???? 據(jù)油氣新聞2月22日新聞消息稱，哥倫比亞國家石油公司今天宣布了截止2020年12月31日的綜合原油、凝析油和天然氣探明儲量（根據(jù)國際標準貨幣單位為1P儲量）。儲量根據(jù)美國證券交易委員會(SEC)的標準和方法估算的。
????截至2020年底，哥倫比亞國家石油公司的凈探明儲量總計為17.7億桶油當量(MBOE)，較2019年的18.93億桶油當量減少6.5%。儲量替代率為48％，平均儲量壽命為7.5年。天然氣儲量占總量的29%，平均儲量壽命為10.1年，而液體儲量占剩下的71%，平均儲量壽命為6.8年。
????已探明儲量的減少主要是由于用于估價的碳氫化合物價格下降了32%。根據(jù)SEC的方法，2020年的儲量估值中使用的布倫特價格為43美元/桶，而2019年為63美元/桶。哥倫比亞國家石油公司估計，價格效應導致儲量減少2.15億桶油當量，部分被不同油田(如Rubiales和Ca?o Sur)新鉆井項目增加的1.14億桶油當量所抵消。
????在提高采收率方面，有1.13億桶的正變化，這主要是由于新增了與Chichimene和Castilla等油田注水相關(guān)的新項目的儲量。
????對儲量余額貢獻最大的是由哥倫比亞國家石油公司直接運營的Castilla、Chichimene和Rubiales油田。
????哥倫比亞國家石油公司擁有85%的已探明儲量，而其他集團公司擁有15%。

????Ecopetrol’s proven reserves balance reaches 1,770 million barrels of oil equivalent at the end of 2020
????Ecopetrol S.A. (BVC: ECOPETROL;NYSE: EC) announced today the Company’s consolidated crude oil, condensates and natural gas proven reserves (1P reserves, according to the standard international denomination) as of December 31, 2020. Reserves were estimated based on US Securities and Exchange Commission (SEC) standards and methods.
????By the end of 2020, the Ecopetrol Group’s net proven reserves totalled 1,770 million barrels of oil equivalent (MBOE), which represents a 6.5% decrease versus 2019 (1,893 MBOE). The reserves replacement ratio was 48%, with an average reserve life of 7.5 years. Gas reserves represented 29% of this volume, with an average reserve life of 10.1 years, while liquids reserves represented the remaining 71%, with an average reserve life of 6.8 years.
????The reduction in proven reserves was mainly due to the 32% decrease in hydrocarbon prices used for the valuation. According to the SEC methodology, the Brent price used for the 2020 valuation of reserves was US$43 per Brent barrel, versus US$63 used for 2019. Ecopetrol estimates that the price effect led to a decrease in reserves of 215 MBOE, which was partially offset by the addition of 114 MBOE attributable to new drilling projects in different fields, such as Rubiales and Ca?o Sur.
????In terms of enhanced recovery, there was a positive variation of 113 MBOE, primarily due to the incorporation of reserves from new projects mainly associated with water injection in fields such as Chichimene and Castilla.
????The largest contributions to the reserves balance came from the Castilla, Chichimene, and Rubiales fields, which are operated directly by Ecopetrol.
????Ecopetrol S.A. owns 85% of the proven reserves, while the other group companies own 15%.
