With exploration targets located in increasingly complex geological settings such as compressiv foothills areas, seismic imaging becomes extremely challenging. The difficulties are not only for depth imaging but also for time imaging since the conventional time processing techniques have reached their limits in such context. In this paper, we apply the Common-offset CSR technique to very poor 2D land data and demonstrate the significant imaging uplift bring by this method to such complex data. Moreover, the decrease in imaging quality due to a reasonable reduction of the field acqusition effort can also be compensated by the application of the Common-offset technique.
