Of the total balance of reserves, 75% are liquid reserves and 25% are gas reserves.

The management of the development fields, reflected in an optimized and timely maturation of new projects, better execution capacity, and implementation of improved recovery enhancement projects in fields such as Chichimene, Castilla, and Akacias, among others, provided 215 MBOE of the reserves.

Additional reserves were incorporated through the acquisition and qualitative selection in areas of the Permian basin in the United States (48 MBOE).
