Colombia's Natural Gas Reserves Fall 17%, Tightening Supply Outlook

A new government report highlights a significant shift in Colombia's natural gas outlook, putting greater focus on future supply sources and upcoming energy policy decisions.

(Reuters) — Colombia's natural gas reserves fell sharply in 2025, according to a government report published on June 23, a setback for a country already under pressure to secure future domestic supply.

The report showed proven gas reserves dropped nearly 17%, while oil reserves edged down only slightly.

Authorities said Colombia still has nearly six years of gas supply at current production rates, while oil reserves cover more than seven years.

They also pointed to offshore Caribbean gas prospects and stronger reserve replacement in oil as signs the longer-term outlook could improve.

The government said discoveries and contingent gas resources in the Caribbean could help bolster supply in coming years, while proven reserves are expected to generate substantial future royalty income for the country.

Colombia has been facing declining gas output from mature legacy fields while President Gustavo Petro's energy-transition policy has included a halt to new exploration contract awards.

Petro's successor, set to take office in early August, has vowed to kickstart the industry. President-elect Abelardo de la Espriella has said he wants to resume new oil and gas exploration contracts and allow fracking.
