As a team, its availability and strong ability to work under pressure without making mistakes was the key to our success, especially when compared to the counterpart firm, which made many unforced errors, due to pressure from its own client.

Also, very important, was the rapid coordination with other teams within the firm, which were always available with 24 hours notice, which allowed us to resolve additional issues related to the energy practice in extraordinary times.

We value lawyers for their respect, commitment and professionalism, to name just a few key attributes that added significant value to their work, and to the transaction itself.

Associates Andres Felipe Parra and María Alejandra Salamanca, guided by partner Claudia Navarro, comprised the main energy team that supported us during the transaction. As to these three lawyers, the word exceptional falls short, as they were an immeasurable contribution to the success of the transaction.

With a strong track-record in both the conventional and alternative energy spheres, the practice is particularly noted for its a growing focus on projects involving renewable sources for clients such as Grenergy, among others. High-profile specialist Alvaro José Rodríguez possesses extensive experience in energy and environmental law and is particularly sought after for his expertise in the oil-and-gas arena; he recently advised Oxy (through its subsidiary Anadarko Colombia Company) in a farm-out agreement with Ecopetrol for the transfer of a 40% stake in four offshore blocks.

The group also draws on deeply experienced practice director Diana Salazar, who splits her practice between insurance, and energy and natural resources; and Erika Serrano Rojas, who was promoted to director of the firm's environmental and sustainability practice in March 2023.

Practice head(s):

Alvaro José Rodríguez; Mariana Sánchez


An excellent firm: knowledge, professionalism, availability… one of the best firms we have worked with in Latin America. Very detailed, they see things from all points of view, they don’t overlook any detail.

The treatment is really extraordinary from all the members of the team. They are very professional and know exactly what they are doing.

Their quality of work is unmatched; the promptness of the response – they are always timely.

I’d recommend the entire team of Mariana Sánchez.

Our operation is in the oil-&-gas sector. We operate a ‘tea pot’ refinery in Yopal Casanare. The hydrocarbons sector in Colombia is highly regulated, which is why one needs to be up-to-date with current regulations, not only regarding O&G but equally in environmental matters. The Posse team is highly specialised in these issues, in addition to having a constellation of technicians with whom a complete in-depth study of each topic is achieved. We are also building a solar park to self-consume and export energy, for which PHR are well-known stars.

What is outstanding about the PHR team in O&G, environmental and additionally in renewable energy – photovoltaic in our case – is the unconditional accompaniment and support. Their availability for us, 24/7. The team is mainly led and coordinated by partner Mariana Sánchez, with the additional and important support of Erica Serrano and Pablo Mejía. Great team. They are unconditional and attentive to detail, whether in contracting, regulation, etc.

Lawyers in the oil and gas area in Colombia must understand the engineering and geology aspects to effectively and correctly advise the client. In the case of CMS, Alvaro Josué Yáñez and Alvaro Yáñez Peñaranda have this particular competitive advantage over other lawyers in the sector.

100% success has been achieved with this team in each matter we have undertaken.

Given the complexity of the Colombian legal context in the oil and gas sector, billing has been in line with the peculiarities of the industry, being in my opinion fair both to the firm and to the client, unlike other offices that, due to lack of knowledge, charge more — or the charge is not adequate for the work.

My interactions have been with Alvaro Josué Yáñez and Alvaro Yáñez Peñaranda. We appreciate their in-depth knowledge of the sector, including their technical knowledge in refining, production, exploration, and transportation. In particular, I would like to highlight the professional ethics of both of them.

The team is knowledgeable and quick in their responses, which enables it to address clients’ needs in a very effective manner.

We distinguish the team’s lawyers for their dedication, professionalism and commitment.

It is an interdisciplinary team, with extensive and specialised experience in the energy, environmental, and land sectors, among others. The team is competitive, collaborative, and provides solutions with positive impacts. Lawyers seek to eliminate or minimise negative impacts.

The professionals in the team listen and understand the client’s needs, they help to make the execution of projects viable, and they are specialised people who constantly provide updates on the process. They are also available and provide exceptional service.
