bp Starts Drilling New Well in Bumerangue Block, Where It Holds 100% Stake, Expanding Its Presence in the Pre-Salt of the Santos Basin.
The British giant bp has begun drilling the pioneering well 1-BP-13-SPS in the Bumerangue block, located in the promising pre-salt region of the Santos Basin. The operation, conducted in ultra-deep waters of 2,372 meters, is carried out with the drillship Valaris Renaissance and marks another significant advancement for the company in the Brazilian oil market.
The Bumerangue block is 100% operated by bp, which acquired it during the first auction of the Permanent Sharing Offer, held in December 2022.
This move reinforces the strategic presence of the oil company in the deep-water exploration sector, consolidating its position in one of the most important regions for the global energy industry.

Pre-Salt Remains at the Center of bp’s Strategy
The pre-salt of the Santos Basin has proven to be a central pillar in bp’s operations in the country.
The start of new drilling in the Bumerangue block expands the company’s efforts in exploring oil in high-productivity areas, focusing on discovering significant reserves and increasing future production.
In addition to Bumerangue, bp had already drilled the pioneering well 1-BP-12D-RJS in the Pau Brasil block in July 2023.
One month later, in August, the company announced the identification of oil indications at the site, located at a depth of 2,283 meters, also in the Santos Basin.
bp currently leads four exploratory blocks in Brazil. In the Santos Basin, it operates the Bumerangue and Tupinambá blocks with a 100% stake.
In Pau Brasil, the company shares operations with CNOOC (30%) and Ecopetrol (20%), maintaining a 50% stake.
In the North region, specifically in the Barreirinhas Basin, bp is also the operator of the BM-BAR-346 block in partnership with Total, with an equal 50% stake.
Still in this basin, it participates in the BM-BAR-3 and BAR-M-175 (BM-BAR-5) blocks, with a 40% stake each, operated by Petrobras.
Operations in the Campos Basin Reinforce Integration with Petrobras
bp’s presence in the Campos Basin is also strategic.
The company holds a 30% stake in the C-M-477 block and 50% in the Alto de Cabo Frio Central block, both operated by Petrobras.
This integration with the Brazilian state company strengthens bp’s position in areas already recognized for their high productive potential.
