The Sirius-2 well is situated in the GUA-OFF-0 offshore block, 77km from Santa Marta, the capital of Colombia’s Magdalena department.
During the test, samples were collected for laboratory analysis and initial results indicate a significant gas presence in the region.
Petrobras, operating through its subsidiary Petrobras International Braspetro – Sucursal Colombia, holds a 44.44% share in the consortium, while Ecopetrol owns the remaining 55.56%.
In December 2024, Petrobras and Ecopetrol announced the gas discovery in Colombia with the Sirius-2 well.

By GlobalDataThe Sirius-2 well has confirmed volumes exceeding six trillion cubic feet and is said to be the largest gas discovery in the country’s history. This find could potentially increase Colombia’s current gas reserves by 200%.
The well was originally named Uchuva-2 and is the second well drilled in the region after Sirius-1 (previously Uchuva-1).
The consortium will continue assessing the drilling results of the Sirius-1 and Sirius-2 wells in line with its plan and contractual commitments to Colombia’s Agencia Nacional de Hidrocarburos.
Also, in February 2025, Petrobras signed a strategic term contract with Bharat Petroleum Corporation to supply Brazilian crude oil grades.
Additionally, the company established cooperation agreements with ONGC Videsh and Oil India to explore oil and gas opportunities.
