A formidable player in the mining sector, Allende & Brea has been working on growing its profile in the adjacent oil-and-gas sector, where it can leverage its full service capabilities, especially in the fields of tax, environmental law, contracts, M&A and financing in tightly regulated industries. Florencia Heredia, who is best known for her mining practice but also has experience across energy and the broader natural resources segment, leads the team; cross-border M&A financing partner Marcos Patron Costas, and associate Agostina Martinez (international oil-and-gas law, contracts and negotiations), are the other key contacts.
