Abstract: A method for analyzing rock cores of a subterranean formation is disclosed. The method includes capturing core images of the rock cores that are collected from geographical locations in the subterranean formation, generating, by a computer processor and from the core images, sub-images by sub-dividing each of the core images, classifying, using a secondary machine learning model that automatically identifies artifacts induced from preparation of the rock cores, the sub-images into artifact-free sub-images and artifact-containing sub-images, and analyzing, using a primary machine learning model, the artifact-free sub-images to generate a core analysis result.

Abstract: Example computer-implemented methods, media, and systems for identification and characterization of geologic features in carbonate reservoir are disclosed. One example computer-implemented method includes obtaining multiple core sample images of a carbonate reservoir. The multiple core sample images are labeled using multiple feature classes, where the multiple feature classes include at least one of a vug or fracture. Multiple image patches are generated using the labeled plurality of core sample images. A machine learning model is applied to the multiple image patches to identify one or more vugs or fractures in the multiple core sample images. At least one of porosity or permeability of the carbonate reservoir is predicted using the identified one or more vugs or fractures in the multiple core sample images.

Abstract: A computer-implemented method, medium, and system for geological core property prediction using machine learning modeling are disclosed. In one computer-implemented method, multiple imagery data of a core sample of a wellbore are received. The multiple imagery data are partitioned into multiple image patches. Multiple first vectors of encoded features in a latent space are generated based on the multiple image patches. Multiple image features of the core sample of the wellbore are generated based on the multiple imagery data. Multiple second vectors of encoded features in the latent space are generated based on the multiple image features. Multiple rock properties associated with the core sample of the wellbore are predicted by running a regressor in the DFCN based on the multiple first vectors and the multiple second vectors. The multiple rock properties are provided for determining multiple properties of a subsurface reservoir that includes the wellbore.

Abstract: Techniques include flowing a multiphase fluid from a hydrocarbon production well through a conduit; measuring, with an ultrasonic tomographic multiphase flow meter (UMM), ultrasonic waveforms generated by the UMM from the multiphase fluid; measuring properties of the multiphase fluid with fluid measurement sensors coupled to the conduit; identifying the ultrasonic waveforms and the properties with a machine-learning control system; determining multiphase fractions of the multiphase fluid from the one or more ultrasonic waveforms with a first ML model; determining a total flow rate of the multiphase fluid from the measured properties of the multiphase fluid with a second ML model; and determining a volumetric flow rate of a liquid phase or a gas phase based on the determined multiphase fraction and the determined total flow rate.
