Energy & Climate Change


The members in our practice have extensive experience in the oil & gas sector having worked not only as external consultants but as in-house lawyers for transnational oil companies as well as in the sector's regulatory entities. This experience allows us to provide counseling that is not only sound from a legal standpoint, but is also always practical and the most appropriate for our clients considering the extensive business knowledge that we have gathered. In oil & gas we have experience advising companies in the exploration phase, in development and production, transport and distribution of natural gas concessions, refineries, storage terminals, service stations and lubricant commercialization, including all the contracts associated to these businesses, including those associated with the regulated activities of transport and distribution of natural gas, supply and transportation of natural gas contracts, contracts for the use of pipelines, EPC contracts, license agreements, concession contracts, and all else related to the business, from the extraction of the hydrocarbons in the fields, all the way to its commercialization. Also, we have vast experience in the management of permissions and authorizations, liberalization of property and legal defense in administrative disciplinary proceedings.

The lawyers specialized in the electricity sector have also worked for important contracting companies and in the Ministry of Energy and Mines, with an excellent handling of the business during its generation, transmission and distribution phases, for both traditional sources and renewable energies, including all regulatory and contractual aspects associated with the electricity business.
