TGS-NOPEC Geophysical Co. has agreed with Sonangol EP to shoot a multiclient 3D seismic survey over nearly 12,500 sq km offshore Angola.
Work will start on blocks 36 and 37 in late January, then continue over Block 35 with acquisition scheduled to wrap up in the third quarter of 2012. Sonangol awarded the deepwater presalt blocks to E&P companies in late December 2011. The high-potential presalt hydrocarbon play off Angola lies between 2,000 and 5,000 m below sea level.
TGS has chartered vessel capacity for the project and will process the data in time and depth using its proven subsalt capability developed in similar basins.
