The new discovery of gas accumulation in the Copoazu-1 exploratory well, in the GUA-OFF-0 Block, is located in deep waters offshore Colombia. The drilling of the Copoazu-1 well started on Nov. 11, 2025, and is ongoing.
The Copoazu-1 well, in a water depth of 964 m, is 8 km from the partnership’s Sirius-1 gas discovery well and the Sirius-2 appraisal wells on the same block.
Drilling of Copoazu‑1 started last November, with operations still in progress. Electric logs and fluid samples led to the identification of gas-bearing intervals as well as the presence of gas in an additional objective beyond the main target area.
Laboratory analysis will follow to better define the gas-bearing region.
Petrobras International Braspetro B.V – Colombia Branch (PIB-COL) operated the GUA-OFF-) block with a 44.44% interest, with the remaining 55.56% held by Ecopetrol.
