    • Automated porosity estimation using CT-scans of extracted core data 

      Chawshin, Kurdistan; Berg, Carl Fredrik; Varagnolo, Damiano; Lopez, Olivier (Peer reviewed; Journal article, 2022)
      Estimation of porosity at a millimeter scale would be an order of magnitude finer resolution than traditional logging techniques. This enables proper description of reservoirs with thin layers and fine scale heterogeneities. ...

    • Classifying Lithofacies from Textural Features in Whole Core CT-Scan Images 

      Chawshin, Kurdistan; Gonzalez, Andres; Berg, Carl Fredrik; Varagnolo, Damiano; Heidari, Zoya; Lopez, Olivier (Peer reviewed; Journal article, 2021)
      X-ray computerized tomography (CT) is a nondestructive method of providing information about the internal composition and structure of whole core reservoir samples. In this study we propose a method to classify lithology. ...

    • Lithology classification of whole core CT scans using convolutional neural networks 

      Chawshin, Kurdistan; Berg, Carl Fredrik; Varagnolo, Damiano; Lopez, Olivier (Journal article; Peer reviewed, 2021)

    • Lithology classification of whole core CT scans using convolutional neural networks 

      Chawshin, Kurdistan; Berg, Carl Fredrik; Varagnolo, Damiano; Lopez, Olivier (Peer reviewed; Journal article, 2021)
      X-ray computerized tomography (CT) images as digital representations of whole cores can provide valuable information on the composition and internal structure of cores extracted from wells. Incorporation of millimeter-scale ...

    • Resistivity Estimation Using Convolutional Neural Networks 

      Bui, Richard Che (Master thesis, 2021)
      Denne oppgaven undersøker egnetheten av å anvende 2D tverrsnitt av 3D kjerneprøver i form av CT-scan data sammen med konvolusjonelle nevrale nettverk(CNN) for å bygge modeller for prediksjon av resistivitet. En av de viktige ...

    • Shuffle & untangle: novel untangle methods for solving the tanglegram layout problem 

      Nguyen, van Nghia; Chawshin, Kurdistan; Berg, Carl Fredrik; Varagnolo, Damiano (Peer reviewed; Journal article, 2022)
      Motivation A tanglegram is a plot of two-tree-like diagrams, one facing the other, and having their labels connected by inter-tree edges. These two trees, which could be both phylogenetic trees and dendrograms stemming ...
