    • A decision support system for multi-target geosteering 

      Alyaev, Sergey; Suter, Erich; Bratvold, Reidar Brumer; Hong, Aojie; Luo, Xiaodong; Fossum, Kristian (Journal article; Peer reviewed, 2019-12)
      Geosteering is a sequential decision process under uncertainty. The goal of geosteering is to maximize the expected value of the well, which should be defined by an objective value-function for each operation. In this paper ...

    • Application of the quemada viscosity model for drilling fluids 

      Knutsen, Sandra; Cayeux, Eric; Saasen, Arild; Khalifeh, Mahmoud (Chapter, 2021)
      A number of different models are used to describe the shear rate dependent viscosity of drilling fluids. Most, such as the Herschel-Bulkley model, have a purely empirical basis. The Quemada model, while still empirical, ...

    • Cuttings Transport With Oil- and Water-Based Drilling Fluids 

      Ytrehus, Jan David; Lund, Bjørnar; Taghipour, Ali; Saasen, Arild (Peer reviewed; Journal article, 2024-01)
      Deviated well sections are common in most modern offshore well construction designs. In the North Sea region, which is a good example of mature areas, practically all producer or injector wells have highly deviated well ...
