second domain of the at least two domains has a second orientation. An Oil Processing Ratio is determined for each of the at least two domains, then an Oil Processing Ratio Strength Indicator is calculated. At least one Meta Pattern within the field is then identified. An oilfield operation can then be guided based either on the well and/or pattern personality or the at least one Meta Pattern.
