Ecopetrol Group increases its hydrocarbon reserves, proven reserves mount to 1,659 million barrels-equivalent at 2017 close

February 19, 2018


BOGOTÁ, Colombia, Feb. 19, 2018 /PRNewswire/ — Ecopetrol (BVC: ECOPETROL; NYSE: EC) today announced its proven reserves of oil, condensate and natural gas (1P reserves), including its share in affiliates and subsidiaries, as of December 31, 2017.

Reserves were estimated based on US Securities and Exchange Commission (SEC) standards and methodologies. 99% of the reserves were audited by two well-known, independent, specialized firms (Ryder Scott Company and Degolyer and MacNaughton).

At the 2017 close, the Ecopetrol Group’s net proven reserves were 1,659 million barrels of oil-equivalent. The reserve replacement index was 126%, with average reserve life equivalent to 7.1 years.

95% of the proven reserves are owned by Ecopetrol S.A., while Hocol, Ecopetrol America and the Equión and Savia Perú interests contributed 5%. Ecopetrol S.A. has an average reserve life of 7.4 years.

In 2017, the Ecopetrol Group incorporated 295 million barrels of oil-equivalent of proven reserves, representing a positive change in the reserves incorporation trend in recent years. The year’s total accumulated production was 234 million barrels of oil-equivalent.

The SEC price used for valuation of the 2017 reserves was USD 54.93 per Brent barrel, versus USD 44.49 per Brent barrel in 2016. Ecopetrol estimates that 94 million barrels of oil equivalent were recovered as a result of the higher price effect due to the extension of the fields’ economic limit and the incorporation of new projects. It is further estimated that the company’s technical management and financial optimization of assets contributed 201 million barrels of oil equivalent.

We note that much of the increase in proven reserves (73 MBOE) is due to the results of the Recovery Factor Increase program, the principal gains of which occurred in fields such as Chichimene, Castilla, Casabe and Tibú. This result is very satisfactory, as it is one of the pillars of the company’s growth in reserves and production.
