Abeledo Gottheil Abogados

Abeledo Gottheil Abogados is best known for its expertise in oil-and-gas disputes and is sought out for advice on complex commercial and international arbitrations, as well as domestic contentious matters. The team also handles transactional work in the sector, providing due diligence and antitrust support. The practice is co-led by Hernán Martín Oriolo, who has advised on big ticket oil-and-gas M&A for more than 20 years and is highly experienced in arbitration and litigation in the industry; and Sergio Porteiro, who covers energy regulation and contractual matters. The team can also call on the expertise of vastly experienced oil-and-gas veteran Luis Erize; with senior Florencia Buczak – who provides arbitration, litigation and legal advice to oil-and-gas companies – the primary contact at associate level. Since publication, the firm has announced the hire of Nicolás Martín Mordeglia; with over 20 years' in-house experience across both the mining and oil-and-gas sectors (most recently as legal head of the Argentine mining operations of Arcadium Lithium), he arrives as of counsel - effective as of July 2024.
