Common-offset CRS for advanced imaging in complex geological settings

Increasingly challenging exploration targets with respect to the geological complexity and data quality require more accurate seismic imaging. The common-offset CRS method provides an extension of the CRS technology to such targets as we demonstrate in this case study for complex 2D over thrust data. While both zero- and common-offset CRS stack provide similar noise reduction compared to the conventional PreSTM in areas with relatively simple structure and good coupling, the common-offset results are far superior on very poor data. Moreover, using the CO CRS stack in depth velocity model building can help in event picking and provides a better defined semblance.
