Bazán Cambré & Orts is an energy boutique with an international oil-and-gas client base that turns to the firm for support on transactional, regulatory and contentious matters. The practice is particularly well-known for its focus on upstream oil-and-gas work and oilfield services. Nicolás Dilernia is well-versed in industry-specific contractual, corporate and regulatory matters; and Leandro Orts handles work involving the commercial aspects of oil-and-gas law. The firm can also turn to the highly-regarded oil-and-gas veteran Mario Orts, who has decades of industry experience and is frequently called on to provide expert witness testimony for international arbitrations. Former corporate partner Maria Victoria Tiscornia, known for her expertise in oil-and-gas contracts, has left the firm for an in-house role at natural gas company CGC.
