Attenuation of diffracted multiples with an apex-shifted tangent-squared radon transform in image space.
Dec 01, 2006; Alvarez, Gabriel ... ABSTRACT In this paper, a method to attenuate diffracted multiples with an apex-shifted tangent-squared Radon transform in angle domain common image gathers (ADCIG) is proposed. Usually, where diffracted multiples are a problem, the wavefield propagation is complex and the ...
Stacking on common reflection surface with multiparameter traveltime.
Dec 01, 2006; Contreras, Andres Cardenas ... ABSTRACT Commonly seismic images are displayed in time domain because the model in depth can be known only in well logs. To produce seismic sections, pre and post stack processing approaches use time or depth velocity models whereas the common refection method does not, instead ...
Seismic hazard map for the Italian territory using macroseismic data.
Dec 01, 2006; Gomez C., Augusto A. ... Abstract A seismic hazard map, in terms of macroseismic intensity, is proposed for the Italian continental territory and Sicily, which has a 10% probability of exceedance in 50 years. The methodology used here was first proposed by Cornell (1968), which requires information ...
Isostatically disturbed terrain of northwestern Andes mountains from spectrally correlated free-air and gravity terrain data.
Dec 01, 2006; Hernandez, Orlando P. ... ABSTRACT Recently revised models on global tectonics describe the convergence of the North Andes, Nazca, Caribbean and South American Plates and their seismicity, volcanism, active faulting and extreme topography. The current plate boundaries of the area are mainly interpreted ...
Geology of the Florencia gold--telluride deposit (Camaguey, Cuba) and some metallurgical considerations.
Dec 01, 2006 ... ABSTRACT This paper describes the results from a study of the Florencia gold-telluride deposit in Central Cuba, including mineralogical, petrographical, microprobe and chemical analysis. Valuable information is provided for the exploration, mining and processing of gold ores ...
Dissimilarity-based classification of seismic signals at Nevado del Ruiz Volcano.
Dec 01, 2006; Orozco, Mauricio ... ABSTRACT Automatic classification of seismic signals has been typically carried out on feature-based representations. Recent research works have shown that constructing classifiers on dissimilarity representations is a more practical and, sometimes, a more accurate solution for ...
Improving vertical and lateral resolution by stretch-free, horizon-oriented imaging.
Dec 01, 2006; Perez, Gabriel ... ABSTRACT The pre-stack Kirchhoff migration is implemented for delivering wavelet stretch-free imaged data, if the migration is (ideally) limited to the wavelet corresponding to a target horizon. Avoiding wavelet stretch provides long-offset imaged data, far beyond what is ...
