Oil and gas Tier 1

For many, Martínez de Hoz & Rueda is ‘the best oil and gas firm in Argentina’.

Sources highlight the firm as ‘phenomenal in energy transactions’, where it is routinely called upon by oil-and-gas majors to advise on M&A, bidding rounds, joint ventures and financing matters. On the exploration side, it is advising ExxonMobil, Equinor Argentina and Mitsui on the development of their respective hydrocarbons’ businesses in Argentina, while on the infrastructure front, it is currently advising on several pipeline projects. It is also known for its formidable weight in the arbitration space and it frequently represents international oil companies in complex investment disputes and commercial arbitrations. José Martínez de Hoz co-heads the energy group — he also leads the arbitration practice — and is widely revered for his first-class experience and market profile. Energy department co-head Pablo Rueda is also highly regarded for his broad oil-and-gas expertise, which spans transactional, regulatory and environmental matters.
