Martínez de Hoz & Rueda

A dominant force in the country’s oil-and-gas industry, Martínez de Hoz & Rueda is a reference point for local and international clients seeking advice on oil-and-gas exploration, production, transportation, distribution and marketing. Operating out of offices in Buenos Aires and Neuquén (Argentina’s shale gas industry hub), the team has also carved out a market-leading position in relation to hydrocarbon concession extension agreements and renegotiations, and is active in unconventional hydrocarbons operations and the development of LNG projects too. The firm’s large roster of retained international clients also rely on the team for support on multi-party, multi-contract commercial arbitrations arising out of cross-border transactions. The formidable energy law veteran José Martínez De Hoz brings vast hydrocarbons and associated arbitration expertise to the table. He co-leads the practice alongside fellow oil-and-gas industry stalwart Pablo Rueda and dynamic younger partner Tomás Lanardonne, who fronts the firm’s Neuquén base and has wide ranging transactional and regulatory expertise. From a strong associate bench, Marcos Blanco (oil-and-gas, project finance, M&A, and dispute resolution) and Valeria Celesti (hydrocarbons matters) are both noted. Since publication, Blanco has been raised to the partnership – effective January 2024.
