bp made an oil and gas discovery at the Bumerangue prospect deepwater offshore Brazil in Santos basin.

The company drilled exploration well 1-BP-13-SPS at Bumerangue block, 404 km from Rio de Janeiro in 2,372 m of water. The well was drilled to 5,855-m TD and intersected the reservoir about 500 m below the crest of the structure. The well penetrated an estimated 500-m gross hydrocarbon column in high-quality pre-salt carbonate reservoir with an areal extent larger than 300 sq km.

Results from the rig-site analysis indicate elevated levels of carbon dioxide, and bp will analyze the reservoir fluids to characterize the reservoir and fluids discovered to determine the potential of Bumerangue block. bp expects it to be its largest discovery since discovering Shah Deniz gas field in the Caspian Sea in 1999.

Further appraisal activities are planned, subject to regulatory approval. In addition to the Bumerangue prospect drilling campaign this year, an exploration well is planned for Tupinambá block in 2026.

bp holds 100% participation in the block with Pré-Sal Petróleo SA as the production-sharing contract manager.
