Petrobras and Ecopetrol confirm Colombia’s largest-ever gas discovery

Petrobras, through its subsidiary Petrobras International Braspetro B.V. (PIB-COL), and Colombian energy giant Ecopetrol have unveiled what experts are calling a game-changing development for the country’s energy sector. The Sirius-2 well, located 77 kilometers off Santa Marta’s coastline, has revealed an estimated 6 trillion cubic feet (Tcf) of gas in place. This discovery is poised to reshape Colombia’s natural gas industry, potentially increasing the nation’s reserves by 200%.

The drilling operation, which commenced on 19 June 2024, marks the most significant natural gas discovery in Colombia’s history. Situated within the maritime block GUA-OFF-0 at a water depth of 803 meters, the Sirius-2 well underscores the untapped potential of Colombia’s offshore resources. Petrobras and Ecopetrol’s partnership leverages cutting-edge technology to explore this resource-rich area, setting the stage for a transformative impact on regional energy production.

Unlocking Colombia’s natural gas potential

The estimated volume of natural gas identified in the Sirius-2 well has drawn widespread attention for its potential to bolster Colombia’s energy independence. Experts believe this discovery could redefine the country’s energy landscape by significantly reducing reliance on imports while supporting sustainable economic growth.

The consortium, led by Petrobras with a 44.44% stake and Ecopetrol holding the remaining 55.56%, plans to invest USD 1.2 billion in the exploration phase, with an additional USD 2.9 billion allocated for production development. Petrobras has confirmed that its share of the investment is already incorporated into its 2025–2029 Business Plan.

If commercial viability is confirmed, production is expected to begin by 2027, contingent on securing environmental permits. The innovative “subsea to shore” development approach will connect four offshore wells directly to an onshore gas treatment facility, ensuring efficient and environmentally conscious extraction. Once operational, the field is projected to produce 13 million cubic meters of natural gas daily for at least a decade.

A transformative discovery for Colombia’s energy future

The discovery of the Sirius-2 well is not just a milestone for Petrobras and Ecopetrol but a defining moment for Colombia’s energy sector. Analysts predict this gas find will drive significant economic benefits, from job creation to increased foreign investment. It also aligns with global trends toward cleaner energy sources, as natural gas is considered a key transitional fuel in the shift from coal and oil.

The consortium has committed to ensuring that all exploration and production activities are carried out responsibly, with Petrobras emphasising its adherence to Colombian regulations and environmental guidelines. Petrobras representatives noted the importance of engaging local communities throughout the development process, ensuring that the project benefits both the environment and society.

Expert perspectives on sustainable energy

Energy industry analysts have highlighted the Sirius-2 discovery as a prime example of how partnerships between major corporations can unlock new energy frontiers. Experts point to the advanced technology and collaborative approach employed by Petrobras and Ecopetrol as key factors in the project’s success.

The discovery also comes at a time when Colombia is exploring ways to strengthen its energy security amid rising global demand for natural gas. By tapping into offshore resources, the country is positioning itself as a significant player in the global energy market, while contributing to the regional transition toward more sustainable energy practices.

Looking ahead

As Petrobras and Ecopetrol embark on the next phase of development, the Sirius-2 well stands as a testament to the potential of Colombia’s offshore energy resources. With a USD 4.1 billion investment roadmap and cutting-edge infrastructure plans, the discovery is poised to drive economic growth and strengthen the nation’s energy independence for decades to come.
