The history matching technique consists in modify the simulation model so that it reproduces the historical production and pressure observed. However, applying this technique in the early years of production of a field is rather limited, mainly due limited amount of information available. Currently, the tool that has helped minimize the problem of scarcity of information is seismic 4D. Some works, such as Risso (2007) and Ida (2009), have contributed to the development of methodologies that integrate seismic data to the history matching process in a quantitative way, promoting adjusted models more reliable. The focus of this research was application of pressure map in the history matching process during the parameterization of the problem in order to supplement the information of saturation map to better determine the heterogeneity of the reservoir. In the background was evaluated the influence of pressure map information during optimization as a parameter in order to improve the accuracy of the objective function. The validation of methodology proposed was done in a simple synthetic model and the application was done in the Namorado Field, modified with one geological fault and one channel with high permeability (AU)
