Petrobras confirms the discovery of natural gas accumulation in the Uchuva-1 exploratory well, drilled in deep waters of Colombia, 32 kilometers off the coast and 76 kilometers from the city of Santa Marta, in a water depth of approximately 830 meters.

The Uchuva-1 well was drilled in the Tayrona Block, with Petrobras as the operator (44.44% work interest), in partnership with Ecopetrol, with 55.56% work interest.

This discovery is the result of the consortium''s actions to enhance the use of data through the application of new geological and geophysical technological solutions, added to the expertise in deepwater operations.

The Tayrona Block is in Petrobras'' portfolio for active portfolio management and the opening of this new frontier is aligned with the company''s strategic pillar of maximizing its value with a focus on exploration of deep and ultradeep water assets. The result achieved increases the prospects for developing a new frontier of exploration and production in Colombia.

The consortium will continue its activities in the Tayrona Block, aiming to assess the dimensions of the new gas accumulation.

Petrobras has upwards of 100 production platforms, 16 refineries, 30,000 kilometers of pipelines and more than 6,000 service stations. Our proved reserves are around 14 billion barrels of oil, a figure expected to double in the next few years. With the discovery of oil and gas in the pre-salt region, Brazil may become the world's fourth biggest oil producer in 2030.

We have built a track record of overcoming challenges since 1953, when the company was created. The main one was developing technology to explore and produce oil in deep and ultra-deep waters, where upwards of 90% of our reserves are nestled. With innovation and daringness, we are now the Brazilian company that makes the applies for the most patents in Brazil and abroad.
