Brazil’s state-owned oil giant Petrobras has confirmed the significant gas potential of its offshore discoveries in the Guajira Basin, Colombia, estimating around 6 trillion cubic feet (Tcf) of recoverable natural gas. These discoveries were made in the Uchuva-1 and Uchuva-2 wells, which have been renamed Sirius-1 and Sirius-2, respectively. The Uchuva-1 discovery occurred in 2022, followed by Uchuva-2 in 2024.
Petrobras, operating through its subsidiary Petrobras International Braspetro B.V. – Colombia, holds a 44.44% stake in the consortium formed in partnership with Ecopetrol, which owns 55.56%. According to Petrobras, these estimates confirm the magnitude of the finds and their strategic importance for Colombia’s gas market. However, additional studies will be necessary to assess the commercial viability of the reserves fully.
The consortium plans to continue its operations in line with the planned schedule and commitments to Colombia’s National Hydrocarbons Agency (ANH). These developments are part of Colombia’s broader efforts to bolster its natural gas production and secure energy independence.
The discoveries come at a critical time, as the world focuses on cleaner energy sources and natural gas is increasingly seen as a key transition fuel. If commercially viable, these fields could play a vital role in ensuring energy security for Colombia, while positioning Petrobras and Ecopetrol at the forefront of Latin America’s gas supply chain.
