RESUMO

The main objective of history matching is to improve numerical models of oil fields by incorporating observed data, production and pressure, into the characterization process, in order to obtain more reliable production forecasting. This technique presents some limitations mainly in the beginning of the development of oil fields, when less information is available and higher uncertainties are present. With seismic 4D, it is possible to obtain saturation maps allowing the improvement of the numerical model yielding a more reliable production forecasting. The objective of this work is to developed a methodology to improve the numerical model through the incorporation of the saturation maps in the process of history matching. The process requires a higher number of critical parameters to be analyzed in the adjustment process; therefore, it is necessary to increase the number of simulations yielding a more complex procedure. An alternative to minimize this problem is the statistical design and response surface methodologies which allow to study many variables and regions at the same time. It is possible to optimize some answers simultaneously, improving the process by reducing the manual work yielding better results
