Brazil pre-salt fields

Brazil’s pre-salt fields are large underwater oil reserves located beneath a layer of salt deep beneath the ocean floor off Brazil's coast. Discovered in the early 2000s, these fields contain vast quantities of untapped oil and natural gas trapped in complex geological formations. Extracting from these depths requires advanced technology due to high pressure, high temperatures, and challenging conditions. The development of pre-salt fields has significantly boosted Brazil's oil production, making the country a key player in global energy markets. They hold considerable economic importance but also pose technical and environmental challenges due to their depth and complexity.
