Fortunately some clients saw the opportunity for some great deals.

Schlumberger and TGS-NOPEC also operating in Brazil established their record with the Geco Marlin while shooting the Brazil'99 85,000 km. Spec survey. Claimed as the "largest contiguous 2D survey in history", Brazil'99 covers the Santos, Campos and Espirito Santo Basins. Follow the survey's progress on
