Ecopetrol announces new hydrocarbon discovery in Gulf of Mexico (US)

BOGOTA, Colombia, July 28, 2017

Warrior-2 is located in the Green Canyon area of the Gulf of Mexico (United States), 190 kilometers from the coast, 11 kilometers from the K2 production field operated by Anadarko Production Corporation. The proximity to the production facilities of the Marco Polo platform will facilitate the production process, representing a clear competitive advantage.

The company drilled to a depth of 31,646 feet (9,646 meters), with a water layer of 4,122 feet (1,256 meters). The crude it found is light, and analyses are being performed to determine volume. Once the exploratory operations phase is complete, the development plan for this new discovery will be determined.

Ecopetrol is a participant in 67 blocks in the Gulf of Mexico (US) in association with top-tier companies.
