Fernando Xavier

With 18 years of legal experience, 15 of them exclusively dedicated to the oil, natural gas and biofuels sector, Xavier leads the E&P and downstream niche at Machado Meyer. Over the past years, he has successfully coordinated more than 50 deals involving the negotiation of E&P assets, far more than any other partner of ranked firms. He has already provided legal assistance to clients of virtually all areas regulated by the Brazilian Oil Agency–ANP, having participated in the development of a series of important leading cases in the industry. His practice stands out in administrative litigations and other complex-regulation issues that require both technical and legal expertise (operational security, local content, fuel specification, non-conventional hydrocarbon resources, etc.). He also has a solid experience in the provision of legal assistance on regulatory and contractual matters related to the biofuels sector, including projects involving ethanol, biodiesel and second-generation biofuels.
