• Influence of Weight-on-Bit on Percussive Drilling Performance 

      Song, Xianfeng; Aamo, Ole Morten; Kane, Pascal-Alexandre; Detournay, Emmanuel (Peer reviewed; Journal article, 2020)
      A phenomenological model for percussive drilling systems is proposed in this paper to explain the experimentally demonstrated existence of an optimal weight-on-bit (WOB), for which the rate of penetration (ROP) is maximized. ...
    • Review of two-phase flow models for control and estimation 

      Aarsnes, Ulf Jakob Flø; Flåtten, Tore; Aamo, Ole Morten (Peer reviewed; Journal article, 2016)
      Most model-based control and estimation techniques put limitations on the structure and complexity of the models to which they are applied. This has motivated the development of simplified models of gas-liquid two-phase ...
