Paper Summary

TGS acquired a high resolution multi-client 3D seismic survey over Blocks 35, 36 and 37 in the Kwanza Basin offshore Angola. A 3D Kirchhoff and Reverse Time Migration (RTM) Pre-Stack Depth Migration (PSDM) was undertaken to produce a more accurate velocity model, enhance event placement and improve salt boundaries and sub-salt imaging. As the first exploration period (January 2012 – December 2016) nears its end, we look at progress so far and consider a possible future exploration strategy
