Mutual thin-bed interference modeling suited for the case study area was performed using a well-tying well-based extracted wavelet assumed to be representative of the wavelet embedded on the input seismic data. The long coda of this wavelet is also present on the corresponding thin-bed waveform, indicating the possibility of more complex mutual interference patterns between thin beds and mutual interference at farther vertical separations between thin beds compared with what would occur for an embedded wavelet with a shorter coda. The observed lateral changes on preferential frequency and phase illumination on the seismic data are attributable to collocated lateral changes in the stacking patterns and variable occurrence of vertically adjacent thin beds, which are interpreted as lateral sediment deposition changes induced by the syndepositional activity of the secondary faults. This is a geologic scenario that had not been previously considered on the area until the evidence of this case study provide indirect support for it.\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-14a3d90 elementor-widget elementor-widget-button\" data-id=\"14a3d90\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/luminageo.com\/wp-content\/uploads\/2025\/01\/Joint-time-variant-spectral-analysis_Part-2.pdf\" target=\"_blank\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon\">\n\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" viewBox=\"0 0 12 12\" fill=\"none\"><path d=\"M5 3V4H2.5V9.5H8V7H9V10C9 10.2761 8.77615 10.5 8.5 10.5H2C1.72386 10.5 1.5 10.2761 1.5 10V3.5C1.5 3.22386 1.72386 3 2 3H5ZM10.5 1.5V5.5H9.5L9.49995 3.2065L5.60355 7.10355L4.89644 6.39645L8.79245 2.5H6.5V1.5H10.5Z\" fill=\"#4D4D4D\"><\/path><\/svg>\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Atached file<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div data-elementor-type=\"loop-item\" data-elementor-id=\"1823\" class=\"elementor elementor-1823 e-loop-item e-loop-item-2393 post-2393 publication type-publication status-publish hentry tag-phase-decomposition\" data-elementor-post-type=\"elementor_library\" data-custom-edit-handle=\"1\">\n\t\t\t<div class=\"elementor-element elementor-element-bc7d0b8 e-flex e-con-boxed e-con e-parent\" data-id=\"bc7d0b8\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-f9eab5a e-con-full e-flex e-con e-child\" data-id=\"f9eab5a\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3fa9c01 elementor-widget elementor-widget-theme-post-title elementor-page-title elementor-widget-heading\" data-id=\"3fa9c01\" data-element_type=\"widget\" data-widget_type=\"theme-post-title.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h1 class=\"elementor-heading-title elementor-size-default\">Joint time-variant spectral analysis \u2014 Part 1: Forward modeling the effects of thin-bed layering<\/h1>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7f4347b elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"7f4347b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tRamses G.

The NTG signature is observed on the amplitude (magnitude) responses, rather than any specific frequency or phase component. On the other hand, external mutual thin-bed interference can significantly change the preferred phase component for each participating target. This phenomenon is largely driven by the embedded seismic wavelet that determines the nominal seismic response of an isolated thin layer and what phase component would preferentially illuminate it. For vertical separations between mutually interfering and elastically comparable thin beds in which mutual constructive interference is achieved, the target bed will be preferentially illuminated at a phase component that is very close to that of a total seismic isolation, whereas the occurrence of mutual destructive interference will cause a significant departure on the phase preferential illumination from that of an isolated seismic thin bed. All these observations can provide an avenue to yield more robust stratigraphic interpretations of seismic data and enhance the confidence on subsurface description.\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-14a3d90 elementor-widget elementor-widget-button\" data-id=\"14a3d90\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/luminageo.com\/wp-content\/uploads\/2025\/01\/Joint-time-variant-spectral-analysis_Part-1.pdf\" target=\"_blank\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon\">\n\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" viewBox=\"0 0 12 12\" fill=\"none\"><path d=\"M5 3V4H2.5V9.5H8V7H9V10C9 10.2761 8.77615 10.5 8.5 10.5H2C1.72386 10.5 1.5 10.2761 1.5 10V3.5C1.5 3.22386 1.72386 3 2 3H5ZM10.5 1.5V5.5H9.5L9.49995 3.2065L5.60355 7.10355L4.89644 6.39645L8.79245 2.5H6.5V1.5H10.5Z\" fill=\"#4D4D4D\"><\/path><\/svg>\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Atached file<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div data-elementor-type=\"loop-item\" data-elementor-id=\"1823\" class=\"elementor elementor-1823 e-loop-item e-loop-item-2392 post-2392 publication type-publication status-publish hentry tag-phase-decomposition\" data-elementor-post-type=\"elementor_library\" data-custom-edit-handle=\"1\">\n\t\t\t<div class=\"elementor-element elementor-element-bc7d0b8 e-flex e-con-boxed e-con e-parent\" data-id=\"bc7d0b8\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-f9eab5a e-con-full e-flex e-con e-child\" data-id=\"f9eab5a\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3fa9c01 elementor-widget elementor-widget-theme-post-title elementor-page-title elementor-widget-heading\" data-id=\"3fa9c01\" data-element_type=\"widget\" data-widget_type=\"theme-post-title.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h1 class=\"elementor-heading-title elementor-size-default\">Phase Decomposition as a Hydrocarbon Indicator: A Case Study<\/h1>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7f4347b elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"7f4347b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tMeza, Haughey, Castagna, Barbato, Portniaguine \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f880b63 elementor-widget elementor-widget-theme-post-excerpt\" data-id=\"f880b63\" data-element_type=\"widget\" data-widget_type=\"theme-post-excerpt.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\tPhase decomposition is applied to low-impedance hydrocarbon-bearing sands in a clastic section where sand thicknesses vary from the vicinity of tuning to well below tuning.

For seismically thin layers, phase components are particularly useful in simplifying seismic interpretation.\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-14a3d90 elementor-widget elementor-widget-button\" data-id=\"14a3d90\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/luminageo.com\/wp-content\/uploads\/2025\/01\/int-2015-01502E1.pdf\" target=\"_blank\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon\">\n\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" viewBox=\"0 0 12 12\" fill=\"none\"><path d=\"M5 3V4H2.5V9.5H8V7H9V10C9 10.2761 8.77615 10.5 8.5 10.5H2C1.72386 10.5 1.5 10.2761 1.5 10V3.5C1.5 3.22386 1.72386 3 2 3H5ZM10.5 1.5V5.5H9.5L9.49995 3.2065L5.60355 7.10355L4.89644 6.39645L8.79245 2.5H6.5V1.5H10.5Z\" fill=\"#4D4D4D\"><\/path><\/svg>\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Atached file<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div data-elementor-type=\"loop-item\" data-elementor-id=\"1823\" class=\"elementor elementor-1823 e-loop-item e-loop-item-2386 post-2386 publication type-publication status-publish hentry tag-phase-decomposition\" data-elementor-post-type=\"elementor_library\" data-custom-edit-handle=\"1\">\n\t\t\t<div class=\"elementor-element elementor-element-bc7d0b8 e-flex e-con-boxed e-con e-parent\" data-id=\"bc7d0b8\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-f9eab5a e-con-full e-flex e-con e-child\" data-id=\"f9eab5a\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3fa9c01 elementor-widget elementor-widget-theme-post-title elementor-page-title elementor-widget-heading\" data-id=\"3fa9c01\" data-element_type=\"widget\" data-widget_type=\"theme-post-title.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h1 class=\"elementor-heading-title elementor-size-default\">Phase Decomposition as a DHI in Bright Spot Regimes: A Gulf of Mexico Case Study<\/h1>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7f4347b elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"7f4347b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tUmberto Barbato*, Lumina Geophysical , Oleg Portniaguine, Lumina Technologies, Ben Winkelman, Talos Energy, John Castagna, University of Houston \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f880b63 elementor-widget elementor-widget-theme-post-excerpt\" data-id=\"f880b63\" data-element_type=\"widget\" data-widget_type=\"theme-post-excerpt.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\tPhase decomposition is used as a Direct Hydrocarbon Indicator in low impedance light oil bearing sands in a deepwater Gulf of Mexico seismic dataset.
