OTC Brasil 2025 attracts over 23,000 participants in Rio de Janeiro
Event surpasses expectations with 250 exhibitors and over 3,200 delegates, fostering strategic debates on the Equatorial Margin, energy transition, and innovation
Rio de Janeiro, October 30, 2025 – The Offshore Technology Conference (OTC) Brasil 2025 concluded this Thursday (October 30) at ExpoRio, exceeding expectations and reaffirming its position as the largest and most influential offshore energy event in Latin America.
During the closing session, Petrobras President Magda Chambriard was honored on behalf of the company for the Búzios 7 Project, recognized for its successful implementation of technological innovations benefiting the offshore industry. “We are about to produce 1 million barrels per day in the Búzios field. We believe Búzios can reach 2 million barrels,” said the executive. Located in the pre-salt Santos Basin, Búzios produced 821.88 thousand barrels per day (bpd) in August, surpassing Tupi for the first time as Brazil’s largest oil-producing field, according to ANP data.
Over three days, more than 23,000 visitors from 53 countries filled the event’s 16,800 m², turning it into the epicenter of discussions on the future of energy and connecting Brazil’s expertise in deepwater operations with renewable energy innovation.
The success of OTC Brasil 2025 was also measured by the quality of its discussions. The conference gathered over 3,200 delegates – a high-level audience of executives, experts, and government representatives – who packed the technical sessions and plenary panels. The exhibition area hosted more than 250 companies and 47 sponsors, representing the entire oil, gas, and energy value chain and showcasing cutting-edge technologies and services.
High-level debates were the highlight of the conference, addressing strategic topics for the future of Brazil — including the development of the Equatorial Margin, the role of natural gas in energy security, the potential of offshore wind, and advancements in CCUS (Carbon Capture, Utilization and Storage) and decarbonization.
Innovation emerged as a cross-cutting theme, with a strong emphasis on Artificial Intelligence and digitalization to enhance efficiency and safety. In parallel, the iUP Innovation Connections, IBP’s innovation hub, stood out by connecting startups, investors, and large companies to accelerate digital transformation in the energy sector.
“The impressive attendance and the high-level debates — particularly on the Equatorial Margin and energy transition — show that the sector is united and ready to lead the social and economic development Brazil needs,” said Roberto Ardenghy, President of the Brazilian Petroleum, Gas and Biofuels Institute (IBP). “The record number of delegates and the strong international presence reflect the quality of our technical program. We brought the world’s top experts to Rio de Janeiro, showcasing the strength of Brazilian engineering and the country’s central role in the global energy landscape,” he added.
iUP Innovation Connections
