Petrobras has confirmed a new gas discovery at the Copoazu-1 exploratory well in deepwater offshore Colombia, adding to the gas potential identified in the country’s offshore area and increasing volumes that could support regional energy security.
The company said gas-bearing intervals were identified not only in the main target but also in an additional objective. Electric logs and fluid sampling confirmed the presence of gas, giving the result added importance within the exploration campaign in Block GUA-OFF-0.
Copoazu-1 is located about 36 km off the Colombian coast in a water depth of 964 m. The well is also 8 km from the Sirius-1 discovery and Sirius-2 appraisal wells, a position Petrobras said reinforces its relevance in the block’s broader exploration context.
The well was spud on 11 November 2025. Petrobras said drilling is progressing safely, with attention to the environment and people involved in the operation.
The company added that the gas-bearing intervals will be examined further through laboratory analysis. According to Petrobras, its work in Block GUA-OFF-0 is aligned with a long-term strategy to replenish oil and gas reserves through exploration in new frontiers and through partnerships with other companies.
Petrobras said this approach is intended to support global energy demand during the energy transition. Through Petrobras International Braspetro B.V – Colombia Branch, the company operates the consortium with a 44.44% interest, while Ecopetrol holds 55.56%.
The offshore drilling campaign is being carried out with the semi-submersible rig Noble Discoverer. Petrobras first hired the unit in December 2023 for offshore drilling services in Colombia and extended the contract by 390 days in April 2025.
Built in 2009, Noble Discoverer is a sixth-generation semi-submersible drilling rig capable of operating in water depths of up to 3.1 km and drilling to a maximum depth of 12.2 km.
