Petrobras (PETR4) announced on Monday, August 3, 2026, the discovery of a new gas accumulation in the exploratory well Sandia-1, located in block GUA-OFF-0, in deep waters off Colombia. The well is approximately 42 kilometers off the Colombian coast and at a water depth of 1,251 meters.
According to the company, Sandia-1 is 18 kilometers from the discovery well Sirius-1 and the appraisal well Sirius-2, and 9 kilometers from the discovery well Copoazu-1.

The intervals with gas presence are being evaluated by well logs and will later be characterized through laboratory analyses.
