O'Farrell’s oil and gas practice is known for providing crucial advice to domestic and foreign companies on significant legislative and regulatory changes that impact the energy industry. It has been involved in many high-profile deals, such as the acquisition of significant oil and gas reserves, the divestiture of assets, and calls for offshore tenders. The team also advises on the execution of energy distribution agreements and represents clients in complicated arbitration matters related to supply agreements. The practice is led by public law specialist Agustín Siboldi, who focuses on contractual, regulatory, and contentious matters, with honorary partner Uriel F. O'Farrell drawing on his long-standing experience to assist with M&A and privatisation transactions. Additional assets to the team include public lawyers Jorge Muratorio and Ana Belén Micciarelli, who handle disputes between oil and gas companies and the state, with the assistance of senior consultant María Fortuna and senior associate Rebeca Fernández, both experts in public law.
