    • Can Heating Induce Borehole Closure? 

      Xie, Xiyang; Bauer, Andreas; Stenebråten, Jørn; Bakheim, Sigurd; Lavrov, Alexandre; Fjær, Erling; Kristiansen, Tron Golder (Peer reviewed; Journal article, 2020)
      The current study shows that heating a cased borehole in low-permeability shale rock can induce plastic deformation, leading to the closure of the casing annulus and decreasing annulus connectivity. The thermally induced ...

    • Productivity Decline Mechanisms in Gravel Packed Perforations 

      Berntsen, Andreas Nicolas; Papamichos, Euripides; Xie, Xiyang; Li, Gang; Yao, Ziheng (Peer reviewed; Journal article, 2023)
      In a cased hole gravel pack completion, perforations are packed with proppant to both mechanically support the perforation cavity, and to filter any produced sand before it reaches the surface. Poor perforation packing ...

    • Time-dependent closure of a borehole in a viscoplastic rock 

      Xie, Xiyang; Fjær, Erling; Detournay, Emmanuel (Peer reviewed; Journal article, 2019)
      The paper describes a model to predict and analyze the time-dependent closure of a borehole drilled in a soft rock subjected to an initial isotropic stress, and the build-up of stress on a rigid casing after contact with ...
