Campos Mello Advogados

Delivering ‘service of the highest legal quality’, the oil and gas offering from Campos Mello Advogados encompasses regulatory, M&A, litigation, environment, tax, banking and finance, and labour advice on issues affecting all segments of the value chain. A conscious focus on LNG projects, including regasification initiatives to supply gas for consumers and thermal power plants, is supplemented by proficiencies in energy transition matters, particularly in biorefining, carbon capture storage (CCS), and carbon markets. Rogerio Campos was brought in from Veirano Advogados in July 2023 to strengthen the team’s capabilities in offshore E&P. Former co-heads Alexandre Bittencourt Calmon, Marcelo Frazão, and João Marçal Martins left the firm in November 2024, along with a group of other partners and associates. The firm strengthened its oil and gas offering in September 2025 following the integration of Schmidt, Valois, Miranda, Ferreira & Agel Advogados and its capable team: Paulo Valois, a firm favourite of national and international oil companies and financial institutions for M&A, project development, and tenders promoted by ANP; Rogério Sobral De Miranda, whose business law acumen proves advantageous in M&A, joint ventures, contractual matters, and project finance, jointly lead the team; Sonia Agel, whose prior experience in the public sector as a federal state attorney and as general counsel for ANP stands her in good stead in regulatory matters and judicial and administrative litigation; Isabela Faria, who is the principal point of contact for project financing; and Eduardo Cirne Lima, a corporate specialist well versed in M&A, corporate restructuring, and commercial contracts.
