Article number 11222682296-6463https://repositorio.unab.cl/handle/ria/59780Indexación: Scopus.Lately, applications of signal processing, image processing, and pattern recognition have been widely introduced in geosciences, such as in the context of natural resources exploration, either petroleum or mineral, and engineering geology (Gaci and Hachay, 2014; Gaci and Hachay, 2017; Gaci et al., 2021). New methods and algorithms have been implemented to discover additional features in different research areas. In petroleum exploration, time-frequency decomposition techniques have been widely applied. The variational mode decomposition was used to detect gas affected by a coal layer in a tight sandstone reservoir located in the Ordos Basin, China. In addition, the multivariate variational mode decomposition was used to accurately estimate the absorption gradient coefficient from data acquired in the Puguang gas field, China.enMachine Learning (ML)Mineral ExplorationMining EngineeringPetroleum ExplorationSeismologyArtículoCC BY 4.0 Attribution 4.0 International Deedhttps://creativecommons.org/licenses/by/4.0/10.3389/feart.2022.1122268
