Petrobras has confirmed the largest gas discovery in Colombia’s history at the Sirius-2 well, located 77 km offshore in 830 meters of water. The discovery exceeds 6 trillion cubic feet of gas, potentially boosting Colombia’s reserves by 200%.
Production will begin with four wells, targeting 13 million cubic meters per day over the next decade. Petrobras owns 44.44% of the block, with Ecopetrol holding the remainder.
The consortium plans $1.2 billion in exploration and $2.9 billion in production investments, aligned with Petrobras’ 2025-2029 Business Plan. While the gas will serve Colombia’s needs, Brazil will benefit economically as Petrobras operates the project, and Brazilian professionals may contribute to its execution.
This discovery in the Guajira Offshore Basin, characterized by Tertiary sediments, is geologically distinct from Brazil’s Equatorial Margin. Operational logistics, such as OSVs, are expected to come from the U.S., given the proximity, says Anidio Correa, R&D – Environment Projects Lead at WSB Advisors.
