Oil and gas Tier 2

Marval O’Farrell Mairal finds favour for its ability to bring an ‘out-of-the-box perspective’ to its oil-and-gas work. The experienced group is well versed across the full hydrocarbons supply chain, from exploration and production through to midstream and downstream issues. On the transactional side, the team kept busy advising on bid rounds, farm-in agreements and restructuring matters. It also has a prominent position in regulatory and contentious work, with recent roles on several high-profile disputes for companies such as Roch and Shell. High-profile figure Francisco Macías is an oil-and-gas expert, who advises on transactions, contracts and regulatory issues. M&A and capital markets partner Ricardo Beller is noted for oil-and-gas transactions. Senior associate Jimena Montoya is also recommended for her focus on energy work.
