Abstract
JIMENEZ, Eduardo; VARGAS, Carlos A and MONTES, Luis A. CRS SEISMIC PROCESSING OF A GEOLOGICAL COMPLEX AREA. Earth Sci. Res. J. [online]. 2009, vol.13, n.2, pp.134-139. ISSN 1794-6190.
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.
