Mayer Brown is noted for its background in oil and gas, LNG and energy transactions in Latin America. The firm represents some of the biggest Latin American businesses in the market, including Pluspetrol and CEMEX, and multinationals that are primarily focused on the region, such as CGX Energy and Frontera Energy. This Latin America focus has resulted in a stream of headline engagements, including advising Pluspetrol on the acquisition of Exxon Mobil Exploration Argentina from ExxonMobil Argentina Investments and QatarEnergy Argentina Holdings. Its Houston office houses a number of Latin America transactions specialists that also work in conjunction with the team in Brazil (through the firm’s association with Tauil & Chequer Advogados). The Latin America group features a number of natives from the region, along with bilingual and multi-lingual practitioners. Pablo Ferrante has emerged as a major player in Latin America oil and gas, LNG and energy transactions. Gabriel Salinas and Jose Valera are also prominent Latin America M&A specialists, while senior associate Federica Castro is another key member of the team. All named individuals are based in Houston.
