    • A novel model-based scheme for kick and loss mitigation during drilling 

      Hauge, Espen; Aamo, Ole Morten; Godhavn, John-Morten; Nygaard, Olav Gerhard Haukenes (Journal article; Peer reviewed, 2013)
      A model-based in-/out-flux detection scheme for managed pressure drilling is presented. We apply a globally exponentially stable adaptive observer which estimates the unknown states and parameters of the hydraulic system ...

    • Disturbance Rejection by Feedback Control in Offshore Drilling: Experimental Results 

      Albert, Anders; Aamo, Ole Morten; Godhavn, John-Morten; Pavlov, Alexey (Journal article; Peer reviewed, 2014)
      As oil exploration and development costs rise, the oil industry increases its efforts to improve oil recovery (IOR) from existing fields. IOR is achieved mainly by drilling more wells, but drilling in partially depleted ...

    • Model Based Early Kick/Loss Detection and Attenuation with Topside Sensing in MPD 

      Jinasena, Asanthi; Holta, Haavard H. F.; Jondahl, Morten Hansen; Welahettige, Prasanna Kumara Welahetti; Aamo, Ole Morten; Sharma, Roshan; Viumdal, Håkon; Lie, Bernt (Peer reviewed; Journal article, 2020)
      Early kick/loss detection is a crucial part of safe well control, and it plays a major role in the reduction of risk and non-productive time in drilling. In conventional drilling, topside sensing is used for early kick/loss ...

    • 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 ...
