The contribution of the oil activity is beneficial for an economy even more in the region where the activity takes place. Therefore, the purpose of this research work is to determine the impact of PETROPERU's contribution on the growth of the Piura Region. This research is of a non-experimental design, semistructured interviews and is reinforced with econometric models. The basis of this art is based on the theory of the hydrocarbon sector in Peru and economic growth. It was found that the contribution of PETROPERÚ, as an important pillar of the Modernization of theTalara Refinery, is more important in the growth of the Piura Region than at the level of Peru. In this sense, it is important to maintain that the contribution is not only economic, but also benefits socially in different ways, from providing jobs to helping to reduce diseases.
