    • Classification of Drilled Lithology in Real-Time Using Deep Learning with Online Calibration 

      Arnø, Mikkel Leite; Godhavn, John-Morten; Aamo, Ole Morten (Peer reviewed; Journal article, 2021)
      Decision making to optimize the drilling operation is based on a variety of factors, among them real-time interpretation of drilled lithology. Because logging while drilling (LWD) tools are placed some meters above the ...

    • Significant surge and swab offshore Brazil induced by rig heave during drillpipe connections 

      Godhavn, John-Morten; Olorunju, B; Gorski, Dmitri; Kvernland, Martin Krister; Sant'Ana, Mateus; Aamo, Ole Morten; Sangesland, Sigbjørn (Peer reviewed; Journal article, 2021)
      In this paper, we describe measured and simulated downhole pressure variations (“surge and swab”) during drillpipe connections when drilling an ultradeepwater well offshore Brazil on Bacalhau (former Carcará) Field. Floating ...

    • Verification of downhole choke technology in a simulator using data from a North Sea well 

      Kvernland, Martin Krister; Gorski, Dmitri; Sant'Ana, Mateus; Godhavn, John-Morten; Aamo, Ole Morten; Sangesland, Sigbjørn (Journal article; Peer reviewed, 2019)
      The most important contributer to Improved Oil Recovery (IOR) on mature fields is drilling of infill wells. Managed Pressure Drilling (MPD) and Continuous Circulation System (CCS) techniques can be used for improved control ...
