摘要：Abstract The energy transition and reactivation of mature oil fields may even being seem as bipolar topics, within the theme of energy. However, regarding to the sustainability, these topics can be analyzed in parallel to the approach to the inherent risks involved in the supply chain, associated with energy transition. This study talks about the energy transition, connecting the risks associated with its implementation (focusing on supply chain) and discusses how adversely the promotion and reactivation of inactive areas are affecting or contributing to advances in sustainability discussions. Studies out of international agencies reports of energy and sustainability were made, also from organizational reports applied to the energy transition, and scenery analysis of the reactivation of producing oil fields, considered economically marginal.
