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 system for providing information through a metal wall employs a device adapted to be arranged on one side of the metal wall and a magnetic-permeability element, provided at, near or connected to the device. The magnetic-permeability element is based on a material having a relative magnetic permeability of at least 2000. The disclosure also provides use of said system. The use may involve the step of optimizing the magnetic-permeability element using equivalent inductive mass (EIm). The system can for example be used to magnetically sense the location of a cable present on the outside of a wellbore tubular using a magnetic orienting tool that is located within the wellbore tubular.

Abstract: A highly active hydroprocessing catalyst that comprises a doped support impregnated with at lease one hydrogenation metal component and filled with an organic additive blend. The catalyst is made by providing a doped support particle followed by impregnating the doped support particle with a metal impregnation solution to provide a metal-impregnated doped support particle. The metal-impregnated doped support particle is dried but not calcined and impregnated with an organic additive blend component.

Abstract: The present application relates to a method and system for determining parameters of battery pulsed heating. The reference potential of the anode of the lithium-ion battery is obtained in real time in the positive and negative pulsed heating process under various heating parameters. The relationship between reference potential and threshold potential indicates whether Li plating has occurred to the lithium-ion battery. When the reference potential is smaller than the threshold potential, the first heating parameters are adjusted to avoid Li plating and improve battery life. By recording the heating parameters when the reference potential is greater than the threshold potential, it can be ensured that the pulsed heating parameters have no significant impact on the life of the battery.
