%X we applied the nmo and crs (common reflector surface) approaches to a complex geological area in order to compare their performances for obtaining enhanced images. unlike nmo, crs does not depend on a previous time velocity model and uses a hyperbolic equation to estimate 2d travel times through three parameters (normal ray emergence angle, nip and n wavefront curvatures). to obtain the image a solution provided by coherence analysis algorithm was used. a low quality colombian seismic line acquired in middle magdalena basin was used, where a foothill geological area is characterized by a thrusting fault. the crs provided an enhanced image which allowed a new geological interpretation that is best constrained with other regional observations.
