Our History
Cataldo Energies is a strategic legal advisory firm focused on the energy sector, operating at the intersection of law, engineering and regulatory intelligence.
Founded by Sergio Cataldo, the firm was built upon a multidisciplinary foundation designed to address the legal, technical and economic complexities of energy markets, particularly in oil and gas and energy transition environments.
We advise clients navigating highly regulated and capital-intensive sectors, providing legal solutions that combine regulatory certainty, contractual robustness and long-term strategic vision.
Our approach is grounded in the understanding that oil and gas remain central to global energy systems, not only as primary sources of energy, but as critical enablers of investment and infrastructure for the transition towards lower-carbon alternatives.
Cataldo Energies operates as a trusted partner for companies seeking to expand, structure and protect their operations in a rapidly evolving global energy landscape.
Our Founder
Cataldo Energies was founded in 2024 by Chief Legal Officer Dr. Sérgio Cataldo, a lawyer with over 10 years of experience. He holds a law degree from UniverCidade Cândido Mendes (UCAM) and an electronic engineering degree from Centro Universitário da Cidade (UniverCidade). Dr. Sérgio Cataldo has always sought to integrate his technical and legal knowledge to provide innovative and comprehensive solutions to his clients.
He has specializations in Energy Law from UCAM – AVM and in Oil & Gas Law from the Catholic University of Petrópolis (FUNCEFET – UCP), in addition to pursuing a Master’s in Regulatory Law at UCAM.
However, his journey began much earlier, in 1982, when, as a young professional, he started his career at Petrobrás, working in platform maintenance. With an entrepreneurial vision and dedication, he excelled as an automation engineer and later led major projects, including the construction of an oil tanker and a platform with a capacity of 150,000 barrels. In 2002, he transitioned into contract law, where he identified the need for a lawyer with technical expertise, which motivated him to study law between 2008 and 2012.
In 2013, amid a challenging political and economic landscape in the energy sector, Dr. Sérgio Cataldo founded Cataldo Advocacia. Today, with a team of approximately 30 professionals, the firm provides high-quality legal support, ensuring that clients receive the best service and tailored solutions.
With Cataldo Advocacia well established, Dr. Sérgio Cataldo continued to strengthen his connection to the Oil & Gas sector, investing in his technical and cultural development. Fluent in Portuguese, English, and Spanish, he continuously works to bridge the gap between law and the energy industry. His expertise and global perspective prepare him to tackle the challenges of an increasingly internationalized market.
Cataldo Energies is a natural extension of Dr. Sérgio Cataldo’s commitment to innovation, ethics, and excellence—principles that guide our practice and drive our pursuit of efficient and sustainable legal solutions in the energy sector.
