Located 404 kilometers offshore from Rio de Janeiro, this massive hydrocarbon find sits beneath 2,372 meters of water depth, demonstrating the technological sophistication required for modern deepwater operations. The exploration well, designated 1-BP-13-SPS, penetrated to a remarkable 5,855 meters total depth, revealing what BP characterizes as its largest exploration success in 25 years.
Laboratory analysis has revealed a gross hydrocarbon column of approximately 1,000 meters, significantly exceeding initial estimates of 500 meters. This substantial column comprises distinct zones: a 100-meter gross oil layer and an extensive 900-meter liquids-rich gas-condensate section. The discovery spans an areal extent exceeding 300 square kilometers, indicating substantial lateral distribution across high-quality pre-salt carbonate formations that typically exhibit superior reservoir characteristics compared to conventional sandstone sequences.
Geographic Location and Strategic Positioning
The Santos Basin has emerged as Brazil's premier petroleum province, with the Bumerangue discovery positioned within the pre-salt play that has revolutionized South American energy production. Pre-salt formations, characterized by their position beneath thick salt layers deposited millions of years ago, contain some of the world's highest-quality reservoir rocks. These carbonate formations demonstrate exceptional porosity and permeability properties, enabling efficient hydrocarbon extraction despite extreme water depths and technical complexity.
The specific positioning 404 kilometers from Rio de Janeiro places Bumerangue within established shipping lanes and potential pipeline corridors, offering logistical advantages for future development. The 2,372-meter water depth represents the sweet spot for deepwater technology applications, deep enough to access premium pre-salt reservoirs while remaining within proven operational capabilities for floating production systems and subsea infrastructure.
Technical Specifications That Define the Discovery
The reservoir quality encountered at Bumerangue demonstrates characteristics that support BP's confidence in development feasibility. High-grade pre-salt carbonate formations typically exhibit:
• Porosity values ranging from 15-25 percent, enabling substantial hydrocarbon storage capacity
