In recent years, unconventional hydrocarbons (UH) have been playing an increasingly important role in the world's energy supply. In the Peruvian case, the potential of the Muerto formation in the Lancones basin as an unconventional reservoir has been investigated. Although there are extractive activities in the study area, one of the factors that have limited the performance of activities in the hydrocarbon sector is social conflict. This problem stems from stakeholders' fear of environmental contamination, health, and the degradation of the resources necessary for the population's subsistence (water) caused by extractive activities. For this reason, it is important to carry out an adequate evaluation of the social impact of an oil project at an early stage. In this sense, information was collected on the main concerns of the stakeholders based on the results of the Environmental Impact Study of oil block XXIX. The gray clustering methodology was applied, which allowed evaluating the social impacts associated with the exploration and exploitation of a hypothetical UH oil project in the Lancones basin, located in the Piura region, northwest of Peru. The main result of the work indicates that the project is perceived negatively by the stakeholders in the project's area of ​​direct influence. The most critical concern being access to water, both for human consumption and for agricultural activity. The State, like the oil company, must give priority to access to water resources to avoid potential social conflict. In addition, these results will help the local and national governments to make better decisions about the management of social conflicts associated with a future UH project.
