Abstract
This paper is intended to study the 3D modeling of hydraulic flow units and associated well placement layouts applicable to heterogeneous oilfields. We present a clusterwise approach that seeks to identify volumes that confine “sweet spots” taking into account two versions for the flow zone indicator, namely FZI and FZI*, which are quantities statistically distributed throughout the porous medium and computed through linear regression. Rock clusters are determined by using distinct permeability averaging rules in order to verify the responses of the clustering in locating high fluidity zones. Additionally, production wells are placed strategically at points determined by each approach. Layouts are then contrasted after performing long term flow simulations in a fully implicit black-oil solver provided by the MRST (Matlab Reservoir Simulation Toolbox) toolbox. We have concluded that the permeability averaging rules have a considerable impact over the produced oil volume not only for layouts obtained with the same flow indicator, but also for layouts compared vis-à-vis between the two flow indicators.
