BOGOTA, Colombia, Feb. 20, 2025 /PRNewswire/ -- Ecopetrol S.A. (BVC: ECOPETROL, NYSE: EC) announced today its proven reserves of oil, condensates, and natural gas (1P reserves), which includes the results of Ecopetrol S.A., its subsidiaries and affiliates, as of December 31, 2024.

99.2% of the reserves were estimated and certified based on the standards and methodology of the US Securities and Exchange Commission (SEC) by three recognized, specialized, and independent firms (Ryder Scott Company, DeGolyer and MacNaughton, and Gaffney, Cline & Associates), and the remaining 0.8%, were certified by Ecopetrol's Resources and Reserves Management. The 2024 reserves were valued based on the Brent reference price of USD 79.7/bbl compared to USD 82.8/bbl used in 2023.

By the end of 2024, the Ecopetrol Group's net proven reserves amounted 1,893 MBOE (+10 MBOE versus 2023). The reserve replacement ratio was 104%², and the average reserve life was 7.6 years (7.8 years for liquids and 6.7 years for gas).

In 2024, the Ecopetrol Group incorporated 260 MBOE of proven reserves, the highest in the last three years, of which 244.3 MBOE were crude oil and 15.3 MBOE gas, for a total accumulated production for the year of 250 MBOE³, the highest in the last nine years. Of the total balance of proven reserves, 80% are liquids reserves and 20% are gas reserves.

Organically, 231 MBOE⁴ were incorporated through the timely maturation of new projects and the execution and implementation of primary development and enhanced recovery expansion projects in fields like Caño Sur, Rubiales, Castilla, Chichimene, Akacias, Pauto-Floreña, La Cira-Infantas, Apiay-Suria, Palogrande, among others.

Inorganically, net of acquisitions and divestments, 29 MBOE were incorporated by the Ecopetrol Group in 2024, including the successful acquisition of the 45% stake from Repsol Colombia Oil & Gas in the CPO-09 block, located in the Meta department, consolidating 100% ownership of this strategic asset in the Piedemonte Llanero, by adding 32 MBOE.

The increase in reserves achieved in 2024 is one of the pillars of the Ecopetrol Group's strategy to ensure its long-term sustainability.

On the gas front, the net incorporation of 15 MBOE stands out, due to: i) projects related with new development wells and infrastructure optimization with pressure reduction in the Piedemonte Llanero in the Pauto and Floreña fields, ii) execution plan of activities in Permian, and iii) commerciality of Arrecife, which partially offset the impacts of water intrusion in the Cupiagua, Cusiana, Guajira, and Gibraltar fields.

Ecopetrol Permian LLC incorporated 22 MBOE⁵ mainly as a result of optimizations made in drilling campaigns in the Midland and Delaware sub-basins in Texas, United States.
