oa 3-D Post-Stack Random Noise Reduction applied on 3-D seismic data from Tierra del Fuego, Argentina

3-D Fxdecon algorithms have become available over the past couple of years, and their use has greatly improved our ability to attenuate random noise on 3-D surveys. The Canadon Piedras 3-D survey, recorded on the island of Tierra del Fuego in 1994, provides a particularly good example of the application of 3-D Fxdecon on real seismic data. Prior to application of this process, stacked data were of very poor quality over most of the survey. Application of 3-D Fxdecon improved the data dramatically. Subtraction fFxdecon data from the input shows that only random noise was attenuated.
