Ecopetrol posts 1.94 Bboe in proved reserves, replaces 121% of production in 2025

(WO) — Ecopetrol reported proved reserves of 1.94 Bboe at year-end 2025, representing a 2.7% increase from 2024 and marking the company’s highest annual reserve additions in four years.

The Colombian national oil company added 300 MMboe of proved reserves during 2025 and achieved a reserves replacement ratio of 121%, driven primarily by enhanced recovery projects and improved operational performance across key producing assets. The group’s average reserve life now stands at 7.8 years.

According to Ecopetrol, the majority of reserve additions were tied to enhanced recovery and optimization programs in the Castilla, Chichimene and Akacías fields, along with improved operational management in the Rubiales and La Cira–Infantas assets. Additional contributions came from contract-related reserves recognized under agreements with Colombia’s National Hydrocarbons Agency.

The company noted that reserve growth was achieved despite a 13.9% decline in the average Brent reference price in 2025 compared with 2024. Nearly all proved reserves were independently certified by Ryder Scott, DeGolyer & MacNaughton and GaffneyCline in accordance with U.S. SEC standards.

Ecopetrol said the results reflect continued focus on recovery optimization, asset efficiency and long-term reserve sustainability across its upstream portfolio.
