Reserves were estimated based on the United States and Exchange Commission (SEC) standards and methodology. 99% of the reserves were audited by three recognized independent specialized firms (Ryder Scott Company, DeGolyer and MacNaughton and Gaffney, Cline & Associates).


At year-end 2023, the net proven reserves of the Ecopetrol Group amounted to 1,883 million barrels of oil equivalent, maintaining the average levels of the last 9 years. The 2023 reserves were valued based on a Brent reference price of 82.80 USD/Bl, a 15.5% decrease in price, as compared to a Brent of 97.95 USD/Bl in 2022.

An organic incorporation of 307 MBPE was achieved in 2023, which represented a 43% increase as compared to the organic incorporation in 2022, mainly as a result of new projects, better forecasts of production fields, increased prospects for enhanced recovery, extensions and discoveries. However, the incorporation of reserves decreased by 188 MBPE, as a result of economic factors such as the fall in the Brent crude oil price and inflationary effects, as well as changes in technical conditions, mainly, water intrusion, in fields such as Ballena, Cupiagua and Recetor. The above resulted in a positive net incorporation of 119 MBPE.

Additionally, during 2023, production discounted 247 MBPE.

The Reserve Replacement Ratio (RRR) was 48%, which includes the increase in production for the period 2023. The average reserve life was equivalent to 7.6 years.

Of the 119 MBPE incorporated in 2023, 93 MBPE were the result of the better capacity for execution and implementation of improved recovery expansion projects in fields such as Chichimene, Castilla and Akacias, among others. In addition, fields such as Cano Sur and Rubiales presented positive reserve revisions due to good production performance and new drilling projects to implement in the future.

In 2023, proven developed reserves grew around 4% compared to 2022, evidencing an improvement in the Company's execution capacity.
