摘要：The sonic profile is used mainly in exploration wells due to the fact that it provides greater investment in data acquisition because these wells serve as a reference for analyzing the petroleum potential of the area. To be considered for exploitation, racing sonic tools are usually not used in wells for economic reasons, especially in times of low oil price. Since it is not economically feasible to purchase a sonic profile for the vast majority of older wells, mainly due to the cessation of oil production, one must resort to other means to solve the problem. One way is to use statistical methods that generate a sonic profile, like the synthetic sonic profile, to establish estimates of seismic velocities of rocks along the wells. Thus, this study aims to determine a model that generates synthetic sonic profiles in oil wells drilled in the geologic units belonging to the Sergipe-Alagoas sedimentary basin and which is within the required quality standards.
