Chevron launches seismic survey in Amazon Mouth Basin, Brazil's top oil frontier

Chevron, via SLB and Shearwater, will run a multiclient 3D seismic survey in ultra-deep waters off Amapá to evaluate blocks in the Amazon River Mouth Basin, following Petrobras' discovery of 'extremely high quality' oil. The move signals Chevron's confidence in the basin's potential and could accelerate exploration in a region with significant environmental sensitivity. Uncertainty remains over regulatory approvals and the commercial viability of any future discoveries.
