Colombia Found Enough Gas to Last a Generation. The Country Still Needs Diesel Today.
Petrobras and Ecopetrol confirmed the largest natural gas discovery in Colombia's history. The Sirius-2 well in the offshore Guajira Basin revealed over 6 trillion cubic feet of gas in place, enough to potentially double the country's existing reserves and rewrite its energy future.
It is genuinely historic news. It is also news that changes nothing about Colombia's energy situation in 2026.
The country that just confirmed a generational gas discovery is the same country where natural gas production fell 17% in 2025, where imports now cover nearly a third of domestic gas consumption, where crude oil output hit a five-year low earlier this year, and where the ELN carried out 14 pipeline attacks in August alone. Diesel prices jumped 13% in a single month in the UAE this week, a signal of how tight the global refined products market has become. And Petrobras itself has stated that Sirius-2 requires additional testing and studies before commercial viability can be confirmed. First production, in the best-case scenario, arrives in the early 2030s.
Colombia has found more gas than it has ever had. It cannot use any of it yet. This is not a contradiction in the news cycle. It is the defining tension of the Colombian energy market in 2026: a country sitting on historic reserves that are years from production, facing an immediate fuel crisis that is getting worse by the month.
The Sirius-2 announcement generated headlines about Colombia's energy future. What received less attention was the context in which that future sits. Ecopetrol is investing up to $7 billion in 2026, with 70% directed toward upstream. The new government has reversed four years of anti-exploration policy. The sector is genuinely reactivating.
But reactivation takes time. New contracts require environmental licensing, community consultation, in Sirius's case, 120 separate prior consultation processes with communities along the pipeline route, drilling, completion, and infrastructure build-out before a single barrel reaches the market. That timeline is measured in years, not quarters.
In the meantime, Colombia produces crude oil it exports at commodity price and imports diesel at market price. That gap is not a forecast. It is the daily operational reality for every mining company, power generator, maritime operator, and industrial business running on purchased fuel in Colombia right now.
The discovery is important for what it signals, not just for what it contains. It confirms that Colombia's subsurface holds resources that decades of underinvestment failed to find. It confirms that the sector, properly opened to international capital and technology, can produce results. And it confirms that the upstream potential of the country is real.
What it does not confirm is that the fuel problem facing Colombian industrial operators will be resolved on a timeline that matters to their operations in 2026, 2027, or 2028. Think Energy Holdings operates at exactly the intersection that Sirius-2 illuminates. As an exploration and production group with a patented crude processing technology. It works with the crude oil that Colombian fields already produce, extracting and converting it into ultra-low-sulfur diesel on-site, in 90 to 120 days, capturing the upstream margin and the refining margin from the same barrel.
Colombia's largest gas discovery in history is a reason for optimism about the country's energy future. For operators who need fuel today, the answer is already in the ground. It just needs the right operator to convert it.
