Petrobras informs a new gas discovery in the Sandia-1 exploratory well, located in Block GUA-OFF-O in deep waters offshore Colombia.

The Sandia-1 well is located approximately 42 kilometers from the coast, at a water depth of 1251 meters and 18 kilometers from the Sirius-1 (discovery) and Sirius-2 (appraisal) wells and 9 kilometers from the Copoazu-1 well (discovery), highlighting the gas potential in Colombia´s offshore, adding volumes that will contribute to the region´s energy security.

The drilling of the Sandia-1 well started on 06/12/2026 and reached its final depth on 07/29/2026 following high operational standards and respecting the environment and people. The zones where gas was detected are being carefully evaluated through well logs and will later be analyzed in the laboratory analyses.

Petrobras’ activities in Block GUA-OFF-0 are aligned with the company’s long-term strategy, aiming to replenish oil and gas reserves through exploration of new frontiers and partnerships with other companies, contributing to the supply of global energy demand during the energy transition.

Petrobras, through its subsidiary Petrobras International Braspetro B.V – Colombia Branch (PIB-COL), acts as the operator of the consortium (44.44% interest), in partnership with Ecopetrol S.A. (55.56% interest).
