Abstract: A method for predicting an occurrence of a geological feature in a geologic core image uses a backpropagation-enabled segmentation process trained by inputting multiple training geologic core images and a set of associated labels of geological features, iteratively computing a prediction of the probability of occurrence of the geological feature for the training images and adjusting the parameters in the backpropagation-enabled segmentation model until the model is trained. The trained backpropagation-enabled segmentation model is used to predict the occurrence of the geological features in non-training geologic core images. Geological features to be predicted with this method include structural features (such as veins, fractures, bedding contacts, etc.), and stratigraphic features (such as lithologic types, sedimentary structures, sedimentary facies, etc.).

Abstract: A method for predicting an occurrence of a structural feature in a core image using a backpropagation-enabled process trained by inputting a set of training images of a core image, iteratively computing a prediction of the probability of occurrence of the structural feature for the set of training images and adjusting the parameters in the backpropagation-enabled model until the model is trained. The trained backpropagation-enabled model is used to predict the occurrence of the structural features in non-training core images. The set of training images may include non-structural features and/or simulated data, including augmented images and synthetic images.

Abstract: A method for seismic geological lineation mapping, wherein a seismic dataset is collected, with information about minor lineations generated by Seismic dataset subtle structural geological features in an underground earth formation. Seismic attribute volumes are identified in the seismic dataset, relating to trace continuity, amplitude, frequency and phase. The attribute volumes may have an insufficient resolution to display the minor lineations. A seismic multivolume lithological lineation map is generated, in which single attribute 92d lineation maps generated for each of the identified seismic attribute volumes are combined to accurately display the minor lineations generated by the subtle geological features.
