    • Micro-Testing While Drilling for Rate of Penetration Optimization 

      Nystad, Magnus; Pavlov, Alexey (Chapter, 2020)
      The Rate of Penetration (ROP) is one of the key parameters related to the efficiency of the drilling process. Within the confines of operational limits, the drilling parameters affecting the ROP should be optimized to drill ...

    • Real-Time Data-Driven Drilling Optimization 

      Nystad, Magnus (Doctoral theses at NTNU;2021;348, Doctoral thesis, 2021)
      Drilling a well for exploration or production of petroleum resources is a costly and complicated procedure. There is a great potential for cost reduction by drilling safer, faster and with less Non-Productive Time (NPT). ...

    • Real-Time Minimization of Mechanical Specific Energy with Multivariable Extremum Seeking 

      Nystad, Magnus; Aadnøy, Bernt Sigve; Pavlov, Alexey (Peer reviewed; Journal article, 2021)
      Drilling more efficiently and with less non-productive time (NPT) is one of the key enablers to reduce field development costs. In this work, we investigate the application of a data-driven optimization method called ...
